รหัสสินค้า : 7091-4710

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

• Low affinity for stains improves visibility under a microscope
• Negligible absorption and adsorption of filtrate; nonhygroscopic
• Low protein binding minimizes sample loss of proteinaceous samples
• Narrow pore 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

Cytiva's business offers a variety of Whatman PCTE membrane filters for gravimetric analyses. Browse the range of Whatman track-etched membranes to find other Cyclopore membranes and Nuclepore application-specific membranes for organic halide adsorption and electron microscopy.

Track-etched membrane applications

Whatman Cyclopore track-etched membrane filters are appropriate for a wide variety of analytical procedures such as densitometry, gravimetric analysis, and emission spectroscopy.

Application : Air monitoring: Trace elements (chemicals, radioactivity) and particulate analysis (dust, pollens, 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
