Filter Flasks 250ml W/Sleeve No. 3
250ml filter flasks with a vacuum sleeve (sidearm) are heavy-walled borosilicate glass containers designed for vacuum filtration, vacuum-assisted distillation, and as safety traps. They are essential for separating solids from liquids quickly using a Buchner funnel and for degassing solutions.
Key Uses and Features
Vacuum Filtration: The primary use is connecting the sidearm to a vacuum pump or aspirator to speed up filtration through a Buchner funnel.
Safety/Vacuum Trap: Positioned between the suction source and the experiment to prevent liquid from being pulled into the pump.
Distillation: Used for collecting distillates in a vacuum distillation setup.
Degassing/Defoaming: Used for removing dissolved gases from liquids.
Durability: Made of high-quality borosilicate 3.3 glass, designed to withstand high pressure changes and thermal shock.
These flasks are essential for laboratory, educational, and chemical processing applications.
