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.
Superb permeability and fits tight onto the media container due to sealing lip, where importance is placed on mounting quality. Suitable for shaking cultures.
