OK, great. I'll keep a look out for it, your kettles look like the best deal going, so you're my next purchase.

I know this is really late, but is there any way I can get in on this discount?

Sorry for the late response guys. So, the centrifuge is actually a lab centrifuge, more specifically a clarifier, for bulk cell culture fluid to be cleaned prior to starting polishing steps in a biotech process. It's a Westfalia CTC. They are pretty expensive, but if you want to try it out...

what size? I have some 10L pyrex carboys

Vigo, I see a hose in the background, is that what feeds yours centrifuge? If so what are you using to pump into it? I was thinking about buying an aquarium pump to feed my system, since my peristaltic isn't really ideal. So you keep talking about light phase, not sure what that is. I can...

Any interest in 10L pyrex carboys?

Ya, it does clear the beer. I mean it's still a dark colored beer so I might have a few feet of visibility in high light with the beer. I'm thinking the next time I try this I am going to use a stronger pump and try to get the flow rate up to 5 L/min. That pump I had hooked up was only 500...

The short answer is I bought a bunch of used lab equipment for my garage. The centrifuge was in the bundle, and never had a use for it till now. So, it's just a toy to play with.

Vigo! So it's actually a clarification system. Back pressure on the light phase? Are you suggesting that I put a little pressure on the pool vessel? I think I figured out my foaming issue though, I think my flow rate is too slow, and I'm not keeping the bowl flooded. I just ran my pump and...

Posted this in general discussion, but maybe I'll get more answers here. I own a small pilot scale process centrifuge. I'm running it right now and I am getting a lot of foam. The foam looks like small bubbles. Do you guys think I'm getting oxygen in it doing the centrifuge, or do you...

So I'm running the centrifuge right now. Below is a pick. I'm doing a recirculation on the beer, but I am getting foam. It's very small bubbles, almost looks like the head of guinness. What do you guys think, am I getting air in the centrifuge, or is it carbonation from the fermentation process?

So I put a bottle in the fridge and it got hazy. I did a little reading, and I was thinking next time I'll put my ferment bottle in the fridge a couple of days before I try to centrifuge. Anybody have any other suggestions?

I guess I forgot to mention, that took about 5 mins to clear a 5 gallon batch. I set the centrifuge on its lowest setting 8000G, I think next time I'll step it up to 12000G. I just threw some sugar in the bottle from the picture to see if the yeast is still in solution.

So this is a picture from the Westfaila site. Basically you pump in the solution into the centrifuge and the solids are thrown against the wall of the bowl, then the liquid is free to flow to the bottom of the centrifuge and that is pumped back up and out as a clear solution

I centrifuged an Orange Hefeweizen just because I could. The beer turned out really clear. Attached is an after picture of the beer. Sorry forgot to take before shots and pictures of the process, but it was really really cool! I'll take more pictures next time.
