Speciality devices
> Filter tubes
Filter tubes
Versatile Whatman Filter Tubes are designed to prepare and filter samples in batches using standard SPE vacuum manifolds and automated systems. The devices feature a rigid pigment-free polypropylene housing, a filter support and a choice of filter media. 

 

The polypropylene housing is autoclavable for repeated use and ensures excellent chemical and biomolecule compatibility with minimum extractables. The filter media is securely welded into the tube to ensure that the filter cannot be bypassed and no sample is lost.

Filter Tubes are available with 1PS filters and PTFE membranes for chemical compatibility with solvents. The 1PS Filter Tube contains Whatman Phase Separator filter media and is ideal for the quick and easy separation of solvent and aqueous phase layers.

Features and Benefits
 

  • 6, 12 and 60 mL tube capacities
  • Autoclavable, saving time and money in the laboratory
  • Wide solvent compatibility is ideal for combinatorial chemistry applications

Applications

  • Sample preparation and clean-up
