SILICOSEN^® and BIO-SILICO^® are specially processed culture plugs in sterile rubber with continuous bubbles for preparation, filling and sterilisation of culture media. Their uniform pore structure and good air permeability make them excellent for the cultivation of aerobic microorganisms.

The choice between SILICOSEN^® and BIO-SILICO^® culture stoppers depends on the requirements of the application. SILICOSEN^® culture stoppers have low water evaporation which makes them particularly suitable for long term cultures. BIO-SILICO^® culture stoppers have high air permeability, similar to cotton plugs. Both types are chemically resistant, temperature resistant, liquid repellent and reusable.
Cell size is uniform, which provides stable and good permeability. Optimum product for shaking cultures-durability and operability are excellent.
