Laboratory Vacuum Filtration Pump for USA Market

I needed a Purewick system for my bedridden wife, but I didnt have $700 for a purewick system. I bought a $120 pump and a collection container with this pump as a backup. The $120 pump was loud and didnt work well, so I tried this one I had as a backup. Its quiet, just a little hum, and works great!. I bought another one of these as a backup and returned the $120 pump.

My grandma just had knee surgery. We were unwilling to pay almost $700 for the PureWick Urine System especially because the catheters needed are $200 for a pack of 30. We bought the PureWick Accessory Kit for $50, the $200 catheters, & this vacuum pump. It got the job done. I’ll add an update after using it multiple times to determine if it’s good for long term usage.***if you or your loved one has incontinence/upcoming surgery that will limit leg mobility & have Medicare, try to get the Dr to write a prescription for the PureWick to cover the costs. We wished her Dr had more provisions for her post-op care so we’re learning as we go.

Works well, well made.

This item is nowhere near strong enough to do a vacuum filtration. It wont even make a one liter flask pull a suction on your hand.

I bought this to use with the Purewick system and it worked, but one with more suction would be better for that purpose. The suction isn't strong or fast enough to stop leakages. I am sure it is a great product for the intended purpose. It ran continuosly for a 3 months. Wasn't needed after that so not sure how long it would have lasted.

It's a cheap vacuum pump - the pull is very weak. If you want more pull, spend more money.

I'm glad to write this review so I can set some things straight. I am using this pump with a Buchner funnel and sieving material suspended in water or a water like solution. I am using 15 micron hydrophilic paper filters. For purposes like this, it seems to work just fine. A gravity completion of sieving which took 5-10 mins in some cases, now with vacuum assist takes about 8 seconds.*** NOTE: I know there is an audience out there which wants to use vacuum assisted pumps for doing cannabis related distillations or oil drawing through a filter or similar. Point being - this kind of pump works well for assisting highly viscous liquids like "water" or similar through filtration. If you're looking to pull "oil" or heavy thick liquids through filtration, this likely will not get the job done. Thats what they make $300+ vacuum assist pumps for.

This pump has a very weak ultimate vacuum of about 80 kpa absolute. It's not useful even for filtration.
