Membrane Filters

Supplier: Sartorius

Cellulose acetate hydrophilic membrane filters. Ideal for biological and clinical analysis, sterility tests and scintillation measurements. Very low protein binding capacity, suitable for aqueous, alcoholic media and hot gases.

Supplier: Sartorius

Cellulose nitrate hydrophilic, gridded membrane filters for colony counting, particle testing and microscopy, with outstanding recovery rates for microorganisms.

Supplier: Sartorius

PTFE hydrophobic membrane filters. For filtration of air, gases, solvents and acids. Sterilisation by autoclaving or ethylene oxide.

Supplier: Sartorius

Hydrophilic polyamide (nylon) membrane filters. For the filtration of alkaline solutions and organic solvents.

Supplier: RANKEM

These nylon membranes are used for filtration of alkaline solutions and organic solvents. Designed for particle removing filtration of water, aqueous solutions and solvents for analytical determination and filtration of mobile phase solvents for HPLC analysis.

Supplier: RANKEM

Cellulose nitrate has the advantage of providing uniform pore structure over the wide range of pore sizes. The high non-specific adsorption of this membrane type makes it indispensible for many blotting procedures and diagnostic kits. Cellulose nitrate assures effective retention with high flow rate. The printed grid eases the counting of bacterial colonies, micro colonies and more.

Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES).

Supplier: MILLIPORE

Cellulose support pads are used to reinforce filters in monitors for contamination analysis. When saturated with growth medium, they can also be used for culturing microorganisms on membranes.

Supplier: MILLIPORE

Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES).

Supplier: MILLIPORE

These PTFE white hydrophilic membrane compatible with all commonly used HPLC solvents. The membrane undergoes a special treatment process to remove any residual extractables, to provide clearer analysis results. They are widely used for HPLC mobile phase filtration, clarifying acids, bases and dilute protein solutions and isolation of RNA.

Supplier: MILLIPORE

These PES white membrane filters provides ultrafast filtration of tissue culture media, additives, buffers and other aqueous solutions. This high throughput, low protein-binding membrane is also used in many of our ready-to-use sterile filtration devices.

Supplier: MILLIPORE

Hydrophobic edge membranes are standard MF-type filters with edges rendered hydrophobic to 3 or 6 mm widths. In antibiotic and bacteriostatic drug sterility testing by membrane filter method, the 6 mm wide non-wetting edge prevents drug intrusion under holder sealing rim.

Supplier: MILLIPORE

These PC hydrophilic membrane are track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. They are composed of polycarbonate film, which has a smooth, glass like surface for clearer sample observation.

Supplier: MILLIPORE

Biologically inert mixtures of cellulose acetate and cellulose nitrate have made MF-Millipore™ membrane filters one of the most widely used membranes in analytical and research applications.

Supplier: MILLIPORE

ZHE (Zero Head Space Extractor) hazardous waste filtration system, which is approved by the US Environmental Protection Agency (EPA) as an apparatus for Toxicity Characteristic Leaching Procedure (TCLP) measurement. The system cannot pressurise unless completely assembled; this eliminates accidentally 'shooting the piston' out of the unit and assures safe operation. Choose both manual and automatic venting modes.

Supplier: MILLIPORE

PVC membrane filters are specified by ASTM, NIOSH, and OSHA in air monitoring applications to analyse silica, carbon black, metals, quartz particulates and others.
