Description of Glass Filter Pump: A glass filter pump is a laboratory filtration apparatus used for vacuum or pressure-driven filtration of liquids and solutions. Typically made from borosilicate glass for chemical resistance, durability, and visibility during filtration. The design includes a glass funnel/filter holder assembly connected to a vacuum flask or reservoir, with vacuum hose connections. The pump mechanism creates reduced pressure to pull liquid through a filter membrane, separating solids from liquids efficiently. Commonly used for sterilization, clarification, particulate removal, microbiological tests, and sample preparation. Features often include a fritted glass filter base, adjustable vacuum control, and precise vacuum gauges. Glass filter pumps are resistant to most solvents and chemicals and can be sterilized by autoclaving, flaming, or dry heat. The apparatus supports filter membranes of standard diameters (e.g., 47mm), suitable for various pore sizes depending on filtration requirements.
