Lab Vacuum Filtration Pumps

It does not have a very powerful suction but it works for what I need and seems good so far. Occasionally the pump stops and I have to power cycle it but it starts back up, not sure what exactly is going on there.

After only two days of usage my pump went dead. I had it connected to a transformer for 110v and even did a reading on the power. On my part I kept the pump safe but the pump itself is poor quality. I had a look inside and found the coil is only wrapped up in rubber tape. I don’t see how this is a “water proof pump” since water leaked into the tape and now my pump is fried. I hap to spend a huge amount of money on shipping it and now that it’s broken I am really disappointed. Don’t buy this item there is no reason you should if you plan on pumping water. For air vacuum it’s fine though.

This pump work perfect it’s small and doesn’t make noise .

When I bought this it was for a project I was working on. About two months later I pulled it out of the box to get to the next step in my project and that's when I found out how poor it was. The vacuum can barely be felt even with the tubing occluded. The little instruction booklet said the on/off switch was on the bottom, it is on the power cord. This is junk thrown in a box. If I tested this when it arrived I would have sent it back.

Bought this to use with the Purewick, works great, just the right amount of suction.

I received this pump today and find that it does not meet the needs if you're trying to use standard size labware connections. I have a vacuum flask that has a 1/2" (13mm for you metric types) and the supplied adapters don't even come close to being able to go over the connector. I checked the vacuum and I was able to measure maybe 10 in/Hg. Don't recommend.

Of the three we’ve used: 2 ceased functioning after a few days, the third actually caught fire and melted. Not only is it a poor quality product, it has proven itself down right dangerous.

Works great and remarkably quiet
