Cytiva, 6809-5022, Whatman™ Anodisc™ membrane filter circle with support ring, 0.2 µm, 47 mm (50/Pk)

High pore density and narrow pore size distribution make it an extremely precise membrane. Hydrophilic membrane with wide solvent compatibility, reducing the need to stock a variety of membranes in the laboratory. No additives used in the manufacturing process ensures minimal extractables and no sample contamination. Extremely low protein binding minimizes sample loss. Virtually transparent when wet making it highly suitable for microscopy studies. Non-toxic for cellular growth. Well suited for a wide range of laboratory filtration applications. This novel material has a precise, nondeformable honeycomb pore structure with no lateral crossovers between individual pores, that filters at precisely the stated cut-off, allowing no larger sized particles to pass through the membrane. Anopore™ inorganic membrane is composed of a high-purity alumina matrix that is manufactured electrochemically. The membrane also exhibits low protein binding, is nontoxic, and supports cellular growth. Microorganisms and particulate material are captured on the surface of the membrane for subsequent analysis by light or electron microscopy. When wet, the membrane is virtually transparent, which means that retained particles do not need to be transferred to another surface before microscopic examination. The membrane is hydrophilic and is compatible with most solvents and aqueous material. No monomers, plasticizers, adhesives, surfactants or wetting agents are used in the manufacturing process, which eliminates sample contamination and ensures low protein binding and minimal loss of sample. Can be provided with support ring - The membrane is peripherally bonded to an annular polypropylene ring (except the 13 mm diameter disc) for ease of handling and is suitable for both vacuum and pressure filtration. Anopore™ is available in 3 nominal pore sizes: 0.02 µm, 0.1 µm, and 0.2 µm, and in 3 diameters: 13 mm, 25 mm, and 47 mm. An alternative item number with low fluorescence levels may also be available - please enquire with your local Cytiva representative for more information.
