Description

General description

Membrane filtration before separation via liquid chromatography removes contaminating particles from solvents and mobile phases, increasing column life, preventing system failure, and ensuring pure samples for downstream mass spectrometric analysis.

Application

Durapore^® PVDF membranes are utilized in a variety of biomedical research applications.

Packaging

100 filters

Features and Benefits

• provides high flow rates and throughput, low extractables, and broad chemical compatibility
• solvent and heat resistant
• exhibits very low protein binding to minimize interaction with the sample and maximize recovery
• varied pores sizes to suit different application needs

Other Notes

Directions for Use

• Organism Retention: Microorganism
• Mode of Action: Filtration (size exclusion)
• Application: General laboratory filtration
• Intended Use: Retention or removal of biological contaminants
• Instructions for Use: Sterilizing filtration of a liquid through a membrane with a 0.2 μm (or smaller) pore size effectively removes biological contaminants, including bacteria, mold and yeast. For the selective retention of larger biological contaminents, liquid filtration through membranes with 0.45 μm (or larger) pore sizes may be used to trap and support microorganism growth for subsequent culture and analysis
• Storage Statement: Store in dry location
• Disposal Statement: Dispose of in accordance with applicable federal, state and local regulations.
