SILICOSEN® sterile stopper are specially processed culture plugs in steril stopper with continuous bubbles for preparation, filling and sterilisation of culture media. Their uniform pore structure and good air permeability make them excellent for the cultivaton of aerobic microorganisms. Both types are chemically resistant, temperature resistant, liquid repellent and reusable. SILICOSEN® culture stoppers have low water evaporation which makes them particularly suitable for long term cultures. Moisture evaporation is minimal, thus there is less drying of the culture medium. Colour: natural.
