Whatman is a well known brand in the laboratory. Whatman filter papers, chromatography papers and membrane filters are used by many for doing basic separations. This includes high school students testing for contaminants in pond water to rail road technicians analyzing oil viscosity in train brake fluids.

Applications

• Basic lab work - when performing quantitative tests, such as determining total dissolved solids, a sample is filtered using Whatman filter paper and the total dissolved solids is determined gravimetrically.
• The quality of asphalt is determined by spotting a mixture of asphalt dissolved in a solvent and observing the colour of the spot.
• Whatman Benchkote™ is used to cover lab work benches to absorb quickly hazardous spills.
