  • Background Information
  • OverviewThe Steriflip filter unit is designed to work with standard 50 mL centrifuge tubes, which eliminates sample transfer. To filter, just attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply the vacuum. When finished, the filtrate collects in the attached 50 mL centrifuge tube.New pore sizes ideal for Cell Isolation applicationsSteriflip Nylon Net filters are now available in 40, 60 and 100 µm pore sizes, making them ideal for stem cell, cardiomyocite, neurological and skeletal tissue applications. The vacuum-assisted, closed system option ensures sample sterility while enabling faster separation of large volumes of cellular material and improved recoveries.The Steriflip® filter unit eliminates messy pouring during sample transfer. Directly attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply vacuum. The filtrate collects in the attached 50 mL centrifuge tube. Steriflip® filters come in different pore sizes that are ideal for cell isolation. These include nylon net filters in 40, 60 and 100 µm pore sizes, which are ideal for stem cell, cardiomyocyte, neurological and skeletal tissue applications. The vacuum-assisted, closed system ensures sample sterility while enabling fast separation of large volumes of cellular material for efficient recoveries.Features & Benefits•Eliminates messy sample transfer via a simple vacuum-assisted, closed system •Isolate cells from cellular debris using any of the various pore-sized nylon net filters •Ideal for sterilizing small batches of culture media •Attaches to any standard 50 mL centrifuge tube, eliminating unnecesary materials, time and risk of spillage ApplicationsSterilization of Aqueous Solutions (up to 50 mL), Sterile Filtration of Small Batches of Culture Media, Sterile Filtration of Buffers with High Value Protein or Small Molecule Components, Cell Isolation

SCGPS05RE Steritop Threaded Bottle Top Filter 82 
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. Features & Benefits Millipore Express® PLUS membrane for fastest flow rates and low protein binding to minimize absorption and protein loss, which affect downstream performance and costs Durapore® membrane for ultra-low protein binding for minimum absorption and protein loss Snug tight packaging, easy tear-open pouch, and convenient label designs make storing, opening and tracking your devices easy and efficient Stable base and easy grip design of the Stericup® device enable any user to comfortably perform all stages of the workflow in a laminar flow hood Recessed bottom of Stericup receiver flasks allows flasks to be stacked easily in refrigerated spaces Applications Sterilization of Aqueous Solutions (150 mL to 1 L); Sterile Filtration of Culture Media and Buffers with High-Value Protein or Small Molecule Component

  • Background Information
  • Strat-M® Membrane for Transdermal Diffusion TestingExperience the unmatched predictability of Strat-M membrane – a synthetic, non-animal based model for transdermal diffusion testing that is predictive of diffusion in human skin without lot-to-lot variability, safety and storage limitations.Strat-M membrane is designed for screening of:•Active pharmaceutical ingredients (API) •Cosmetic actives •Formulations •Personal care products •Pesticides and chemicals Human Skin CorrelationStrat-M membrane is predictive of diffusion in human skin for a wide range of compounds and formulations. Use the Compound Correlation Tool to learn how well Strat-M membrane will work for you.Reproducible Diffusion Data:No need to repeat testing each time a new lot of skin arrives in the lab. Strat-M membrane is a highly consistent, engineered material that allows you to compare today’s diffusion data with data you will generate next week, or next month. Furthermore, lot-to-lot consistency brings a new level of clarity to your test data, simplifying your analysis.Sensitive to EnhancersStrat-M membrane exhibits differential permeability in the presence of enhancers and is compatible with common formulation formats, so it is appropriate for use during formulation optimization.Ultimate Experimental ConvenienceStrat-M membrane was designed with convenience in mind. The Strat-M membrane is shelf-stable and stocked in the warehouse so procurement and storage is a breeze. Each membrane is individually packaged as precut discs and do not need to be hydrated prior to use. Simply remove the Strat-M membrane disc from its pouch and load into a Franz cell.
