Filtry membranowe Cyclopore
Membrany poliwęglanowe Cyclopore są membranami o ściśle zdefiniowanych porach z wyraźnymi krawędziami. Swojej strukturze zawdzięczają wysoką odtwarzalność w procesach mikrofiltracji.
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
• 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

We offer 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.

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
