Hach. These 47-mm diameter, 0.45-µm pore size GN-Metricel membrane filters meet or surpass all U.S. Environmental Protection Agency (USEPA) and American Society for Testing and Materials (ASTM) specifications to ensure complete retention and maximum recovery of bacteria. Phosphate free.

As with all Geotech filter membranes, they are Triton-free and non-reactive to pyrogens (<0.005ng/cm 2 filter area). PTFE Membrane: Are highly porous and resistant to most acids, bases and chemically aggressive solvents. They are naturally hydrophobic making them difficult to use in common filtration of aqueous solutions.

The membrane will then allow bulk flow of water for as long as the pore remain water filled. If the membrane is allowed to dry (i.e. air enters the pores), then it must be pre-wet with a low surface tension fluid again prior to use with water. Hydrophobic membrane filters are typically used with compatible non-aqueous fluids.

Perfect for HPLC mobile phase filtration, drinking water monitoring and bacteria monitoring. Available in 13, 25 and 47mm diameters. Available in porosity of 0.22um and 0.45um. Membranes available: Nylon, mixed cellulose ester, hydrophilic PVDF and PTFE. Membrane manufacture in north America.

Advantec MFS. Advantec Disposable Petri Dishes are ideal for culturing microorganisms on a 47mm diameter membrane filter. The dishes are made of high-quality polystyrene material and are pre-sterilized by gamma irradiation. The dish features a squared edge and a raised ridge for ease of handling and secure.

The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC. Chemically stable and inert PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents.

47 mm (filter), 7.6 cm (funnel) Filtration Area. 9.6 cm2. Volume (Metric) 300 mL. Includes. 300 mL Funnel, Spring Clamp, Glass Base and Stopper and Alignment Guide. Type. Glass Vacuum Filter Holder.

Inherently hydrophobic, PTFE membranes will not absorb moisture from air or gases, making it ideal for venting applications, phase separations and aerosol samplings. Laminated PTFE filters can be used to filter aqueous solutions when prewetted with methanol. They are autoclavable up to 130°C (260°F).

Fluoropore Membrane Filter 0.45 µm pore size, hydrophobic PTFE, 47 mm membrane - Find MSDS or SDS, a COA, data sheets and more information.

PTFE Laminated Membrane Filters, 0.45 Micron, 47mm, 100/Pk. PTFE Laminated Membrane Filters, 0.45 micron, 47 mm, pack of 100. Hydrophobic, durable ePTFE laminated on to a polypropylene later. Ideal for venting, phase seperations, and aerosol sampling.

Membrane Filters, PTFE, 47mm. Whatman’s range of membrane filters with advanced technical specifications are the preferred choice for a wide range of applications. The membrane filters offer accurately controlled pore size distribution and higher strength and flexibility, which ensure reproducibility and consistency. Tisch Scientific supplies competitively-priced Whatman membrane filters, including PTFE Filters, PVDF Membrane Filters, Nylon Membrane Filters, Cellulose Acetate Membrane

PVDF membrane filter’s biggest feature is very low protein adsorption, and the hydrophobic membrane filter can also be used to filter gas. PVDF filter is commonly used for purification during sterilizing or clarifying procedures. Sterile PVDF filter membrane are often used for biological sterilization filtration after hydrophilic treatment.

47mm filter diameter Available in type 304ss or 316ss Filter liquids or gases at point-of-use This 47mm in-line holder (model KS47) is available in both type 304 or 316 stainless steel. The PTFE coated support screen prevents sticking of the membrane during autoclaving.
