I have a few more items that I have found recently:

1000 ml amber wide mouth HDPE Nalgene bottles - brand new - These sell elsewhere for $10 apiece but I have 2 packages of 6 that I will sell for $2 per bottle or $10 per package of 6 (plus postage). See below

http://www.shopping.com/nalgene-nalgene-amber-bottle-wide-mo... or
http://www.amazon.com/dp/B003OBYV70/ref=biss_dp_t_asn

I also have some white plastic containers with black phenolic screw tops, they are also HDPE, about 40 oz, diameter is 80 mm, height is 130 mm. I would sell these for $2 each. I believe that they were intended to be secondary containment for shipping small chemical bottles. But they are great for solids, powders, holding septa or other small parts, nails, screws, etc. They should be OK for liquids, but they are not ideal for them. I have a few dozen of these.

I am now out of most 24/40 single joint rbfs, still have a few evaporating flasks and a few 3 necks in 24/40. I have one or two coil condensers left in 24/40, for $25, which I recently found, some addition funnels, and lots of odd adapters, but running out of much in 24/40.

I do still have a number of 14/20 flasks and pieces, which I just updated the inventory of, so if you are interested in 14/20, this is the time to act, as I am just starting to run out of those in a few larger sizes. But I am out of most of the adapters and condensers needed for a complete kit. I do still have some adapters and more esoteric pieces. If people want to buy multiples of one flask or a mix of many flasks, I am very willing to make deals.

I am also running out of crystallizing dishes and beakers, but still have lots of filter flasks, smaller erlenmeyers, and much more. Please see the attached file for the most current list.

Here are most of the rings I have left, from about 2" to 7". They are $5 each.

My feedback on Dr.Bob: I've made several purchases with him, and I've got to say, I'm impressed. Not only did he put extra stuff in every shipment, but he replaced several items for free when they arrived broken! I'm definitely buying from him again in the future.

I am not sure if the Nalgene bottles are autoclavable. I have a few varieties, most of these are made of polypropylene, PP. If the Nalgene site says that there standard Boston round PP bottles are autoclavable, then I would expect all of these to be as well. If you know that some types are autoclavable, I can try to find those types in my collection or find a comparable one. But I Googled a couple types of bottles I have had and the specs say that they can be autoclaved, with the lid loose (so it does not stick shut, I believe).

AFAIK, you send him the money online via PayPal, and he, upon receiving your payment, dispatches the items in the mail.

I have a number of used bunsen burners and bunsen burner tripods as well as mercury thermometers to get rid of. PM me if you are interested.

I am considering to throw away the tripods because they are rusty, the other items can certainly be useful to someone.

I have shipped a number of items to Canada. For packages less than 4 pounds, it is pretty easy, simple customs with no issues so far, and costs about $16-20 for 4 pounds. For packages over that, it gets more expensive per pound until it is over about 10 or 12 pounds, plus there is more paperwork and customs possible issues, although most people have not reported any serious delays (usually under a month).

My main issue is that they are rough on packages during this handling, so that adds to the problem, and there is no practical insurance for international mail, so either I have to charge a little extra for that risk and replace what breaks for free (self insured), which I have done, or you have to accept that some items may break, which I try to avoid.

For example, I had one person who wanted a large order of large fragile items, but wanted to keep the shipping very low, so I tried to pack things in as few boxes as possible to keep the overall costs down, and several items of a large order were broken, due to visibly rough handling (dents in boxes). So I replaced about half of the broken glass for free, but that is not a good option for anyone. So the best solution is to mostly buy smaller things or less fragile stuff, as they are easy to ship internationally, or be willing to pay to cost for well padded and packed items.

I need to update the list and report, I'll do that this weekend if I can. I have sold a lot of stuff in the lat month, so a few more items are running out.

Hmm, I'll take a look through the list again; there were definitely some items that I was interested in.

I take the previous spreadsheet was the latest up to date stock you still have?

Here is a more recent list. I have run out of a few more items, such as 500 ml grad cyl, 1000 ml 3 necks flasks, and a few crystallizing dishes. But there is still a lot left. Here is the latest list. I also have a couple of Corning PC-320 stirring hotplates I just found that work OK, but are a bit dirty. I am asking $90 for each.

Just found 2 more 2L sep funnels with Teflon stopcocks BUT the drip tips are broken off most or all of the way. They would be $40, due to the damage. Otherwise they are good condition, with stopper and stopcock.

Also just found more new 4 and 8 ml vials in packages of 144, with black phenolic caps with rubber liners.

I also keep finding more small volumetric flasks, I have lots from 2 to 25 ml, and a few larger ones left as well.

Thanks to everyone for their help finding this glassware a home.

I have a bag full of plastic scint vials (maybe about 100), Anyone, make me an offer. I have a few loose glass ones, but I don't think I have any boxes of 100 left, although I am not sure. I do have some other 4 and 6 dram glass vials (16 and 24 ml) left with black phenolic caps, I need to create pricing for them, I just found more, and haven't priced them yet.

Thanks again Dr. Bob! Had another order, probably my 6th, and all I have to say is now is as good of a time to be buying from the guy as ever. Edit - my home lab wouldn't be nearly what it is today without him. Don't be afraid to ask him things that aren't on the list!

Here are some of the fritted funnels I have left. The sizes range from 15 ml to 350 ml (volume of the top part). I have simple funnels, as well as 14/20 and 24/40 jointed ones. The frits are F, M and C. I have most frit porosity types in most sizes and styles, but not all. These photos DO NOT include the larger or longer ones, including the ones meant for chromatography, which I am still trying to organize. I have several more boxes of these available, some of those are dirtier or larger. I also have some smaller buchners, glass frits and other odd pieces, most are listed in the spreadsheet.

Many of these are Chemglass, some are Pyrex, Ace or other US brands. But most are the same dimensions as shown in the Chemglass specs (see below for links). No crappy imported ones. Pricing is in the inventory list spreadsheet.

If you want an assortment of sizes or types, I am willing to give a discount on the prices listed in the spreadsheet based on the number wanted. I even have a couple larger ones still new in the box (for more, of course). If you want better photos, please send me a u2u with an email address that I can send photos to, or email me at craigslistinnc at gmail.com and I will reply with my real email (get too much spam there).

PS, One note, if you have sent me a note, u2u or request, and I have not gotten back, please remind me. The u2u system is hard to find old messages in, and I have dozens of conversations going on, so sometimes I am slow to respond, as well as I have lost some messages sometimes.

Here are some 14/20 items left still. First is a small kit of remaining 14/20 dist adapters, accessories, and flasks. Then I have some still heads, simple medium length condenser head and other bits, a vacuum jacketed dist. head, a smaller head, and a distillation fraction collector (bull type) for 4 flasks. I can add items to the 14/20 kits if someone is interested but I am running out of many items like simple 14/20 condensers. Pricing is thus: kit of 14/20 flasks and adapters - $80 including a short path. The 14/20 still heads are $40 and $50 for the 100 or 250 ml size. The simple medium path is $30, the fritted 14/20 column is $15, the vac jacket dist head is $100, the medium sized head (4th photo) is $60, and the bull type fraction collector is $40 (w/o flasks, or $50 with 4 rb flasks).

Here are some odd flasks that I have left for sale.

a) 2 1000 ml 3 necks with center 34/45 joints and side 24/40 joints. Both are worn a bit, the right one has a chip on the center joint. Right one is $20 left one is $15.

b) 1000 ml rbf w/ 3 29/42 joints - the center joint comes with bonus free 14/20 adapter stuck in it. This would be $10, you might be able to get the joint out, stopper it, or just use it as is.

c & d) 1000 ml FLAT bottom flask with all 24/40 joints. $20 NOT for vacuum use, but might be OK for gentle heating. Not sure what this is ideal for, but nearly new condition. Ace Glass brand. c) shows it sitting on its own d) shows bottom view.

e) 1000 ml 3 neck with all 24/40 joints, vertical joints. In good shape, last 1L 3 neck with all 2/40 joints. Ace glass $20
