Glass Fiber Filters

Glass Fiber Filters

유리 섬유 필터

  • Type A/E meets the requirements for suspended solids testing, as described in Standard Methods for
    the Examination of Water and Wastewater, current edition.
  • Reduces filtration costs and premature clogging when filtering difficult-to-filter or highly
    contaminated solutions.
  • Extends filter life and reduces final filter changes with high capacity prefilters.
  • Eliminates sample contamination. Binder-free borosilicate glass fiber has no added extractables.
  • Filters a wide range of particulate loads and viscous solutions with a selection of filter thicknesses from
    which to choose.
  • Filters with binder offer excellent wet strength for easy handling and filter integrity.

GLA-5000 PVC Membrane Disc Filters

GLA-5000 PVC Membrane Disc Filters

GAL- 5000 PVC 멤브레인 디스크 필터

  • Assures gravimetric stability with low moisture pick-up and low tare weight.
  • Low ash. Provides interference-free silica determinations.
  • 5 μm pore size meets NIOSH and OSHA requirements.
  • 25 and 37 mm sizes are ideal for use in Pall Air Monitoring Cassettes.

And Envirochek HV Sampling Capsules

and Envirochek HV Sampling Capsules

  • Simple to use. No assembly or cleaning of filter holders or elution equipment.
  • Saves time by allowing the processing of multiple samples at the same time.
  • Disposable design eliminates crosscontamination and false positives.
  • Typically greater than 70% recovery of target organisms.
  • Eliminates false negatives with 1 μm pore size membrane for retention of Cryptosporidium and Giardia.
    Envirochek HV capsules are 100% integrity tested.
  • Safer to use. Self-contained capsules mean that the potentially contaminated filter element does not
    need to be handled or cut apart.
  • Capsules are serialized for traceability.

GWV High Capacity Groundwater Sampling Capsules

GWV High Capacity Groundwater Sampling Capsules

  • 75 Metals Analysis Certification is printed on each package.
  • Meets filtration requirements of the U.S. EPA.
  • Available in a variety of pore sizes to meet regional regulatory requirements.
  • Saves time and money. Selfcontained devices reduce the need for costly decontamination and multiple filter change steps associated with reusable filter holders.
  • Ensures rapid filtration. GWV provides five times the filtration area of conventional 142 mm filters.

Groundwater Sampling Capsules And Devices

Groundwater Sampling Capsules and Devices

  • Easiest and most efficient way to meet filtration requirements of the U.S. EPA for 0.45 μm filtration.
  • Self-contained, disposable units eliminate the time and hazards associated with cleaning filter holders.
  • AquaPrep 600 capsule features over four times higher EFA than 142 mm disc filters, reducing the need for
    multiple filter changes during the sampling process and ensuring rapid sample filtration.
  • AquaPrep 600 capsules have Metals Analysis Certification on 48 metals printed on each package.

37 Mm Air Monitoring Cassettes

37 mm Air Monitoring Cassettes

37 mm 에어 모니터링 카세트
