Lab Vacuum Filtration Pump - Laboratory Filter Distillation Apparatus Kit for Fast Filtration of Liquids

After using a hand vacuum pump for years picked this up because of the price. Works great with my funnel and set up for refining. Will wait to see how it holds up but for now I’m impressed with how well it performed.

I really wish i never bought this. I dont even think it will suck up baby spit. So useless and its sad cause the lady that it was for needed something like this so bad and this was a dud. Dont waste your money please.

The pump is quiet and pulls moderate vacuum for light work. Provided vinyl tubing is totally worthless. The tubing came folded with dozen kinks in the line and the wall is too thin to withstand even slight vacuum. Result: no vacuum at the working end because the tubing collapses shut. Using decent quality tubing and keeping it short will dampen the pulses and help pull a stronger vacuum. Haven't used it long enough to assess its longevity. Experimented with it as a vacuum source for home "Purewick" system and it seems to pull just enough vacuum to work with 10Ft long line hooked up to 1200cc collection container and a bacterial filter. 5L/Min pumping rate seems a little optimistic, probably based on open circuit air volume. Actual pumping rate for open circuit fluid using vacuum to pull water into a collection container at zero elevation is closer to 2-3 Liters /min.

Works well and pulls a good little vacuum. Just be careful you don't get any moisture trying to travel through the hose.

This product is extremely loud and comes with very limited pieces to connect it I don't see this product lasting very long whether it dies on its own or whether I help it die it's not going to last very long so that's about all I can say

I should have re-ordered another unit I had purchased, which was good and lasted two years. This item is junk, in my opinion. It has no suction, and, it takes forever to get a sample. I would not buy it, and I can not return it because it's way past doing so. Buy almost anything else.

At last, a nice little, inexpensive pump that actually works. Well worth the money

This thing was terrible. It created practically no suction, and yet paradoxically just enough suction to cause the garbage rubber tubing to collapse. How can one product suck so much, yet so little, at the same time?
