• TLC Silica gel 60 F₂₅₄ pkg of 25 sheets, sheet L × W 20 cm × 20 cm, plastic support


    General description

    Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pencil on the surface without risk to damage the layer.
    25 Plastic sheets 20 x 20 cm


    Replaces: 5735-7; 5735

    General description

    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
