What is Grade 50B?
Johnson Test Papers grade 50B is a very thick filter with fine particle filter and good loading capacity. It offers a smaller pore size than 50A with high wet strength. 50B filters are particularly useful for liquid clarification of suspensions loaded with fine particulates and liquid scintillation counting.
- Nominal pore size of 1.0 µm
- Appropriate for liquid clarification and/or liquid scintillation
50B Fine Particle Filter Benefits
Liquid scintillation counting (LSC) requires a fine particle filter, preferably with a high loading capacity. Grade 50B filters from Johnson Test Papers are ideal for this and similar applications requiring filtration of large volumes such as:
- Membrane pre-filtration
- Quantification of solids
- Waste water analysis
- Liquid clarification for suspended solids analysis
