The Nonsterile Membrane Filters are made of cellulose nitrate (cellulose mixed ester), cellulose acetate or regenerated cellulose. They can be used for colony counting, particle testing and microscopy. Choose between gridded or non-gridded, membranes, either with or without hydrophobic edge.

Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.

Naturally hydrophilic membrane designed to wet out evenly and retain its superior strength during use in general filtration or medical assays.

Flexible and durable for easier handling.   Cytiva Nylon Membranes are naturally hydrophilic, eliminating need for wetting agents and prewetting when filtering aqueous solutions.

Ensure quality control in routine microbiological filtering. Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.2μm are single-packed membranes with black grids for colony counting, particle testing and microscopy. The 0.2μm pore size is BCT validated. Choose from two diameters and packaging quantities.

Prepares liquid scintillation cocktail for scintillation counter measurements. Whatman™ Cellulose Acetate Membranes are highly heat resistant and can filter hot liquids and hot gases.

Two CultureGard™ filters used in series provide the ultimate sterile barrier against the risk of culture contamination possible during media feeding and culture perfusion

Used with seripettor™ / QuikSip™ / accu-jet™ pro macro pipet controllers. Filter Membranes are available in 3μL capacity and provided in blister pack packaging.

Hydrophilic nylon membrane

Filters for colony counting, particle testing and microscopy.

Recommended when maximum recovery is important

Mixed cellulose esters (MCE) membrane, hydrophilic

Membrane filters suitable for use in the Microsart @Filter units

Recommended for majority of routine applications, this membrane is manufactured under strictly controlled conditions.  Whatman™ Type WCN Cellulose Nitrate Membranes narrow pore size distribution for improved surface capture and analysis.

General purpose membrane that provides excellent performance with most solutions when retentate recovery is of primary importance.

Provides clarification of corrosives, solvents, and aggressive fluids. Whatman™ PTFE Membrane Circles are particularly useful in HPLC analysis when solid particles can cause permanent damage to the column.

Recommended when maximum recovery is important. Durapore™ PVDF Membranes: 0.22μ Pore Size provide high flow rates and throughput, low extractables, broad chemical compatibility and low protein binding. Available in diameters ranging from 13mm to 142mm.

Membrane filters suitable for use in the Microsart @Filter units

Combines high flow rates and thermal stability with very low adsorption characteristics. Sartorius Cellulose Acetate Membrane Filters are excellently suited for use in pressure filtration devices. Non-sterile filters in a variety of diameters and pore sizes are bulk-packed to save money and space.

Constructed with precision pore structure and narrow pore size distribution. Whatman™ Anodisc™ Filter Membranes ensure a high level of particle removal efficiency. Captures microorganisms and particulates on the surface of the membrane for subsequent analysis.

Whatman™ (ME 27) Mixed Cellulose Ester Membranes, Plain are particularly effective in applications requiring higher flow rates and larger volume filtration including clarification or sterilization of aqueous solutions, particulate analysis and removal, air monitoring, and microbial analysis.

Fisherbrand™ Mixed Celluloses Esters Membranes Sterile Filters are composed of cellulose acetate and cellulose nitrate.

Fisherbrand™ Mixed Celluloses Esters Membranes Non-sterile Filters are composed of cellulose acetate and cellulose nitrate.

Fisherbrand™ Polyethersulfone Membranes features highly asymmetrical pore structure that offers effective loading capacity and high flow rate.

Carry out particulate and microbial analysis with these filter membranes. Available in various forms for water quality work, cold sterilization or sample clean up.

Fisherbrand™ PTFE membrane is hydrophobic filter made of polytetra-fluorethylene laminated with PP layer.

Ideal for filtering or sterilizing nonprotein-containing biological solutions.

Suitable for Clarification and sterilizing filtration of biological fluids . Fisherbrand™ Cellulose Membranes filters are composed of pure cellulose acetate modified to offer researchers the lowest binding filters available.
