Picture of centrifuge


I have received a request to post a picture of the centrifuge. Here it is. It attaches to a table by a clamp at the bottom, and accepts four standard 15 mm test tubes.

Probably "are you done with chemistry?" I'm also curious, but figured the question might've been asked elsewhere already and I missed it.

The pumps are this model: https://www.harborfreight.com/25-cfm-vacuum-pump-98076.html
I posted a picture here: https://www.sciencemadness.org/whisper/viewthread.php?tid=83...

They've definitely seen some wear but they still work OK (right now they can get down to about 10 torr). If you buy them it would probably be a good idea to change the oil, in which case they could probably get down to lower pressure.




As below, so above.

Hot plate picture


With AA battery for scale.

The hot plate doesn't look too great cosmetically (it's been seasoned by years of use) but it works just fine (and also stirs).

Sorry, that price is too low. My asking price of $75 is already quite a discount compared to similar models of hot plates with stirring capability.

If you want to discuss this further, I suggest you use U2U.

$75 is an excellent price for that hotplate. If I didn't have one, I'd buy it in a heartbeat.

Is the chromatography column the one you showed in the photographs of your TEMPO synthesis?

Why don't you pack some of the stuff especially the more expensive ones (eg hotplate) with you so you don't need to rebuy them in the future?
