glass membrane filter holder

A glass membrane filter holder is an essential laboratory apparatus designed for precise filtration processes in scientific and industrial applications. This sophisticated device consists of high-quality borosilicate glass components that provide exceptional chemical resistance and durability. The holder typically features a funnel top, support base, and spring-loaded clamp that securely holds filter membranes in place during operation. Its design incorporates a ground glass joint system that ensures an airtight seal, preventing sample contamination and maintaining filtration efficiency. The holder accommodates various membrane filter sizes, typically ranging from 25mm to 90mm in diameter, making it versatile for different application requirements. Advanced models include features such as graduated markings for volume measurement, vacuum ports for pressure filtration, and specialized fritted glass supports that provide uniform flow distribution. The transparent glass construction allows for visual monitoring of the filtration process, enabling operators to ensure proper sample processing and identify any potential issues immediately. These holders are particularly valuable in applications requiring sterile filtration, particle analysis, or the preparation of analytical samples, making them indispensable in pharmaceutical laboratories, environmental testing facilities, and research institutions.

New Product Releases

The glass membrane filter holder offers numerous practical benefits that make it an invaluable tool in laboratory settings. First and foremost, its construction from high-quality borosilicate glass ensures exceptional chemical resistance, allowing for use with a wide range of solvents and aggressive chemicals without risk of contamination or degradation. The transparent nature of glass provides clear visibility throughout the filtration process, enabling technicians to monitor sample flow and identify any potential blockages or irregularities immediately. The holder's robust design incorporates precision-ground glass joints that create reliable, leak-free seals without the need for gaskets or O-rings, reducing maintenance requirements and replacement costs. The versatile configuration accommodates various filter membrane sizes and types, providing flexibility for different experimental protocols and sample volumes. The inclusion of vacuum ports facilitates both gravity and pressure filtration methods, enhancing efficiency and reducing processing time. The holder's autoclavable construction ensures complete sterilization between uses, making it ideal for applications requiring strict aseptic conditions. The spring-loaded clamp mechanism provides consistent pressure distribution across the filter membrane, preventing damage and ensuring uniform filtration. The device's modular design allows for easy disassembly and cleaning, minimizing downtime and maintaining optimal performance. Additionally, the durability of glass construction offers an extended service life compared to plastic alternatives, providing excellent value for laboratory investments while maintaining environmental sustainability through reusability.
