Product Overview
Hydrophilic asymmetric polyethersulfone membrane ensures excellent flow rates, broad chemical compatibility, low protein binding, low extractability, high mechanical strength, and temperature resistance in a variety of applications for the biopharmaceutical, microelectronics, chemical, food and beverage industries.
These cartridges meet USP Biological Reactivity Test, in vivo for class VI-121°C plastics. Sterilizable using industry recognized and accepted methods.
The Pur-MAXX E now offers a Special Pleat option, which provides expected surface area improvements of as much as 25%. This optimized pleat geometry option was developed for the filtration of process fluids that require a high degree of particle retention and/or constant bacterial barrier for effective sterilization.
Features & Benefits
High surface area membrane offers excellent life and flux rates, while providing absolute-rated filtration
Absolute-rated membrane provides reliable, consistent and repeatable filtrate quality
Low pressure drops yield higher flow rates and reduced processing time
Integrity tested
Thermally bonded construction without the use of adhesives or binders, resulting in lower extractables
High strength design allowing for extended use and multi-autoclave cycles
All materials of construction are FDA compliant with CFR Title 21, pharmaceutical grades are bio-safe in accordance with USP Class VI
Non fiber-shedding polyester and polypropylene support materials eliminate fiber migration
Pleat design for greater surface area, ensuring longer service life, fewer change outs and reduced operating costs per element
Pharmaceutical grade elements are 100% integrity tested
Special Pleat Option: Optimized pleat geometry
Special Pleat Option: Expected surface area improvements of as much as 25%
