WHATMAN PTFE针头滤器6784-2504Puradisc 25 
WHATMAN PTFE针头滤器6784-2504 6784-1302Puradisc? syringe filters combine premium 
quality and economy. They are ideal for the quick, efficient filtration of 
samples up to 100 ml volume.
Puradisc filters are produced from pigment-free polypropylene or polycarbonate 
with standard inlet (female luer lock) and outlet (male luer) connections 
(unless otherwise stated). Options include a sterile, medical-grade blister pack 
for critical applications and a special tube tip outlet that allows the sample 
to be accuray dispensed into a micro-vial, eliminating air lock.
Features and benefits
  Pigment-free polypropylene (polycarbonate for Puradisc 30 and Aqua 30)
  Standard inlet and outlet luer connectors
  Optional sterile, medical-grade blister pack
  Tube-tip format (optional) for accurate dispensing into a micro-vial
  Choice of membrane or glass microfiber filter media
  Choice of filter sizes (4 mm, 13 mm or 30 mm) to minimize sample loss
  Sterile option for critical applications
  Wide range of membranes

Puradisc 4 Syringe FiltersPuradisc 4
Features 
  4 mm diameter syringe filter
  Sample volume up to 2 ml
  Low hold-up volume < 10 μl ensures maximum sample recovery
  Tube-tip format (optional)
Applications
  HPLC samples containing low solid content – filtration will improve column 
life
  CE (Capillary Electrophoresis) samples – filtration will eliminate spurious 
  peaks
  Sterile filtration of low volume samples
  UV/Vis samples – filter directly into cuvette using tube tip
  Refractometry – filter samples to prevent damage to instrument optics and 
  improve accuracy of results
  Minimizing non-specific binding to membrane (due to small membrane size)

Puradisc 30 Syringe FilterPuradisc 30
Features 
  30 mm diameter
  Larger filtration area (44% greater in comparison with 25 mm)
  Designed for aqueous samples
Applications 
  Filtration of protein-containing solutions with minimal protein loss (CA 
  membrane)embrane)
  Removal of cellular constituents from solution
 
Puradisc Aqua 30 
Specifically designed for filtration of environmental samples prior to COD and 
DOC analysis. The membranes used in these devices are prewashed prior to 
assembly so as to reduce the organic carbon level.
