glass filter holder for membrane filters
A glass filter holder for membrane filters is an essential laboratory apparatus designed for precise filtration processes in analytical and research settings. This sophisticated device combines durability with functionality, featuring a borosilicate glass construction that ensures chemical resistance and thermal stability. The holder typically consists of a funnel top, support base, and clamp mechanism that securely holds membrane filters in place during filtration procedures. Its design incorporates a ground glass joint that creates an airtight seal, preventing sample loss and contamination. The holder accommodates various membrane filter sizes, typically ranging from 25mm to 90mm in diameter, making it versatile for different application requirements. One of its key features is the integrated fritted glass support, which provides uniform filtration across the entire membrane surface while preventing damage to delicate filter materials. The transparent glass construction allows for visual monitoring of the filtration process, enabling researchers to ensure proper sample processing and identify any potential issues immediately. Advanced models may include additional features such as vacuum ports, stopcocks for flow control, and graduated markings for volume measurement. This equipment is particularly valuable in applications requiring sterile filtration, particle analysis, water quality testing, and microbiological studies.
