SteriBell 50^TM Filter

Description

MS SteriBell 50^TM PES devices offer a convenient and efficient way to sterile filter small volumes using a peristaltic pump, syringe filter or other pressurized source. It is ideal for aqueous solutions, especially where low protein binding is required. Because of its broad pH range compatibility, it is suitable for many acids and bases. Also suitable for scale-up studies. Available with glass fiber prefilter.

SteriBell 50-PES-50mm Pressure Driven Filter Device

Features & Benefits

Superior flow rates compared to most competitive products - offers reduced filtration times.
Optional glass fiber prefilter layer offers superior throughput for difficult to filter solutions, buffers, media and serums - fewer changeouts and fewer devices required.
Sterile Filtration - eliminates the need for post-filtration sterilization.
Integrity testable - to ensure sterility.
Can be used as an inline or POU filter - offers convenient use.
Available with detachable filling bell - helps prevent splashing and contamination.
Tapered hose barb accepts different tubing sizes - offers connection flexibility.
Pre-sterilized by gamma irradiation - eliminates contamination associated with EtO.
Sterile packaged - eliminates pre-sterilization.
Disposable - offers convenience versus replacing discs in discs holders.
pH range: 1-12
