Overview:

BOROX Qualitative filter papers are manufactured from high-quality cotton linters, ensuring quality, reproducibility and uniformity. Qualitative filter papers are used for analytical and routine analyses, when no gravimetric analyses are required. A wide range of retention/flow rate combinations matches numerous laboratory applications. These filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Features:

- 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 sulfate, 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 color formation quantified by optical reflectance.
