LAB FISH Laboratory Vacuum Pump Portable Oilless Diaphragm Vacuum Filtration 30L/min with Rubber Tube Positive and Negative Pressure,110V-220V

I love this pump. It is small, light weight, but very powerful. Very simple to operate.

I’ve been using a $40 diaphragm pump also from Amazon that pushes about 15 PSI but is in the 80-90 db range. This one is pulling 19-20 PSI and is under 40 db under load. It also has suction feet for vibration and to keep it from moving around like my cheaper one did. Far superior and the only regret is not getting it to begin with.

I bought this thing 2 years ago and it's still going strong. Seems to be pretty well made for being manufactured in China. Suction is still strong and consistent as well.The ONLY reason that I'm giving this a 4/5 stars is that the hose barb fitting is an odd size for lab use. The fitting is only 5/16" instead of the pretty standard 3/8" barb fitting that most lab flasks use. You will likely need a hose adapter because of this. I bought the thing assuming it was the standard 3/8" since the actual size is nowhere to be found on this page.Other than that, this little pump has been great.

I rarely post reviews, but ...The unit works very well as described. But it came with a broken filter. Their customer service gave me a $10 refund even though they add the filter as a gift with the unit.That in my opinion is going the extra mile, so I recommend this unit and LabFish!

Too expensive for what it is. Instructions were in Chinese.

I have this on the kitchen counter to seal food using zip lock vacuum bags with valve. It's used two or three times a day and has proven to be reliable, convenient, and way faster and much stronger than the small rechargeable pumps that are used for the same purpose. A head of lettuce lasts for a month in the fridge.

I've barely had this thing for 3 months and it just died. Total Chinese crap. Wish I could give it 0 stars

I Vape, so I make my own ejuice flavoring from natural pipe tobacco, so I had to filter the liquid through chemistry equipment. The filters go down to 2 µm, so with a smaller pump it would take me three full days or 72 hours to filter 800 mL. With this pump, I got the task done in 4 hours running through 4 sets of filters. Well worth the extra cost.
