Thread: Defective Millipore Stericup?

Once again... Thanks so much for all the input. This is an fun yet frustrating process. I have a lot to learn and I'm eager to do so.

Maybe that would speed up the process a little in case the issue is this stuff I have is so dirty it's clogging the .22 millipore up too quickly.

I use the .45, haven't had any issues. Nope no cracks, knock on wood, in the plastic receiver. Just keep the psi under 15, with the .45 it goes fast enough you can filter you whole solution within a half hour. Mines been crystal clear as well.

Ok. I'll try the AutoFill next time for sure and see I that makes a difference. Thanks again!

Ok. Thanks. I've never heard of those... I just did a Google search. They don't look much different than the Millipore... Is it just better quality and less likely to leak?

Absolutely. No leaking at all

Sweet. I'll give them a go next time. I bought two Autofills this morning as per Enrod's advice... So I'm now up to $135 just in filters for this one 400ml batch of Test. Haha.

That's unfortunate sir lol. Good luck

I just went through two millipore duracup pvdf bottletop filters they would not hold vacuum

Yeah... I have more in filters than I do the powder. Haha. But thanks for the input. I will NOT be buying millipore again.
