For the lab pros out there: this Kimble Chase flask is designed for large-volume microfiltration. It's a 1000mL borosilicate glass flask with a 40/35 inner joint, made to work with a 90mm filtration assembly (fritted glass support). That makes it ideal for filtering corrosive liquids, samples with lots of particles, or large volumes of HPLC solvents—situations where smaller filters might clog. Borosilicate glass means it can handle thermal shock and chemical exposure. The blue color might help with identification in a busy lab. It's a single flask (sold individually) and is manufactured in the USA. A specialized, high-quality piece of equipment for industrial, research, or advanced analytical laboratories. If you're setting up or replacing filtration gear, this is a solid, reliable component.
