General description

Filter Code: HPWP

Filter Type: Screen filter

The Millipore Express PLUS membrane provides ultrafast filtration of tissue culture media, additives, buffers and other aqueous solutions. This high throughput, low protein-binding membrane is also used in many of our ready-to-use sterile filtration devices.

Features & Benefit:
•Ultra fast filtration and high throughput shorten process time
•Can be sterilized by autoclave, ethylene oxide, or gamma irradiation for sterile filtration applications

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.
