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.

Popular Products

The glass filter holder for membrane filters offers numerous advantages that make it an indispensable tool in laboratory settings. First and foremost, its borosilicate glass construction provides exceptional chemical resistance, allowing it to handle a wide range of solvents and aggressive chemicals without degradation or contamination of samples. The transparency of glass enables real-time monitoring of the filtration process, helping users identify and address any issues immediately. Unlike plastic alternatives, glass holders can be thoroughly cleaned and sterilized through various methods, including autoclaving, ensuring complete removal of contaminants between uses. The precise engineering of the ground glass joints creates reliable vacuum seals that maintain consistent filtration pressure and prevent sample loss. The durability of glass construction means these holders can withstand repeated use and sterilization cycles, making them a cost-effective long-term investment for laboratories. The versatile design accommodates different filter sizes and types, eliminating the need for multiple specialized holders. The integrated fritted glass support provides uniform sample distribution and prevents membrane damage, ensuring accurate and reproducible results. The smooth interior surfaces prevent sample adhesion and make cleaning easier, while the chemical inertness of glass eliminates the risk of leaching or sample contamination. Additionally, the ability to autoclave these holders makes them ideal for applications requiring sterile conditions, such as microbiological testing or pharmaceutical research. The robust construction also allows for use with vacuum filtration systems, significantly increasing processing speed and efficiency.
