Laboratory Products - Qualitative Paper Filters

Qualitative Paper Filters

Qualitative Filters are used for general laboratory applications which identify or separate precipitates or other particulate matter from a mixture.

  • QL1. (Whatman Eqv. 4) Very fast flow rate, general purpose filter. Suitable for gas filtration, air pollution analysis, retention of large crystalline particles and gelatinous precipitates such as ferric and aluminium hydroxide. Also useful for cleanup of biological fluids and organic extracts.
  • QL2. (Whatman Eqv. 1) Fast flow rate, general purpose filter. Frequently used for clarifying fluids. Also suitable for pollution analysis and retention of medium crystalline particulates such as lead sulfate, calcium carbonate and hot calcium oxalate.
  • QL232. (Whatman Eqv. 6) Medium to slow flow rate, general purpose filter. Suitable as a media to hold soil nutrients in plant growth studies.
  • QL131.(Whatman Eqv. 3) Slow flow rate, general purpose filter. High retention of fine particles and crystalline precipitates such as barium sulfate. Suitable for clarifying cloudy suspensions and boiler water analysis.
