Filtry z włókna szklanego GF/B, bez lepiszcza
Filtry GF/B są grubymi filtrami o retencji drobnych cząstek oraz wysokim ładunku. Są szczególnie polecane do klaryfikacji płynów oraz w cieczowym liczniku scyntylacyjnym (LSC).
Whatman™'s brand Grade GF/B is a thick filter with fine particle filter and good loading capacity. GF/B filters are particularly useful for liquid clarification and liquid scintillation counting.

• Nominal particle retention of 1.0 µm
• Appropriate for liquid clarification and/or liquid scintillation

We offer a wide range of glass microfiber filters to support your analyses. See the Whatman™ range of glass, binder-free filters to find the thickness and particle retention for your application.

GF/B fine particle filter benefits
Liquid scintillation counting requires a fine particle filter, preferably with a high loading capacity. Grade GF/B filters are ideal for this and similar applications such as waste characterization and liquid clarification for suspended solids analysis.
