Mixed cellulose ester membranes, well suited for microbiological analysis of water, wastewater, pharmaceuticals, or beverages. Advantec MFS™ Cellulose Ester Membrane Filters feature a gridded surface for colony counting.

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.

Strengthened glass filter media by dual lamination with a tough polyester monofilament. Whatman™ HEPA-Vent Filters are ideal for air and gas filtration applications where high retention, dirt-holding capacity and flow rates are required.

Ergonomic design allows easy measurement of more than 350 gases—including formaldehyde

Used for sterile filtration of blood and plasma products and vaccines.

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

Filter aggressive chemicals, including acids and non-aqueous solvents such as those used in GC and HPLC with this in-line syringe filter with PTFE membrane.

Supplied in medium or coarse porosity

For use in HVAC and mining industries.

Detector tubes

Immobilon Transfer Membranes offer the convenience of pre-cut sheets with the flexibility of membrane rolls

Fluid Contamination Analysis Monitors are transparent, disposable filter holders made from Tenite™ plastic and pre-assembled with MF-Millipore filters (effective filtration area is 9 cm2).

Accessories for filter holders for sample preparation.

Creates a hydrophobic filter that can replace separatory funnel in some applications. Whatman™ 1PS Disposable Phase Separating Paper is impregnated with stable silicone to allow solvent phases to pass through while retaining aqueous phases.

Unlaminated for extreme chemical or temperature conditions

Used in many air sampling filter applications, including sampling of acidic gases, stacks, flues, and aerosols. Whatman™ Quartz Air Sampling Filters are sequentially numbered according to U.S. Environmental Protection Agency (EPA) standards and are suitable for most applications.

Highly robust digital micrometer with outstanding accuracy. Mitutoyo™ IP54 Digital Micrometer features extraordinary battery life.
