Oh yeah, we had an issue once while testing air samples near an industrial site. Turned out the air sampling pump was leaking slightly — total mess. Ever since then, we’ve been way pickier with what we use. Good lab equipment doesn’t have to be fancy, just reliable. We’ve found that platforms like https://gentaur.co.uk/laboratory-equipment/ actually offer a solid mix of stuff for different setups, from portable meters to full-scale analyzers.
