Product Description

Polycarbonate Membranes Filter PC 25 mm 0.4 um

Whatman Cyclopore polycarbonate membranes are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration characteristics of track-etched membranes.

  • Low affinity for stains improves visibility under a microscope
  • Low nonspecific protein binding minimizes sample loss of proteinaceous samples
  • Narrow micropore size distribution and high pore density support rapid surface capture of analyte
  • Negligible absorption and adsorption of filtrate; nonhygroscopic
  • No particle shedding enables clean filtrate
  • Biologically inert


Whatman Cyclopore track-etched membrane filter circles are suitable for a wide variety of applications, from general filtration, including cross-flow filtration (tangential flow filtration), to air and water monitoring, microorganism analysis, and many healthcare applications, including immunodiagnostics.

GE Healthcares Life Sciences business offers a variety of Whatman track-etched membranes. Cyclopore comes in clear and black colors. Nuclepore track-etched membrane options are available for organic halide adsorption, electron microscopy, and other specific applications.

Product Specification:


Cyclopore Polycarbonate Membrane, 0.4 um pore size, 25 mm circle (100 pcs)


Air monitoring: Trace elements (chemicals, radioactivity) and particulate analysis (dust, pollen, and airborne particles) Analytical methods: Gravimetric analysis, densitometry, emission spectroscopy, x-ray fluorescence, and infrared analysis Water analysis: Absorbable organic halides (AOX), direct count of microorganisms,marine biology and dissolved phosphates, nitrates, and ammonia analysis Blood filtration and cell analysis: RBC deformability, leukocyte removal, RBC filtration and plasmapheresis, chemotaxis, cytology, and cell culture General filtration: Particulate and bacteria removal,cross-flow filtration, HPLC sample preparation, and solution filtration Microscopy:Electron microscopy, epifluorescence microscopy,and direct optical microscopy Microorganism analysis: Direct total microbial count,harvesting, concentration, fractionation, yeast, molds, Giardia,Legionella, coliform, and canine microfilaria Nucleic acid studies:Alkaline elution and DNA fragment fractionation Oceanographic studies:Transparent polycarbonate membrane filters provide a new tool for studying planktonic organisms. These ultra-thin transparent membranes are strong yet flexible, allowing for planktonic samples to be filtered and the membranes to be mounted directly onto microscope slides. (Ref: Hewes et al. 1998; Graham and Mitchell 1999; Graham 1999.)Healthcare: Biosensors - as a barrier offering controlled diffusion for biological reagents and electrochemical detectors. Diagnostic assays - for flow control, sample preparation, blood separation, and capture of latex microparticles. Cell biology - for cell culture, chemotaxis, and cytological analyses, e.g., direct staining, isotopic and fluorescence-based assays. Transdermal drug delivery - as an inert matrix for retention of therapeutics
