laboratory glass filter holder
A laboratory glass filter holder is an essential piece of equipment designed for efficient filtration processes in scientific settings. This precision-engineered device consists of two main components: a funnel top and a base, both crafted from high-quality borosilicate glass for superior chemical resistance and durability. The holder features a fritted glass disc or membrane support that securely holds filter papers or membranes in place during filtration procedures. The design incorporates ground glass joints that create an airtight seal, ensuring optimal vacuum filtration performance. These holders typically accommodate various filter sizes, from 25mm to 90mm in diameter, making them versatile for different laboratory applications. The transparent glass construction allows for clear visualization of the filtration process, enabling researchers to monitor progress and identify any potential issues immediately. Most models include side arms for vacuum connection and convenient filter paper removal features. The apparatus is specifically designed to withstand both pressure and vacuum conditions, making it suitable for both gravity and forced filtration methods. Its chemical-resistant properties make it ideal for use with various solvents and solutions commonly used in laboratory procedures, while its autoclavable nature ensures proper sterilization between uses. The precision-engineered design minimizes sample loss and cross-contamination, making it an indispensable tool in analytical chemistry, biochemistry, and environmental testing applications.
