Cytiva Whatman™ Grade 1 Qualitative Filter Papers

Description

The most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. The standard grade cellulose filter papers for medium flow rates.

• Used in qualitative analytical techniques to determine and identify materials
• The most widely used filter paper for routine applications with medium retention and flow rate
• Grade 1 covers a wide range of laboratory applications and is frequently used for clarifying liquids
• Used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate
• Agriculture: Used for soil analysis and seed testing procedures
• Food Industry: Used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid. Widely used in education for teaching simple qualitative analytical separations
• Air Pollution Monitoring: Using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity measured photometrically
• Gas Detection: Paper is impregnated with a chromogenic reagent and color formation quantified by optical reflectance
