White. For the filtration of air and gases, as well as the filtration of solvents and acids.

• Good chemical resistance
• Autoclavable
• Non-sterile

The very low adsorption membranes are hydrophilic, solvent-resistant (pH 3-12) and therefore suitable for the particle removal from solvents.

White. They are recommended for the filtration of aqueous solutions and proteins. Due to their low content of extractable substances, they are suitable for sample preparation in environmental analysis.

• High flow rates
• Low non-specific protein adsorption
• High resistance

White membrane with black grid, for detection of bacteria with dyed media, particle count & microscopy, individually, sterile packaged / non sterile.

Gray membrane (after wetting, black) with white grid, for detection of yeasts and molds, particle count and microscopy, individually, sterile packaged / non sterile.

White. Very low content of extractable materials. Weight constant after 60 minutes of drying at 105 °C. Suitable for residue analysis, microscopic viewing in incident or transmitted light, chemotaxis, x-ray fluorescence, spectrometry and gravimetric analysis. Autoclavable at 121 °C. Other pore sizes and formats are available on request.

Green membrane with dark-green grid, providing optimal contrast to light-colored or transparent bacteria colonies, individually, sterile packaged / non sterile.

Type 111. Resistant to steam sterilisation up to 134 °C, or in dry heat up to 180 °C. Very low adsorption (important when filtering proteinaceous solutions). Suitable for particle removal and ultracleaning of aqueous solutions, methanol, ethanol, high-grade alcohols and residue analysis of fuels and oils. The extractable content of these filters make up <1% of their weight. Other pore sizes and formats available on request.

Type 230. Polycarbonate (PC), white, non-sterile. Ultrapure, polycarbonate membrane with especially smooth surface and fine pore distribution. Applications include COD/TOC testing, particle analysis or epifluorescence microscopy.

White membrane with green grid, for detection of bacteria with dyed media, particle count and microscopy, individually, sterile packaged / non sterile.

Type 250. Polyamide, white. For filtration of alkaline solutions and organic solvents.

Housing made of polypropylene (PP), membrane made of regenerated cellulose (RC). Effective filtration diameter 9.7 mm.

The membrane filters suitable for use in the Microsart™ e.motion are individually sterile-sealed,without protective paper on top of each filter, in a specially designed individual package on a band. For complete traceability, the membrane filter type, diameter, lot number and a unique serial number are printed on the package of each membrane filter unit. Specially developed pore structures of the 0.45 ìm high Flow membrane filters permit faster filtration based on their high flow rates and throughputs.

All Microsart membrane filters are "multi-fit" and can be used in all standard dispenser systems.

The membrane filters have a diameter of 47 mm or 50 mm, and are white, green or grey with a high-contrast 3.1 mm grid.

White. Very low content of extractable materials. Weight constant after 60 minutes of drying at 105 °C. Suitable for residue analysis, microscopic viewing in incident or transmitted light, chemotaxis, x-ray fluorescence, spectrometry and gravimetric analysis. Autoclavable at 121 °C. Other pore sizes and formats are available on request.

Circular filter for ultrafiltration for sample concentration in stirring cells. The PES diaphragm offers a high flow rate.

White, individually sterile packed. Resistant to steam sterilisation up to 134 °C, or in dry heat up to 180 °C. Very low adsorption (important when filtering proteinaceous solutions).
