Silicone stoppers Silicosen ⊃ and Bio-Silico ⊃
Silicosen ⊃ and Bio-Silico ⊃ are specially processed culture plugs in silicone 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.
3 Silicone stoppers Silicosen ⊃ S-Type
Possesses superb permeability and suitable for aerobic bacterium cultures and shaking
cultures.
