Product Overview
The Whatman Grade GF/B Glass Microfibre Filter is a high-performance filtration solution designed for demanding laboratory applications. Engineered with borosilicate glass microfibers, this filter offers exceptional particle retention down to 1.0 ?m, making it ideal for applications requiring fine particulate removal. The GF/B grade is known for its fast flow rate, ensuring efficient filtration without compromising throughput. Its chemical resistance allows compatibility with a wide range of solvents and reagents, making it versatile for various lab protocols. The filter’s uniform structure and high loading capacity ensure consistent performance, even under heavy particulate loads. Unlike cellulose-based filters, glass microfibre filters provide superior strength and temperature resistance, maintaining integrity during autoclaving or high-temperature processes. The Whatman GF/B filter is widely recognized for its reliability in critical filtration tasks, offering researchers and technicians a dependable tool for achieving precise results. Its low extractables profile minimizes interference in sensitive analyses, while the binder-free composition prevents potential contamination. Available in multiple diameters to fit standard filtration apparatus, this filter provides flexibility for different experimental setups. Whether used for routine sample preparation or specialized applications, the Whatman GF/B delivers consistent performance that meets the rigorous standards of modern laboratories.
FAQs
1. What is the particle retention capacity of Whatman GF/B filters?
Whatman GF/B glass microfibre filters have a nominal particle retention of 1.0 ?m, making them suitable for fine particulate filtration.
2. Can these filters be autoclaved for sterilization?
Yes, Whatman GF/B filters can withstand autoclaving at standard laboratory sterilization temperatures without compromising their structural integrity.
3. Are these filters compatible with organic solvents?
The glass microfibre composition provides excellent chemical resistance, allowing compatibility with most organic solvents and aqueous solutions.
4. How does the flow rate compare to standard cellulose filters?
GF/B filters offer a significantly faster flow rate compared to cellulose filters of similar retention ratings, improving filtration efficiency.
5. What’s the difference between GF/B and other Whatman glass microfibre grades?
GF/B provides a balance between retention and flow rate, with finer retention than GF/A but faster flow than GF/C, making it versatile for general lab use.
