For microscopy and visual analysis. Isopore Membrane Filter is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. It offers distinct advantages for analysis

Designed for easy handling and maximum safety in air filtration. Sartorius™ Midisart™ 2000 PTFE Air Filter entirely eliminates moisture breakthrough because of its inherently hydrophobic PTFE membrane reinforced with polypropylene gauze. Stepped hose barb connectors ensure a simple and secure hold.

Membrane Filters suitable for use in the Microsart e.motion dispenser

Hydrophobic membrane with laminated backing for easier handling

Recommended when maximum recovery is important

Polyethersulfone (PES) filters have a high internal porosity.

Protect the vacuum source during aspiration with this membrane filter. Integra Biosciences™ Hydrophobic Membrane Filters are designed for use with VACUSAFE Aspiration Systems.

Plain white polyethersulfone membranes provide ultrafast filtration for a variety of applications

Recommended when maximum recovery is important. Durapore™ PVDF Membranes: 0.45μ 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.

Ensure quality control in microbiological filtering. Sartorius™ Gridded Sterile Cellulose Nitrate Membrane Filters, 0.45μm are single-packed membranes with colored grids for colony counting, particle testing and microscopy. The 0.45μm pore size is made in accordance with ISO 7704. Choose from two diameters and quantities in a range of filter/grid color combinations.

Reduces background fluorescence in support of epifluorescence microscopy. Whatman™ Nuclepore™ Black Polycarbonate Membrane Filters improve visibility and help to distinguish microorganisms from other particulates.

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

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