I just found anbother small box of hardware, mostly clamp holders, aka bossheads, and related items.
There are a few lots of items that I would be happy to sell as a group, or a few at a time, if no one buys them all.
 
First is 12 working and 2 stuck (free bonus in case you can fix them) anglular Castaloy clamp holders, these run about $200 in Ebay new, I would sell
the lot of 12 for $60, they run from like new to well used or corroded, but all working, except for the extra 2 stuck ones. https://www.ebay.com/itm/364592963348
Next I have a set of the simpler Fisher Cataloy Flexframe Hook connectors, which are designed to simply hold 2 1/2" rods tight, can be used for
lattice frames or holding clamps, but not as nice as the above ones. There are 17 of these, they run about $5 each on Ebay, I will do all 17 for $50,
under $4 each, for the entire set. (I likely have more of these mixed in other lots of hardware if you want more.) https://www.ebay.com/itm/353813567122
 
Then I have the round Kimble type 1/2 inch lattice connectors, which are little aluminum balls with allen keys to tightten them, can be installed or
taken off while lattice is intact, so very handy, but not really useful for clamps. I have 20 of these for $100, they sell for $20 new, and about
$5-8 ea used on Ebay.
https://www.dwk.com/na/kimble-12-lattice-connector
Next are 8 working and 5 non-working Ohaus round lattice connectors. They are very sturdy, but harder to assemble and take off. I would ask $50
for the entire lot. https://www.grainger.com/product/404R21
And lastly I have some mixed, but similar clamp holders, unbranded, that look like the link below, and are very sturdy clamp holders. I have 12
working ones. They sell new for a lot, about $25, but I want to go with $5 each, so $60 for the lot of 12.
https://www.arborsci.com/products/90-degree-clamp
Lastly, I just found about 6 more large Fisher 3 prong Cataloy clamps, which sell new for almost $100, I will sell them for $15, as they are are all
in almost new condition. There are a few VWR ones that are of similar quality as well.
I have many other clamps, rings, and clamp holders also, but these I have a bunch of similar items for people that want a set of matching ones. I
also have more broken ones, if anyone wants to try to fix some for cheap.

A long time ago I spoke to someone who had a microscale setup with mostly 10/18 and 14/10 joints. I found a few pieces of this that I knew I had,
but could not find for a while. Mostly a couple of 10/18 condensers and some other odd bits. If you are them or anyone who can really use some
10/18 condensers, please let me know so I can give them to you. I likely have more scattered around of small stuff, so please let me know. I also
have a number of Weaton V-bottom vials in a few sizes and styles, plus stir bars and other bits for them, if anyone is interested in them. I would
have to sell them for a little bit, but not much.

I have been asked for an updated list of available glassware, so I just finished editing the list to be as close as possible, given the flux of stuff
in and out. I have hidden most of the items with 0 inventory, but sometimes I can find those items or have one that is dirty, damaged, or recently
found. But the items shown as in stock I should have available.

Some non-equilibrated addition funnels below. I have 2 x 125 ml ones that are PTFE stopcock. The top is a TS 222 stopper, I can provide one, this
is not 24/40 compatible. There is also a graduated 125 ml one, with a 24/40 compatible top. I would ask $30 for any of them.
Also some 24/40 to 14/20 bump bulbs that I photographed for someone else, but figured I would post here before they go to Ebay. $20-25 each.
Also some Kugelrohr bulbs in many sizes and styles, all 14/20, from 5 or 10 ml up to 250, even some long ones for large amounts. They can also be
used as Rotovap bump traps, or distillation bump bulbs or small solvent resevoirs for little columns, if you really reach for uses.

Addition funnel bought from Dr.Bob was cheap, shipped fast, and arrived in great condition. Columns bought in the past from him were just the same;
fantastic. Thanks

Just want to make a note that I will be away for a few days, but will answer all messages once I get back. Thanks for all of the help cleaning out

I am back from my trip, and was asked for my email by someone, it is craigslistinnc @ gmail.com, if you email me there, I will email you back from
there and give you my real email. I get spammed on any account I post, so I have to go through a lot of mess. Sorry for the trouble.

I have some old Fisher drawer organizers left that I would like to sell, or take some offers on. Most are 18 x 19 " in size, and I have about 4 or
more types. I attached some photos of similar items. These are an older model, made of polystyrene or such, and are a little brittle from age. But
they sell new for $50-60 each, and I want to sell them for $10-20 each plus postage, or less if you buy a few. I just found a box that would hold up
to about 6 or so of them, so if anyone is willing to buy a bunch, I can make a deal, and ship them easily. They are ideal for pipettes, small parts,
small flasks, beakers, vials, and much more. I have a pile of them and will never use them all, so better to sell a few and have more space to sort
other glassware. I am having issues getting the photos to display, see the link below for the Fisher site showing most of these organizers.

Updated the spreadsheet again. It is listed below for uploading.
I keep finding graduated cylinders in smaller sizes, (10 to 100 ml), have a few sets made up of 10, 25, 50, and 100 ml sizes, including new ones for
most sizes but 25 ml. I will sell the set of 4 of them for $16 each, or $20 if you want 5, and I can fill in an extra one of whatever extra size I
can find. Still have lots of smaller erlenmeyers, volumetrics, filter flasks, and smaller multineck RBFs. Running out of small one necks in 14/20,
mostly out of 24/40 rbfs, and still have a few 29/42 ones.

Here are some photos of a bunch of 29/42 pieces that I have left and was photographing for someone, so I will post them for anyone what is interested
in 29/42 glassware. There are many adapters, short paths (with 10/30 therm joints), vacuum adapters, gas inlets, Dean starks, addition funnels, and
much more. I have more addition funnels somewhere, up to 2L size. If you should be interested in any of it, please let me know which items and
either an offer or I can give you a price. Most things would be the same price as the 24/40 equivalent item.
I also have a number of 3 and 4 necked rbfs in 29/42 with straight and vertical necks of 250 and 500 ml size. i'd ask the same price as the
equivalent 24/40 3 neck flaskand . I also have enough stuff to make one more "kit" with a claisen, dist head, condenser, gas inlets, and more.

Here are a couple of condensers I have, might sell one shortly, but I have several of the lower ones, which is a West condenser combined with a curved
vacuum adapter, all 24/40 joints, asking $25 for it. The top one is a simple West with a 24/40 bottom joint but a simple joint at the top, like for
a rubber stopper, I would only ask $10 for it.

Someone asked me about HPLC columns. I have a bunch, mostly very old, a few might be new, but most were used and then sealed and stored for years.
I am willing to sell them for very little as they are, given that I don't know if they work or not. If anyone is at an acedemic location, I will give
most away for the shipping costs. Some are likely quite expensive when new, and I suspect that many of these are usable or fixable with some
reconditioning (run water to acetonitrile and back a few times or such).
So I will be posting the columns as I dig them out.
Rainin Microsorb CN 80-820-C5 - new in sealed box, heavy sucker - make an offer

A few more things to post I just found. Not sure what some are, but I will describe. make me an offer if you want to make one.
From the right side: 2 long fritted gas inlets - 24/40 joint on top - 2 gas barbs, tube is about 12" long. - Asking $15
Next two (and the 2 pieces on the far left are what's left of another) are 24/40 joint with upper inlet and top open tube, and a very long (~15") open
ended tube going into the flask. No idea what this is for. Asking $15 each plus a free broken one to the first buyer.
Next a Snyder column with the middle floating ball broken. no idea if it will work, nexrly impossible to repair, happy to give to someone who buys
anything else and pay shipping.
Lastly, some sort of bubbler thing with 2 24/40 joints anda fritted tube inside. $10 or make me an offer.

Here is another set of photos of the 19-22 kit I have slowly assembled from bits and pieces. It is nearly a full setup, with a variety of flasks
(some all 19/22, some mixed with 14/20 or 24/40 joints), a few distilation heads, a claisen, 4 various condensers (one is a coil and outer jacket
combo), a few odd Soxlets that may work with some of the condensers, gas inlets, and many other pieces and various adapters. Plus some adapters to
other sizes, septa keck clips, and some stoppers. The one complex distillation head alone would sell for $400 new, but I am asking $150 for the
entire collection. Or make me an offer. This is basically every 19/22 item I have found in the last few years all combined into one lot.

I have been told the the long glass items 2 posts back might be from some "cyanide distillation apparatus", used for certain analytical digestions,
not quite sure what they are used for exactly. But I found more of them, and will likely post them on Ebay, but I have lots, so if you want to play
with one, I will sell cheap. Please don't distill cyanides with them.

I just found a few boxes of bottles, some narrow mouth 1L amber ones, some wide mouth clear bottles, and some medium mouth amber bottles. I'm happy
to sell them for $2 each, less in bulk, and would be happy to sell a box full for a good price. I also still have 100 ml clear, amber and plastic
coated narrow mouth bottles, and many others. Please let me sell you a bunch and find them a nice home.

I have another sad piece of news. Another long time collegue of mine has passed away, of an agressive cancer that spread quickly and left him little
time to prepare. He had worked with me for a while, then started his own business and ran another small chemical company for almost 30 years.
Given the speed of the cancer, he had little time to clean up and close his business, so his wife has now inherited a small lab full of glassware,
chemicals, equipment, and who knows what more. I am hoping I can help her to deal with some of it, but not quite sure of the details yet. But there
are rotovaps, hotplate/stirplates, much glassware and so much more. So if you might be interested, please let me know, but I won't have a real
inventory of what is there for a month or so.
I hope to help his wife get enough in sales to pay for the disposal of some of the waste and old chemicals he had there, which may be harder without
knowing what is in each thing. There are also larger things, overs, balances, ventalated weighing boxes, 4 fume hoods, solvent cabinets, shelves,
and much, much, more. If anyone in the NC area wants to come haul away some larger things, please let me know. I hope to sort out the glassware
within a month or so, then start selling it, there is quite a bit, from small flasks, going up to fairly large rbfs, like 5 and 12L or so. I just
want to help his wife clean out the space so she can end the lease within a few months if possible. Not quite sure how that will happen yet.

I spent a few hours in the lab today, and already have found and packed up a lot. I have several boxes of 24/40 rbfs already, 1, 2, and 3 necks, and
will find more, from 100 ml to 5L already, and there are some larger ones in the storage space, going up to 22L I think. Those will take a little
while to sort out. Lots of larger neck flasks,
There is also a wealth of other random stuff everywhere, most of which needs cleaning or sorting. Just let me know if you are looking for anything
and I will look for you, I am trying to take photos of things to post. I also packed a large box each of rbfs (3), erlenmeyers, media bottles, glass
frit funnels, and filter flasks, all from small to large.
If you want a rotovap, balance, hood, etc, feel free to come make an offer on them and haul them away. I will eventually pack up the rotovaps and
clean, test and assemble them. There are also lab benches, cabinets, drawer units, and so much more. If anyone knows someone setting up a lab,
running a small business, or such, please send them to me, here or via craiglistinnc (a) gmail.com. I have a better email, but don't post it here due
to spam issues.
Again, if you are in the market for larger rbfs, please let me know.

I have more things to prelist, working on updating the spreadsheet.
I have many media bottles, including 100, 250, 500, a few 1000 ml, 2000 ml, and even a couple 5000 ml media bottles.
i am finding lots of 24/40 rbfs, so I will be able to make a few 24/40 kits soon, they would have a 50, 100, 250, 500, and 1000 ml rbf, a condenser,
dist head, currved vacuum adapter, claisen adapter, and much more. I also have some 19/22 pear flacks (50 and 100 ml), and lots of 100 and 250 ml
14/20 pears and several 500 ml 14/20 rbfs. I also have found some 2 and 5L 24/40 single necks, with many more various large flasks that I am still
sorting through. I also have found a large amount of bulk silica gel, happy to package it up in 1 lb or 1 kg. containers, would only ask a few $
per lb, which is a bargain.
I have already had a couple local scimad people come by and get some things, there were 2 complete working rotovaps, one is already claimed, the other
may be soon, but there are several more that I have not yet checked. There are also many precious metal compounds, salts, and catalysts, if you are
looking for any, please let me know. Lots of Pd/C, PtO and PtOH, Pt ands Pd black, and some rhodium compounds. I would be happy to sell them for
their metal value alone. Even PPh3PdCl2DCM, Pdferrocenebisphosphine, and more. I am happy to make great deals for any graduate students or
professors as well.
Lots more to come, if you are looking for any specific chemicals (that are shippable) let me know, I have lots of amino acids and derivitives, amines,
acids, and more.

Found a very good 2L sep funnel, with PTFE stopcock and stopper, might have a minor chip on the drip tube, but otherwise very good to nearly new, plus
another 2 and 4L sep funnel that I am trying to clean now, not sure of the exact condition until I can clean them.
Keep finding more media bottles, have scads, please buy some. :-)
Have found more 24/40 rbfs, trying to put together some kits now.
More 29/42 rbfs, a few 1 and 2L ones, plus others.
I have several nice 14/20 dewar condensers, I'll try to get some photos once I get caught up some.
I'll try to get more photos soon, but just need to clean up everything before trying to get a photo, and that is taking a while. But making
progress on it.
A few local Sci Mad people have stopped by to help clean up and buy stuff, that has been a big help, they have bought some solvents and chemicals that
I can't easily ship, plus bigger items and more. They have helped me sort through much stuff, and I can not thank them enough. Might have a few
more come by over the next month. Have cleaned out (and sold) some flammable cabinets, have lots of wall cabinets, drawers, bench tops, hoods,
ovens, pumps, and more.

I am making great progress on the lab cleanup, thankfully. Most of the bad chemicals are now dealt with, but I have the more stable ones stored
safely, and will try to sell the ones that are safe to ship. But I am cleaning the glassware as fast as I can, but it may take weeks to get it all
done. I have several boxes of media bottles now ready to sell, I have dozens of new 100 ml amber Quorpak bottles, and many other containers. If
people want an assortment of bottles, I can do deals for med or large flat rate boxes of any mix of bottles.
I have also found lots of Ace pressure tubes of all sizes and shapes; glass stir shafts, bearings and paddles; 14/20 short path heads; bubblers, and
so much more. I will be slow to have things ready to ship, as much needs washing, but if you are interested in certain items, glassware, equipment,
or chemicals, let me know as soon as you can, and I can try to save things for you. The first people to order things will get the first choice of
thengs and the best glassware.
And thanks again to the people who have helped me cleaning the lab, as well as few others who have helped me.

Found some cases of brand new chemicals, here are a few. The celite is a huge bottle, 1 Kg, the sodium carbonate and sodium potassium tartrate
(Rochelle's Salt) are each 500 g. I would ask $20 each plus the shipping, easiest to combine a few things glass and chemicals into one package if
possible.
Also, here are some of the Parr bottles, 500 ml, for hydrogenation apparatus, which was asked about recently.

So far I have one 5L media bottle left, a few 2L media bottles left, about 10 1L ones left, a dozen or so 500 ml ones, 25 or more 250 ml ones, and
about a dozen 100 ml ones. Also have lots of amber and clear 100 ml narrow mouth qorpak bottles, some medium width 250 ml amber qorpak bottles, and
so much more.
Putting together some 24/40 kits, it may take a while to get them all complete, but trying. Grad cylinders up to 1000 ml, volumetrics, filter
flasks, a few new 600 ml beakers (Aldrich brand), and so much more. I have enough amino acid derivitives to synthesize an entire persons protein
content... Lots of Fmoc amino acdis, including non-natural ones. But we are making great progress in cleaning out the lab, and getting it ready to
rent to another small company.
