Filtration Membrane Discs

Thin, precut membrane rounds for high-throughput, fast filtration of liquid and gas samples. Gridded and non-gridded discs. Various materials including mixed cellulose ester, polycarbonate, PTFE, nylon, and PVDF. For air monitoring/analytical research.

Sizes

Filter membranes are made in a range of diameters, typically designed to fit a specific holder or manifold.

Materials

Filter membrane can be made from cellulose, mixed cellulose esters (MCE), polyvinylidene fluoride (PVDF), polyethersulfone (PES), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), nylon, polycarbonate (PC), polyester, polyethylene terephthalate (PET), and polypropylene (PP). Other membrane materials include aluminum oxide, gelatin, porcelain, and glass.

Pore Size

The size of membrane pores determines which particles will be retained by the filter. A pore size of 0.2 µm is small enough to remove microbes from solutions; a 0.45 µm ore size can remove larger particulates.

Color and Grids

White membrane filters may be plain or marked with square grids (outlined in black) that can help with enumerating particles. Gridded or plain black membrane filters may be helpful when filtering light-colored particulates.

Sterility

Filter membranes may be pre-sterilized or may be sterilized using ethylene oxide, gamma irradiation, or autoclaves. The need for sterility is determined by the application, which are many and varied:

Light microscopy samples
Cytology sample preparation
Electron microscopy samples
Air quality and other environmental monitoring
Water analysis and water quality testing
Microbiology colony counting and quality control
Chemotaxis
Sterile preparation of buffers, tissue culture media, microbiological media, and other biological fluids

Cole-Parmer Stuart WOLFFHUEGAL DISCS 10/PK

Features a robust die-cast body to prevent traveling while on, and has an integrated port to support a lab rod for holding vessels in place during continuous operation. The variable-speed allows more control—use at 200 rpm for more gentle mixing, all the way up to 2500 rpm for vigorous agitation. Additionally, choose between "touch" on or continuous modes. The accessory pack of heads (sold separately) lets you mix in a standard microplate, a beaker or flask (up to 500 mL), eight 0.2-/0.5-mL microtubes, sixteen-1.5 mL microcentrifuge tubes, or make your own custom holder with the blank foam.
