and to anyone else, is there a supplier, not ebay or amazon, that would sell what Im looking for for cheaper.
Thanks.
| For a few dollars more why not simply buy a Organic chemistry kit From Laboy? I own a set and the glass
is good. The flasks are excellent and the seals are actually well made. here is a link to the kit but if you want just a distilling setup simply buy
each part that you need. Be warned from the date of invoice it will be 2 weeks until they ship. If you want it to come faster put it in the notes
section when you fill out your order. Link to Org. Chem. Kit http://www.laboyglass.com/list.asp?id=5306

Acquisition of apparatus
Dr.Bob is it possible for you to ship any of the glassware and other equipment to Jamaica or are you restricted to the United States? If possible I'd
like to see what I could purchase. ![:D](./images/smilies/biggrin.gif)
Thank You.....

I can ship most anywhere, I mostly use international first class mail up to 4 pounds. Things over that are more expensive (per pound) typically, and
can be more of a customs pain, but can be done.
For example, Canada is about $18 for 4 pounds, up to Aust. at $35. for 4 pounds.
PS. This weeks finds are plastic petri dishes, glass square bottles (~8 oz) with Teflon lined lids, pasteur pipettes (short and long), and rubber
pipette bulbs (2 ml) for use with Pasteur pipettes. I will try to get them listed in the list shortly with prices, and re-post a more current list.
I also found a few more Teflon stopcock Sep. funnels ( up to 2L) for people who have been asking me about them.

Totally awesome, finally I've found someone that can ship to Jamaica. Please if it is possible, create a .doc,
.docx or .xls link consisting of your current stock of equipment. It would be greatly appreciated. ![:cool:](./images/smilies/cool.gif)

Here is the latest list of glassware available. I found a few more 1000 ml erlenmeyer flasks, a couple of 1000 ml beakers, and some more mint
condition Sep. funnels. Also still have a few hotplates, stirplates, and stirring hotplates left.
Out of media and reagent bottles other than 1000 ml and larger now. Running out of full distillation kits, but still haev many pieces as well as
more esoteric adapters and flasks. I still have lots of 14/20 flasks in almost all sizes under 250 ml- 1, 2, and 3 necks included.

I just got some glass from Dr. Bob. Very legit seller. Very pleased with the purchase.
Some rambling now,.. I think itd be nice if there were some way to set up a feedback system like they do with ebay. Itd be nice to have a trade forum
here.
There are probably quite a few people would benefit from it and it would open up alot of people to chems/glassware they normally wouldnt be able to
get, and help others get rid of excess stuff they might not want to sell on ebay(and get buggered by the high fees)
Enough ramblings..
Thanks Bob
Cheers

condition larger Sep. funnels. Also still have a few hotplates, stirplates, and stirring hotplates left. Also found a few 2 and 3 L rbfs with
various single and triple necks in 24/40, 29/42, and larger necks. I also have more disposable Pasteur pipettes in 5" and 9" sizes, $10 per pack of
~250, with a free rubber bulb while supplies last (I just found more, if you bought these before I will give you a few with any other purchase.)
Also have some 4, 8, and 16 ml vials with caps left.
I still have lots of 14/20 flasks in almost all sizes and styles under 250 ml - 1, 2, and 3 necks included. Also some Kjeldahl flasks in 300, 500,
and 800 ml size if anyone uses those.
http://www.amazon.com/Kimble-Kontes-KIMAX-Kjeldahl-Flasks/dp...
Also, I found 12 Apothecary Flasks, in 2 oz/50 ml size. I will take offers on them, but I also put some of them them on Ebay as well:

If anyone is interested in glassware, just left click on my name and select "Send u2u" and send me a note, and I will reply as soon as I can. Since
I cannot send attachments in u2us, please include an email address if you would like photos, lists, or other files, and I will send you an email back
with those.
Note, I also have found some boxes of plastic transfer pipettes, like the ones below, I can sell a bag of ~100 for $5, or a case of 500 for $20.
They hold up to 7 ml, but are really best for moving about 1-3 ml per squeeze. These are non=graduated, but I might have a few that are graduated as
well.

Just a note to let people know that I will be on a work trip/ vacation for a little while, so don't be surprised if i am slow to return messages and
email. I have shipped all paid orders now, but please be aware that I won't have good access while traveling. But I will answer messages once I
return.
Thanks to everyone for your help with cleaning out my garage/basement/attic/etc of glassware. I have made a sizable dent in the pile of boxes so
that I can get to most of them now. I few more and I might be able to move around in my garage again. :-)

I have been back a little while, but am finally catching up with things. If you are interested in anything, please send me a u2u with a real email
in it if possible, as the u2u system is not very easy to keep up with dozens of people at once. I'll send back an email. That also lets me send
photos and excel lists.
I just found a few more small (50 and 100 ml) beakers, still have lots of 2 L grad cyls, and lots of filter flasks, Buchners up to 250 mm, and lots of
14/20 glass frit funnels. I only have a few vol. flasks left. I also found a few more 24/40 long path (~12") dist. heads, complete with
condensers.
Thanks to everyone who has helped me and my friend find a new home for some glassware.

More praise for Dr. Bob
I just received my shipment a few days ago, and I must say I am very pleased. Chemglass flasks for dirt cheap, among other tidbits, all in good
condition and well swaddled in bubble wrap and foam. Shipping was was prompt, and above all, communication was excellent. I highly recommend
purchasing from him. Thank you again sir.

Here is another more unusual item I have 8 of, Baffled Delong Erlenmeyer Shaker Flasks, in sizes from 125 ml to 2000 ml. Some are Pyrex, some are
other brands, all borosilicate glass designed for being sterilized in an autoclave. I have attached a link to a description of their uses, as well
as attach a photo below. I would love to sell all 8 flasks as a lot, along with the 4 metal caps that I have, for $100 or the best offer I get, plus
postage, which would about 10 pounds or about $12-16 by parcel post. But I am open to selling individual ones as well.

Here are some more biochemistry related items. These are designed for filtering solutions through membrane filters which come in several types and
media. I don't have any of the filters currently, but they are easy to find. They have a glass frit which supports the filter. They are often
used with very fine filters for purifying water for HPLC and biochemical processes. I have a variety of pieces, which can be mixed and matched to
some degree, and the more pieces that some one wants, the better deal I would make. If you wanted a mix of small and large tops, I can do that. I
have more tops than bottom adapters, so I will gladly give a small and large top for any version for only a small amount more.
I would ask $40, $50, $35, and $45 for these from left to right.

I checked the inventory list, intrigued by the fritted funnels. Are they the conical shape or are they the buchner shape? Any chance you have a
buchner shaped one 5cm diameter and if so how tall is the filtering part from the frit? I'm looking for 10cm of height or more above the frit.
(like this)

I have scads of glass frit funnels, mostly like the photo shown, just haven't had to time to catalogue them well, as well as some are cleaner than
others, so hard to describe and price. I have some brand new, some very good, and some dirty which I would sell for cheap. I also have some with
the 14/20 or 24/40 joint at the bottom with vacuum inlet for filtering directly into a jointed flask.
Most of the frits are Chemglass as shown, or come in similar sizes as Chemglass. They make them in 15, 60, 150, and larger ml sizes. The 60 ml frit
has a frit diameter of 40mm, and the rim is 50 mm above the frit, while the 150 ml has a 60 mm dia. frit and about 60 mm of height above the frit. I
do have some larger dia. frits with taller sides, most of those may has been made as short silica gel plug columns. If you look at the Chemglass web
page (see below) and see about what sizes and frit porosities you are interested in, I can look to see what I have in that rough size range. One day
when I catch up with things (like that will ever happen) I want to make a list of what frits I have and take some photos to post. But I really do
have a large variety and likely have something that is close to what you want, just have to see what condition.
http://www.chemglass.com/product_view.asp?pnr=CG-1402
http://www.chemglass.com/product_view.asp?pnr=CG-1402-L
(taller ones in a few sizes)
Smaerd, I'll look for one that is that tall and post if I have one or not, I likely have something like that, but it may be wider dia. frit than 50mm.

A little wider or a little skinnier is fine with me as long as its at least 4cm in diameter the height it pretty important if it's taller that is more
than fine. Thanks for the quick reply.

Eh, didn't mean to post yet.....,
<AND items listed as (some chips or Used) were much better than I expected, and he even threw in a few little extra's (extra Keck clamp, rubber
adapter for one of the buchner funnels), etc.
Not that this will happen with every order for everyone, but it was a nice bonus.
If you haven't yet looked at what Dr. Bob has to offer, and need very high quality glassware (Kimax, Pyrex, Etc.) at prices you can't steal this stuff
for, check out the .xml list on this thread.

I also have a number of polypropylene centrifuge tubes, in several types and sizes, 1-2 ml, 15 ml, 50 ml, and maybe some others, and few brands,
including Eppendorf and cyro type tubes, even in multiple colors... While these are mostly used for biochemistry, they are great for some other
uses, I used to often use them for precipitating organic compounds in, since the conical bottom was easy to decant liquids from and then dry the tubes
in vacuum to produce a dry compound. The polypropylene is resist to most organic solvents and aqueous acids/bases for normal usage. (You obviously
cannot heat these or store really aggressive chemicals (eg, Bromine, which reacts with the remaining double bonds in the polymer...) in them long
term.)
I don't have a firm pricing, but I am happy to give free samples of these with other orders, and my goal is to get rid of them, so I am happy to
provide a low price or entertain offers. I will eventually photograph them, list them in the spreadsheet and price them, but I just wanted to throw
this out for people who might want some cheap containers before I do that.
Examples are similar to these:

Received my order from Dr. Bob in a timely fashion, or would have if not for the hurricane shutting down the postal service for over a week. But
everything was there, safely packed, plus some extras, and I am a very happy camper.
