What is Grade 305?
This grade is used for the filtration of coarse particles and gelatinous precipitates such as ferric aluminium and magnesium hydroxides. Grade 305 is used in air monitoring and gas filtration when a high flow rate is needed. This grade is also found in routine cleanup analysis of insoluble liquids such as biological fluids and organic elements.
