Argos BPE2250 PES Membrane Sterile Bottle Top Aspirator Vacuum Filtration Unit, 0.22 micrometer Pore Size, 500mL Capacity (Case of 12)

Media bottle is cheap plastic and multiple have cracked.Won’t buy again.

So far I have had to throw two of the units away because they are cracked and it pulls air into the filtration. So I have ultimately only had two units successful out of 4. I’ve used 250 mo with no problems but so far this box is trash.

The flow rate seemed to be fine, but the filter media swallowed up 10cc of product. Thats a substantial manufacturing loss. I was doing a small batch, put 40cc in, only got 30 out. The small neck of the receiver flask makes handling the finished product difficult also.

As was mentioned, the flow rate was a little slow but not too bad. I did a two batches of 100ml each and got about 93ml out of each one so not too bad of a loss.

Horrible product!!!they all broke so easy!!!!!

Poor flow rate and made it China. Tried it based on price. Going back to Autofil by Foxx Life Sciences.
