Membrane , Cyclopore PC Clear, 5µm 25mm 100/pk, ยี่ห้อ Whatman

รหัสสินค้า : 7062-2513

Cytiva's clear Whatman polycarbonate membrane filters are made from a pure polymeric film that provides exceptional chemical cleanliness during microfiltration, as well as high visibility under the microscope.

• Contaminant free to minimize chemical leaching
• Low tare weight and minimal water adsorption
• Smooth, flat membrane ensures particles remain on the surface for visibility

Cytiva's 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.

Clear membrane filters for microscopic visibility

Dark particles viewed under a microscope are easier to see when they are on a smooth, clear membrane. The translucent nature of Whatman polycarbonate membrane filters from Cytiva makes them suitable for applications that require viewing of dark particles after microfiltration.

Looking for a filter paper, membrane filter, or syringe filter? Let Cytiva help you find the optimal filter for your needs to ensure reliable analysis.

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
