I bought a small vacuum chamber from Amazon.
ABLAZE 1.5 Gallon Gal Vacuum... https://www.amazon.com/dp/B01A359IU4?ref=ppx_pop_mob_ap_share
Also got the vacuum pump they recommend in the "often bought together"; you don't need the adapter that is recommended there though. I use it to degas my silicone for molds and just to pull any big bubbles once I pour resin so I know the mold is full (do not degas resin, it's bad news bears).

And I got the 5gal pressure pot from Harbor Freight which you see recommended a lot. Also got a small, oil-free airbrush compressor there that auto stops at 58psi as the recommended Max for the pot is 60. With it, make sure you get shut off valves and an adapter that will fit the compressor hose. An employee can help! If you don't have a harbor freight locally, I recommend calling their services department instead of trying to navigate their website. Make sure to get good thread sealant to stop air leaks at all the junctions; I used Loctite red and coated both the female and male threads before tightening. I also recommend a couple of small c clamps as the lid doesn't always seal well and you don't know until you're up to 40/50 psi, so they work great to put a little extra pressure on the seal wherever it's letting air out (you'll hear it). Don't over tighten the c clamps as you don't want to warp the lid seal.

PS. Not an expert, just what I've used/learned over the past month of messing with these in my free time.

You really do need to get all these factors right for light colored oil. The colder the initial wash, the cleaner the material, the fresher the material, the quicker the wash... the less necessary filtration will be. That said, if you need to filter it, pouring through a coffee filter doesn't really do much for color.

Take it easy on the AC, it can color your solution a bit red. Use it sparingly just to remove the green.

Freeze everything. If you can run the filter inside a freezer, do it.

-Bentonite catches water soluble stuff like lipids and waxes.

-Activated Carbon bonds to the chlorophyll

-DE/Celite catches the AC which holds onto the chlorophyll, along with other smallest contaminants

-The filter disk retains all this material in the funnel

The one I've been using works great. This one is marketed towards the marijuana industry for making concentrates, but its no different than any other vacuum chamber. The only difference between mine that that one is that I bought that vac chamber alone, and a Robinair 5cfm Pump separately. That first link wasn't an option when I bought it.

My 2 cents.
For the bubbles:
ARKSEN Degassing Vacuum Chamber Epoxy Silicone Resin, 3Gallon, 250mm https://www.amazon.com/dp/B00T6ZRSX2/ref=cm_sw_r_cp_apa_hiCaCbM8TMGHC

Autoclave vs. disposable alternatives: like plastic covering?

This is really intereating. I have never made my own media but use several at work. I'd like to know what u are growing on which media?

Often, when I don't recover an organism I wonder if my media is the limiting factor.

Hard to tell if it's closed or open cell foam. But it's not just the foam itself, if the surface is rough you're likely to get some leakage. If a dog hair or something happens to be across the surface, you'll get leakage. Normally these things are insignificant but with a tiny pump it can become a factor.

You mentioned drawers and doors, but actually I'm not convinced you need the foam edges for that. They are relatively smooth surfaces unless there is some sort of raised or embossed pattern that needs to be conformed around - that's what the foam is great for. Plus drawers/doors are usually painted or lacquered so it cuts down on the surface roughness a bit.

That said, I'm starting to get the picture with the info you added. It would be hard to stick an air compressor on most RC vehicles! So the venturi is probably out. The diaphragm pump will do what you need, as long as you don't need it to be fast and you have a decent seal. Also I did some quick googling, there are a number of pumps like this and this as well. Higher pressure than your diaphragm pump but a little less flowrate. You can always double up on the pumps too.

This one claims ~-12psi @ 0.7 CFM, which should be more than enough to accomplish what you need.

Although the total tubing length will probably be pretty short on an RC vehicle, keep the tube as large as you can. The lower the pressure gets, the larger your tubing needs to be to effectively move air. If you use a tiny tube - even a short one - you can have massive losses of vacuum pressure. So -12psi at the pump becomes -5 psi at the cup. If you only have one cup and there is no leakage this won't be a big issue but it will still take longer to achieve a seal.

At work we use cups from Piab, Festo, SMC, etc... but they're not always easy to source if you have to work through a distributor. Here are a couple sources I found though:

Vacmotion


Piab No idea where you're located, you can find a distributor with easy online ordering if you look for a bit.

Worrd thanks for the info bro, now I'm considering getting a chamber too just to be safe. What you think bout this?

I know it ain’t cheap, but why not use a vacuum chamber?

https://www.amazon.com/dp/B01N11WMX2/ref=cm_sw_r_cp_awdb_t1_0myFDbPDB9AT9

You would effectively increase the pressure in your cans without changing temperature and messing with seal compound.

FWIW, this is a method used for other containers.

u/Indemnity4 · 1 pointr/chemistry

Ammosorb is useless. It's really only useful if you live next to a swamp or abattoir.

You really need to positively ID the NOx, and quantify how much.

A Draegar tube like this will work.

You also need to purchase a hand pump that fits the tubes. You can probably find a cheaper used hand pump on ebay.

Google the Draegar manual and it will explain how to use the pump, how to do the measurement and how to convert the reading into a concentration.

u/chaotictinkering · 1 pointr/turning

I haven’t bought one yet, but I’ve been doing some research into it. Stay away from acrylic lids. Some of the materials you use can damage the plastic. I’m leaning towards this one.

u/soakedcardinal · 1 pointr/AskEngineers

People are talking about "venturi vacuum generators" which can draw up a vacuum using the compressor you have. Eg https://www.amazon.com/dp/B01ENZMBS6/ref=cm_sw_r_sms_apa_i_.ddLDbJNZ2SV8

It seems there is a tradeoff between flow rate and vac pressure so you might be able to find one with a high flowrate. These devices are not as cheap as you would think though . . The price is comparable to an actual vacuum pump. However the biggest advantage is that the venturi doesn't use up or burn off vacuum oil which is stinky and coats everything.

Anybody knows where to buy a small vacuum chamber? Amazon JP offers me expensive industrial ones, and I just need a tiny one for my hobby cast thingies

500ml Vacuum Filter Kit with Hand Pump

But you deserve a mechanical vacuum pump. Don't forget the liquid trap.

I've done a dozen+ extractions with this one no problem

I've been using 2 different ones... a venturi and I purchased a chinese pump with a filter.

https://www.amazon.com/gp/product/B00HU8GKT0/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

The chinese pump works quite well for my needs, it's a tiny table so the low CFM isn't a big deal. The filter because I use it indoors and didn't feel like having to deal with oil spit.

Has anyone here ever purchased/put together a kit like this, to do low temp alcohol boil offs to make N/A beer?

I googled this. Anything else would be way above your paygrade.

http://www.apartmenttherapy.com/steam-hammer-se-5805

If it was me, I would try to pipe in a steam trap, and spend buku bucks dealing with the consequences.

Edit: And then I googled this.

http://www.amazon.com/Barnes-Jones-Angled-Radiator-Steam/dp/B008HQ21GK

If you want to go balls out, throw your damage deposit in the trash, face potential steam burns and other injury, and whatever happens down the line, by all means, go for it.

I've never used them in a residential capacity, so I couldn't speak to what an install would entail. Good hunting, 007.
