Laboratory filters in detail

Design of the laboratory filters


LAB 60 and LAB 140

  • The sealing technique with a clamp lock and gasket ensures a hermetic seal to the outside. This increases the operating pressure to 10 bar.
  • Filters and filter parts are compatible. Depending on the requirements, a sheet filter can be converted into a membrane sheet filter, membrane filter, infusion filter, double filter with infusion chamber and into a combination filter.
  • Equipped with an oscillating piston pump for pumping low-viscosity media. Due to the integration of a pump and drive, the pump is extremely small and has no shaft seal.



  • this laboratory filter was developed for the special requirements of the pharmaceutical industry, for filtration of small volumes in the laboratory or pilot scale
  • can also be used in the chemical and cosmetic industries, as well as for biotechnological applications
  • consists of two vertically arranged circular filter elements, to the left and right of a trub chamber
