Hi, I am really new, like literally registered to post this post. Besides that point, what do you think would be a good kit for a casual home lab? Mostly dealing with small organic reactions and distillations if anything, but I don't have any glassware so I'm short on that regards. I live in the East Coast so shipment shouldn't be an issue, but if I were to set up an order from you, what do you think would be the best combination of simple glassware for me?

Most people start with simple glassware like beakers, graduated cylinders, flter flask and a buchner funnel, maybe a few erlenmeyer flasks, funnels, and some bottles or vials to store stuff in. They are heat resistant, safe for organics and corrosives, and more accurate than most kitchen measuring cups. But you can use OTC or home items for many tasks, especially if they are messy or non hazardous. You can get a variety of this type of used glassware for $25-100 that covers most things that you might want to start. Some disposables like pipettes, test tubes, and filter paper are also useful, I have some, but not all of those things, and can do small amounts to start you off.

For distillations and more complex reactions, a kit like that shown above is about $100 in used condition (my kits are all older US made, used, but high quality, labware), and then you can add stuff as needed, but it will do a lot, I used almost the same kit in sophomore organic lab. There are also cheap new versions from China and India, some are not bad, some are terrible, and since China subsidized their exports postage, shipping is cheap. Sometimes things are good, some bad, very dependent on the seller. Make sure to use paypal or a credit card so if there is a problem you can make a claim.

But you can get smaller or bigger kits than that for less or more than $100. I like to start simple and get people to buy more stuff if they find they need it, it does not take much to do simple organic reactions. So for $25 - $200 you can pretty much get a basic lab.

Hope that helps, I had more info then my browser crashed, so I will stay shorter this time.

Not sure if I have exactly that, but I am still looking around, it might take a few days to look in the likely places. I know I have had some similar ones somewhere years ago, with a wider top, like a funnel. But it also looks a lot like a larger volumetric pipette that has been cut in half. Not sure how easy to score and snap one, but I could try, then just fire polish the edge. I could try that if you want.

No, please don't bother cutting a pipette. I did find something that will work at Fisher Scientific. It is 45mm wide at the funnel, however, which is much larger than I need. I did order it as it is holding up my synthesis of catechol.

Met with Dr. Bob today! I got some odds and ends but most excited about a new hot plate! The old one was a discard from a local community college and it's gotten unworkably decrepit. I am considering some sort of Viking funeral - take it outside, pile some thermite + magnesium on top, and turn the heat all the way up xD Thanks again!

Here is an udated list of my current hot/stir plates. The Corning ones below (PC models) all have a nominal size of 6 x 8", which has a usable 5" x 7" area on top.

PC-420 - clean - stirs and heats fine - $140
PC-410 - clean - stirrer only - $100
Cimarec - little dirty - heats and stir well - $150 - digital temp readout works - stirrer is a little noisy - nominal size is 8" x 8", usable is 7" by 7" top. The model number is 8P131325. (For a look at similar versions, see https://www.nist.gov/laboratories/tools-instruments/thermo-s... or https://assets.fishersci.com/TFS-Assets/LED/product-images/F... )

I also still have a few broken ones, mostly without cords or with frayed ones, may work or not, hard to tell. If anyone wants to try to fix a few, or salvage them for parts, I am willing to part with a couple for just the cost of packing and shipping them, in return if you can get more than one working, I would be interested in fixing some for sale and splitting the proceeds or getting back one or two working ones as a trade.

Hi Dr. Bob, please check your U2U? Looking for a bump trap, seals, advice.

Thanks!

1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

I have a box or more (100 or 144+) of 1 ml ampules for glass sealing. I can send them in boxes of 10 pretty easily if you just want a few, or I can ship a partial or whole box.

I also have some crimp top ampules, I would have to see which ones I have left, I had some 5, 10, 20 or 25ml ones, can't remember how many of what. They are all 20 mm dia septa. If you know how many of what size you are looking for, I can narrow down my search. I do also have a crimper tool for them as well, was holding it for someone a long time back, but they never bought it.

Bob

Here is an updated copy of the inventory. I have a hard time keeping it updated, but I am trying. Again, for new people, this is a rough list of the glassware I have available for sale. I am out of many things, but keep finding more as I unpack more boxes.

Most of this is used glassware from a long closed chemical company that a friend worked for, his only ending pay and retirement was anything he could carry out within 2 days of the shutdown, which was about 200 boxes of labware. Some is from a few other companies that friends have worked with and also closed. A few items are new, either still in the box from the closed companies or items that I have bartered for with other sellers and a few group buys. I share the proceeds with my friend, he did not have space and time to sell it. 99% of the glassware is US made, high quality glassware from top companies.

If you have any questions on the condition, please ask. I am sometimes slow to answer, as I have a full time job, plus a few part time ones. So I answer questions as fast as I can, and try to ship orders quickly once they are agreed upon, but it can take a little while to get to that point. But I try to make people happy and do fair deals. Thanks to the people that have helped me and my friend make some extra money, recycle some good glassware, and clean out a lot of boxes that we don't have space to store much longer.
