Laboratory pressure pumps are something you’ll see in pretty much every lab unit you pay a visit to, no matter its size – this is because the number of applications a simple (but well-designed) pressure pump can have is truly staggering, and many scientists find them to be a highly universal tool.
When it comes to finding high-quality laboratory pressure pumps, you have to consider their sensitivity to molecule size – in other words, how small the material’s molecules have to be before they start escaping the airtight sealing. This is important, because in many cases in your experiments you’ll be sealing gases or liquids with a relatively small molecule size, and considering some of them will be flammable, letting them escape is the last thing you should do.
In addition, laboratory pressure pumps should be able to work both ways if you want to get the most utility – that is, the pump should not just be able to produce a tight, solid vacuum, but also pressurize a vessel to at least some degree. Sometimes you may get a dual-operation pump that actually comprises of two units – this is a trend that’s been catching on lately, and it’s actually surprisingly effective when used right.
