any place where i can get beginner chemistry lab supplies? im interested in a starter at home lab with an electrolysis setup.
my background is phys and i wanna get into hobby chemistry bevause it seems fun. any advice would be helpful too.

Universities often sell or auction off old lab equipment once or twice a year. That would be a good place to start. If you want new cutting edge stuff just buy it from the same place Uni's do. If you need glassware try eBay. Just watch out what you buy as you might get the knock and talk form some glownigger worried you're making happy pills.

I bought a cheap Creality printer. Learn some CAD and you can make any plastic equipment. PLA and PETG plastic filaments are cheap as fuck, just check what conditions they tolerate

Simple differential amplifiers for electrical recordings are easy to make. Data acquisition devices are a bit trickier, especially if you need super high sampling frequency. But if lower sampling frequencies are fine, you can make a DAQ board out of ESP / raspberry pi

also, if you're lucky enough to live around a uni with glassblowing, smithing, or ceramics classes for cheap/free, you should take some.

i'm a synthetic chemist and have been trying to develop a supply chain-independent workflow since covid. you'd be surprised how much you can make on your own.

Is Mantis the best microscope for a home lab?

no, what the fuck? i haven't heard of anyone using mantis since... ever.

get a leica dm-series.

I got an oscilloscope for free just by asking my professor.

I want to do simple electrophysiological recordings from plants and fungi. Stick electrodes in thrm, record electrical activity in various conditions

Unis replace computers quite often. They are usually willing to hand these out after all data is wiped. I got a tower pc from 2019 from them, very good CPU and just upgraded the RAM. Going to use it as a measurement PC

my home lab is a set of folding plastic tables with 3 laptops, a crack pipe, several bags of crack, some BIC lighters, a yellow legal pad with blue BIC pens, an AR10, 10 25-rd pmags of .308, a Glock 43x in a holster, a red solo cup full of instant black coffee, and a Mora companion

I'm interested in assessing the wild yeast of my area for brewing potential.
So far I plan to collect numerous samples, brew sample batches, and measure the alcohol content of said sample batches.
Would a hydrometer be accurate enough for this purpose?

You can often get cheap second hand electronic equipment at ham meetings.

Why not also check for cheese making potentials while you have the culture? Award winning cheeses have been made using wild cultures.

Tempting, but that's a little beyond the scope of what I want to do.

I'm really disappointed with this board.


I'm setting up a small scale microscopy lab. Microscope I got from my bio department cleanup. I'm now investigating where to get cheap dyes.

I have a MechE friend who is helping me to make a simple microtome to cut samples.

Stab them and make an effigy to ward off the next one.

absolutely.

i would try to incubate some plates of agar and see if you could isolate your yeast from other airborne microbes or you might end up with a sort of kombucha vinegar product. there tends to be a lot more microbes that convert ethanol to acetaldehyde than sugars to ethanol so it's difficult to get it to end on the alcohol product unless you know what microbes you're working with. even breweries call "wild" yeast fementations something they got pure from whitelabs.

sounds fun tho good luck. first post with an actual gameplan.

My best find of the last year or so - I got a complete high vacuum system consisting of a Pfeiffer turbomolecular pump and controller (like this pic I found), roughing pump, and topped with a mass spectrometer chamber and associated mass spec electronic box on the end. Was at on on site auction and nobody had a clue what it was so I paid all of $15 dollars for the system, was amazed when I asked and it was still available and thought it was sold and won it..very exciting. Not sure what to do with it but could try making vacuum tubes or something..guess fusors are the popular use for these.

At the same auction, picked up a milk crate full of microscopes including a Zeiss WL! The WL was the fanciest classic 50s 60s era Carl Zeiss and the stand is made from solid brass, nuts and you can see the spots of green verdigris where the paint is worn. It needs a little TLC like I need to find a nosepiece etc. but paid $20 for all the microscopes and a pile of lenses.

As I said, an auction in my town. As far as safety goes, the pump spins at high rpm but the blades are thin so worst case it self destructs which would be sad so I'm not testing it until I know it won't be damaged. Turbo is water cooled but they can be run for short duration dry. The first stage low vacuum pump has to work as starting a turbo at atmospheric pressure is bad for it.

Im gonna have access to high voltage DC and a pretty good vacuum soon if all goes well, what are some things to do with these?
