Features
• The most widely used filter paper for routine applications with medium retention and flow rate
• This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids
• Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulphate, calcium oxalate (hot) and calcium carbonate
• In agriculture, it is used for soil analysis and seed testing procedures
• In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations
• In air pollution monitoring, using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity measured photometrically
• For gas detection, the paper is impregnated with a chromogenic reagent and colour formation quantified by optical reflectance
• Qualitative Filters: Used for qualitative analytical techniques to determine and identify materials. Grade 1 has a medium retention for soil analysis and seed testing procedures, food industry testing, air pollution monitoring and gas retention. Grade 4 has a high flow rate with good retention of larger particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide.
