SCGPS01RE Steritop Threaded Bottle Top Filter 67 
Add to Cart
  • Background Information
  • The Stericup® vacuum filtration system is the most efficient single-use, disposable process for sterile media preparation. It combines a Steritop® filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL in a single, ready-to-use format. Its no-tip, easy-grip flask design and balanced profile improve stability during filtration in tight laminar flow hoods, and the convenient labeling and packaging make it easy to open and track each device. The bottom of the receiver flask is slightly recessed, so you can conveniently stack capped flasks after filtration, maximizing precious refrigeration space. You can also use Steritop® bottle-top devices with your own sterile capture flask or bottle.

Add to Cart
  • Background Information
  • The Stericap™ PLUS Universal Bottle-Top Filter Device with Millipore Express® PLUS membrane provides fast vacuum filtration and low protein binding without the need for a prefilter in most cases. It filters quickly, without clogging, even viscous solutions typical of serum-containing media. This non-cytotoxic, non-pyrogenic device can be used to fill any vacuum-rated bottle or other container with an inner neck diameter of 20 to 67 mm. This allows maximum versatility, capacity, speed, and flowthrough efficiency when you need to filter larger volumes into containers with openings of various sizes.Features & Benefits: - Millipore Express® PLUS membrane for fastest flow rates and low protein binding - Fits any vacuum-rated bottle from 20 to 67 mm in diameter for maximum flexibility - High volume capacity for larger and less frequent preparation steps - Easy flow control button so the filter can be easily transferred from bottle to bottle without turning off the vacuum each time - Free of cytotoxic and pyrogenic contaminants for robust cell culture and sensitive downstream applications Applications:Sterilization of Aqueous Solutions, Media Preparation, Buffer Preparation
