🚀 Elevate Your Physics Game!
The 58810 - 58897 4-2061 Vacuum Pump is a hand-operated device designed for educational purposes, featuring a gauge that measures vacuum levels in both centimeters and inches of mercury. With a robust air displacement capacity of 725mL and a pumping rate of 15mL per stroke, this compact pump (10 x 7 x 2 inches) is ideal for demonstrating fundamental physics principles in a hands-on manner.

ease of use
very easy to use. so much easier to use than getting oit the food saver. sealed the jars first time, did not have to retry several times

squeak
Not really a usable pump. It squeaks and not well made. The worst, I think, is this toy pressure meter. For the amount of pump one could apply to the device, it is inconceivable that the meter would even MOVE. It reads in 100s of mmHg rather than 10s (and even 10s would likely be unreliable with this pump). I regret to give a bad review to any product, but at the same time, I would be remiss not to give my assessment as a scientist. I can't even say it "sucks" because, well, that would imply a negative vacuum application could be effective. HARDLY. It does squeak.

good product
For the price, it worked as expected. I think I will need one with more power though.

Works well but requires effort
Works as advertised but drawing a 750mm vacuum on a small desiccation chamber required at least a few hundred pumps.

Spend more money. You get what you pay for, and I did.
I ordered two of these and both of them fell apart the first time I use them. What an expensive one before that, and it was so heavy I couldn’t use it. Solid metal. Definitely look at the comments and ratings

Broke in pieces after a month
It basically fell apart after less than a month. It cracked, then just fell in pieces.

The Best yet Worthless Vaccum Hand Pump to Trend
Completely didn't hold any vaccum pressure
