Filter Membrane MCE, 0.22–0.45 µm, Pack of 200

Description

The Filter Membrane MCE, 0.22–0.45 µm, also known as mixed cellulose ester membrane filters, cellulose acetate/nitrate membranes or laboratory microfiltration discs, is designed for separating suspended particles from compatible liquid samples during laboratory filtration procedures. Manufactured from Mixed Cellulose Ester (MCE), a combination of cellulose acetate and cellulose nitrate, these membrane filters feature a naturally hydrophilic structure suitable for filtering aqueous solutions. The membrane provides a porous barrier that retains particles according to the selected pore size and filtration conditions.

The range includes four variations, combining membrane diameters of 13 mm, 25 mm and 47 mm with pore sizes of 0.22 µm and 0.45 µm. These options allow laboratories to select an appropriate membrane according to their filtration apparatus, sample requirements and intended analysis. The 0.22 µm MCE membrane, available in a 13 mm diameter, is suitable for fine filtration applications requiring retention of smaller suspended particles. This pore size may also be used for microbial retention when the membrane and complete filtration process are appropriately validated. The 0.45 µm MCE membranes are available in 13 mm, 25 mm and 47 mm diameters. This pore size is commonly used for routine aqueous sample clarification, particulate removal and microbiological membrane filtration under suitable testing procedures. The different membrane diameters provide flexibility for various laboratory filtration arrangements. The 13 mm filters are suitable for small-format membrane holders, while the 25 mm and 47 mm filters accommodate appropriately sized filtration assemblies.

The hydrophilic MCE membrane material supports filtration of water-based samples without requiring pre-wetting with organic solvents. However, chemical compatibility must be confirmed before use with concentrated reagents or organic solvents that may damage the membrane. These membrane filters are used in water quality testing, environmental monitoring, microbiological analysis and routine laboratory sample preparation. Their fine pore structure allows users to separate particulate material from liquids before further examination or testing. For filtration, position the selected membrane correctly inside a compatible filter holder or membrane filtration assembly. Ensure the membrane is supported, properly sealed and handled carefully to avoid tears or contamination.

Safety Precautions: Use clean forceps when handling membrane discs and avoid touching the active filtration surface. Confirm chemical compatibility, operating pressure and membrane suitability before use. Sterility and microbial retention performance must be verified for procedures requiring sterile filtration. Each selected variation is supplied as one pack of 200 MCE Membrane Filters in the chosen diameter and pore size. Filter holders, vacuum pumps, filtration funnels and other laboratory accessories are not included unless specified separately.

LabChoice Australia supplies mixed cellulose ester membrane filters, laboratory filtration consumables and sample preparation equipment for chemistry laboratories, microbiology facilities, universities, research institutions, environmental testing laboratories and industrial quality control environments.
