Product Overview
Whatman Grade GF/A glass microfibre filters are engineered for high-efficiency filtration in laboratory settings. Made from 100% borosilicate glass, these filters provide exceptional chemical resistance and thermal stability, ensuring reliable performance across diverse applications. The GF/A grade features a nominal particle retention of 1.6?m, making it ideal for trapping fine particulates while maintaining a high flow rate. The uniform structure minimizes clogging, allowing for consistent filtration without compromising speed. These filters are widely used in air and liquid monitoring, gravimetric analysis, and sample preparation due to their high loading capacity and low extractables. The absence of binders ensures purity, making them suitable for sensitive analytical procedures. Available in multiple diameters, they fit standard filtration apparatus, offering versatility for various experimental setups. Whether used for routine lab work or specialized research, Whatman GF/A filters deliver precision and durability, making them a trusted choice for scientists and technicians.
FAQs
1. What is the particle retention size of Whatman GF/A filters?
