Syringe Filters GD/XP Whatman

Whatman GD/XP Disposable Syringe Filters are designed for use with hard-to-filter samples that require inorganic ion analysis, as levels of ion extractables are minimized.

GD/XP Syringe Filters contain three filtration layers, including a two layer prefilter stack comprised of 20 μm and 5 μm polypropylene filters and a final membrane filtration layer positioned below the prefilter stack.

 

GD/XP Syringe Filters benefits:

  • Increase flow rates and reduce blockage as a result of the two layer prefilter stack
  • Eliminate sample contamination
  • Requires less hand pressure, even for samples with a high level of particulates
  • Process three to seven times more sample volume
  • Reduce costly exchanges with extended filter life

 

Applications

  • HPLC sample preparation
  • Trace metal analysis
  • Sample preparation prior to dissolved heavy metals

 

Characteristics

  • Housing: Polypropylene (pigment-free)
  • Filtration Area: 4.6 cm2
  • Maximum Pressure: 5.2 bar (75 psi)
  • Full Housing: 1.4 ml
  • With Air Purge: 250 μl (approx
  • Dimensions: 20.8 x 30.0 mm
  • Weight: 3 g (approx)
  • Flow Direction: Flow should enter from the inlet
  • Inlet Connection: Female luer lock
  • Outlet Connection: Male luer
  • Sterilization: Autoclave at 121ºC (131ºC max) at 15 psi for 20 min
  • Biosafe: All materials pass USP Class VI
  • Prefiltration Media: PP 20 μm : 5 μm
