Description
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
