Reviews

GD/X™ range is specifically designed for high particulate loaded samples. Constructed of a pigment-free polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media, these filters eliminate sample contamination and allow you to filter even the most difficult samples with less hand pressure. GD/X syringe filters can process three to seven times more sample volume than standard syringe filters.

GMF 150 and GF/F are produced from 100% borosilicate glass microfiber. The innovative, graded density GMF 150 medium has a coarse top layer meshed with a fine bottom layer that retains particles to 1.0 µm. A GF/F filter then retains particles down to 0.7 µm. The prefilter stack ends with a final membrane.

GD/X filter construction facilitates exceptional loading capacity with fast flow rates. This prevents the build up of back pressure typically caused by the blocking of an unprotected membrane.

  • 13 or 25 mm diameter syringe filters
  • 25 mm devices for samples greater than 10 ml (however, the volume of sample that can be filtered through each filter depends on the characteristics of the sample)
  • Sterile options
  • Pigment-free polypropylene housing
  • Unique prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media

Benefits

  • Eliminates sample contamination
  • Requires less hand pressure, even with the most difficult samples
  • Processes three to seven times more sample volume

Applications

GD/X syringe filters are ideal for heavily particulate-laden samples found in;

  • Dissolution testing
  • Content uniformity
  • Concentration analysis
  • Routine sample preparation
  • Food analysis
  • Environmental samples
  • Composite assays
