Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility.

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: Merck

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: Merck

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.
