buy some whatman fast caps! I just filtered 332 mls of 300mg/ml test E in 5 minutes, NO SHIT! I have a vacuum pump that keeps a steady 25 in/hg pressure, I have never seen gear filter so fast, temp was about 65* C, I have had the filters for a while, this was just the first time I've used on. They say that the filter has a life of 10 L, thats a lotta gear for one filter membrane! They're not cheap, I think they're about 25-30$ a pop, but so worth it!

Good info bro,
I only push like 100ml through a syringe filter and they are like $5 each, so that's worth it

If you're referring to the "zap caps", yes they are bad ass! After some guys here turned me on to them, I will never leave them. Little rough to seal, but they are great.
Can't remember exactly how much, but I think even whatman states you can reuse the filter 3x as long as it remains moist.
Zap Caps are superior in my opinion. They are also designed for our application, being "chemical resistant". If you have a nice flask, its amazing how well they seal without being a screw on unit.
I put the wrong name in there guys, yes I use zap caps that are "chemical resistant" to filter my compounds made with EO, but for non EO based compounds, nalgene Fast Caps are the bomb, I put the wrong manufacturer on the original post, they can filer 5 litres before replacing. Theres no need to pour the oil out of your mixing beaker or anything, they come with a draw tube that you drop to the bottom on the beaker, and it sucks it right through the beaker. If I guy has a vacuum pump, you can daisy chain these things too and filter mutiple batched at the same time, just T off you suction to another filter! I HIGHLY suggest you guys give these a shot.

Wish I would have seen this 3 weeks ago lol, didn't quite understand how these worked so I found some instructions.

the one on medlab supply cost way too much for a pump that doesn't let you control the speed of the pump. you can find a good speed control varistaltic pump on ebay pretty cheap.
I got a pump on ebay for 100$, got all the tubing from us plactics, and the npt barb fittings ate ace hardware.
So will those 25$ fast caps filter more than 5-6 standard syringe filters which comes to around the same price?
How much oil will u get throught 1 dast cap?
I have a few 100ml batches to so, was going to use 500ml zap caps but I'm thinking its a waste of the filter if there built for 500mls,
And I want the best value for my cash,
So will fast caps be better that standard nylon syringe filters, 'cost wise'

All I know is the nalgenes with a vacuum pump will filter 600ml of teste in about 45 mins under 25 inches of vaccum, thats fast enough for me to justify the money on the filter, plus zero effort.
Ok cool, so the fast cap is vaccumed to the glass flask below but what goes above to hold the oil in? Or do you just attach a 50ml syringe and let it suck it out?
The fastcap sits on top of ur media bottle of flask one tube runs to ur pump of choice and other tube u attach to fast cal runs into whatever container is holding ur fluids apply pressure of choice and it turns on like champ when u finish jst put it in a ziplock or something until your gonna use it again and it will hold the moisture or at least thats what ive heard that works

Ah right cool, so you can just set the pressure and iit will start pumping automaticly through the tubing, so you could just hold the end over your 10ml vials and mover it over 1 after the other till they have filled up in a line.
look into the polycap AS if you want to see 1000ml go thru it in a couple of minutes. it will blow your mind.
$$$ though.

Also can the unfiltered flask and the filtered flask or vials be on the same bench top level or does gravity play any part in it at all?
Also so there 3 tubes, 1 connected to pump, 1 goes down to the bottom of the unfiltered homebrew and 1 were the filtered homebrew comes out of to either go in another single container or to fill up multi vials etc.
