It pulls a vacuum but is a bit loud, and caulking a pipe into the bucket doesn't seem to be a very durable solution. I'm planning on fitting an airtight lid with hosebarb to it so it can vent gases easily, and I'm considering detaching the pump and using an unmodified bucket. I'm pretty sure I'll have to prime the pump if I do that, though.

I have a vacuum pump, but I can't use it to remove solvents under vacuum, and it's vulnerable to attack by acids, halogens, and so forth.

I just spent $600 on stuff for the lab. Various chemicals, new glassware (most notably a Dean-Stark trap), and something that I've been yearning for for a long time...
A Chemglass PTFE diaphragm vacuum pump!!! :D ;)

It's a used one from eBay and is this model. It's supposed to arrive next week but I was so excited I had to post something now.

Nice. Those diaphragm pumps definitely have their uses.

So I saw this ad on craigslist, (if you don't know what that is, it's a place where everyday people can sell and buy things. Less exclusive than Ebay.) for a 6000ml erlenmeyer flask, two allihn condensers, and a 500ml grad. cylinder. It was a great deal, so I go to pick it up, and the seller decides to add in a handful of test tubes with rubber stops and three quartz glass tubes that he had laying around. And he decides to give it all to me for free.
I have no idea what i'm going to use it all for, but I have it!
The glassware, excluding the quartz glass, is all Pyrex. None of it is ground glass, which is a bit unfortunate, but I'm sure I'll get some use out of this free glassware!
Probably not the right thread, but I'm very excited so I had to share it. :)

I should have put a scale there, If you don't already know the size of some of the stuff it could look smaller than it is. The Erlenmeyer is 6 liter, the grad cylinder is 500ml, and I think the condensers are 400mm.

I got a [very inexpensive] new in box Glas-Col 500 mL heating mantle, with power cord! No longer will I have to mess around with salt baths and oil baths at a 500 mL scale.

Another big plus is that I won't have to endanger myself with this abomination every time I want to use my other heating mantle.

Nice find!
I have a glas-col 500 mL
I got it used off of ebay very inexpensively, and was actually concerned it might contain asbestos. I called them up, it doesn't. :)
Sure beats a sand bath.

I got a PID controller with a big relay. My plan is to wire it up with an oven dimmer and use it to control my various electric heating apparatuses.

I got an infrared temperature sensor. I really ought to pick up a heat gun at some point....

My wonderful EE brother-in-law set up a PID for me. Now I use it to control a cheap toaster-oven. This set-up makes a great drying oven.

Tomorrow my new microscope arrives. This will be my first real microscope. The last one was basically a toy that I had ~65 years ago. I haven't been using up my chemistry budget lately, so this is a Christmas gift, from me to me, with love. I've never studied biology/microbiology yet, but I guess it is never too late to (try) to learn.

I have exactly the same regulator/flowmeter for my Ar tank. Works great! If all goes well, I'll be using it this weekend in combination with my new propane furnace :D (this one) Appears to be good quality but we'll see how the test run goes.

Nice furnace. I wasn't sure if I had the regulator screwed on all the way, but the flare fitting doesn't want to go any tighter even with a fairly large crescent wrench, and I don't want to strip off any threads.

I am going to try playing with some organometallics soon. I am probably going to start with something easy like synthesizing t-butanol from acetone and methylmagnesium iodide.

I dont normally post in this, not even my prized satorius balance!! But i figured i would share this enay score with you....

Now you all know how i like my real books, take a wild guess what i won this lot for in the auction with P&P?
22 books all together. I will post pics of some the highlights for me.

Three of them i already have, so if anyone is interested shout me. One i think is fairly hard to get and costs a fortune normally.

its the last three i have duplicates of now
I think i am now well over 200 hardback books on chemistry and biology
