Thermo Scientific Nalgene Rapid-Flow Sterile Disposable 1000 mL Filter Units With 90 mm Sfca Membrane, 0.45 Um

Thermo Scientific Nalgene Conduct vacuum filtration and single-use biological work requiring sterile filtration, prefiltration or clarification of aqueous solutions in the lab or field with Thermo Scientific™ Nalgene ™ rapid-flow™ sterile disposable filter units with sfca membrane. Surfactant-free cellulose acetate (sfca) membranes have lower extractables than standard (ca) membranes. Includes: polystyrene cover; graduated upper chamber and storage bottle (except 115 mL size) integral membrane filter; cellulosic-plugged side arm; quick disconnect tubing adapter. Warranty: 90 days.

• upper chamber separates from storage bottle for easy access to filtrate
• upper chamber clearly marked with pore size, membrane type, catalog number, lot number and expiration date (except 115 mL size)
• leakproof† (except 115 mL sizes) screw cap eliminates pH shift in storage bottle to provide longer life for stored media
• padless membrane support minimizes foaming of proteinaceous samples
• non-pyrogenic and non-cytotoxic
• gamma radiation-sterilized and individually bagged for a 5-year sterile shelf life

surfactant-free cellulose acetate membranes (sfca):
• low protein binding, excellent flow rates, little or no loss of specific proteins
• no wetting agents to affect sensitive cell culture lines
• yellow collar for easy identification
• much lower extractables than standard ca membranes

115 mL sizes:
• compact filter units for quick filtration of 50 to 100 mL of fluid
• unitary construction with non-separable upper and lower compartments
• not intended for post-filtration storage of media (use rapid-flow products if media storage is required)
• 115 mL sizes do not have rapid-flow support plate design
