Grade 304: is a medium-filtering qualitative paper suitable for a broad range of laboratory tasks. It is ideal for clarifying liquids and rapidly filtering coarser precipitates such as lead sulfate, lead chromate, calcium oxalate, calcium carbonate, aluminium phosphate, barium carbonate, and beryllium hydroxide. This grade is also used in soil analysis, seed testing, air pollution monitoring (for collecting dust-laden air), and in the food industry to separate foodstuffs from extracting liquids.

Application: Coarse Precipitate Filtration, Soil and Seed Testing, Food Separation, Air Pollution Monitoring

Key Features

Qualitative Analysis: Suitable for a wide range of identification and clarification procedures.
