Explore a comprehensive range of quantitative filter papers designed for analytical laboratory filtration, gravimetric analysis, separation, clarification and sample preparation where low ash content is important.
Our quantitative filter paper range from Cytiva includes different grades, filtration speeds, particle retention characteristics and diameters to suit a wide range of analytical filtration requirements. These filter papers are designed for applications where the filtered material may be subjected to further quantitative or gravimetric analysis.
Quantitative filter papers, also known as ashless filter papers, are manufactured to provide very low ash content after ignition. They are commonly used for gravimetric analysis and analytical procedures where the amount of residue remaining after filtration must be minimised.
Different grades provide varying filtration speeds and particle retention characteristics, allowing users to select a suitable filter paper according to the sample properties, particle size and analytical requirements. Selection may also depend on sample volume, required filtration rate and the type of laboratory procedure being performed.
Cytiva quantitative filter papers are available in different grades, diameters, sheet sizes and configurations for use with suitable laboratory funnels, filtration assemblies and equipment. Their low ash characteristics make them suitable for analytical procedures where filter residue could affect the accuracy of the final determination.
Quantitative filter papers provide practical solutions for separating precipitates and suspended solids from liquids before gravimetric determination. They can also be used for sample preparation and other analytical filtration procedures where controlled particle retention and low residual ash are required.
Suitable for research and development laboratories, universities and educational institutions, pharmaceutical and healthcare facilities, food and beverage laboratories, chemical laboratories, environmental laboratories, industrial laboratories and quality control departments.
Whether carrying out gravimetric analysis, quantitative precipitation procedures, analytical filtration or sample preparation, quantitative filter papers provide specialised filtration media for laboratory applications where low ash content and consistent filtration performance are important.
