Johnson Test Papers' Grade 50C is a standard grade glass filter found in many environmental applications offering a smaller pore size than 50A (1.2 µm), with a slightly slower filtration speed. The properties of 50C filters are a standard in the determination of liquid scintillation counting and total suspended solids collection in potable water and in industrial waste. In biochemical tests, Grade 50C is suited for cell harvesting and the analysis of carbohydrates.
