Flask Filter

Filter flasks, also known as Buchner flasks, are laboratory glassware designed for vacuum filtration processes. These flasks are made of durable borosilicate glass, allowing them to withstand chemical reactions and high temperatures. Filter flasks are used to separate solids from liquids, commonly during procedures like filtration of precipitates in chemistry experiments. They are equipped with a thick-walled, sturdy design to handle the vacuum pressure applied during filtration, often connected to a vacuum pump or suction source. Filter flasks feature a sidearm for vacuum attachment and a flat bottom for stability. A filter paper or membrane is placed in a funnel, and the liquid is drawn through by suction, leaving the solid particles behind. These flasks are essential tools in laboratories for efficient liquid separation, ensuring purity and clarity in various chemical, biological, and environmental testing applications.
