Excellent permeability and secure fitting, thanks to seal lip. Ideally suitable for agitated cultures. 

SILICOSEN^® and BIO-SILICO^® are sterile stoppers manufactured in a special process which have regular pores, thus making them ideal for the preparation and sterilisation of culture media. The uniform pores and good permeability to air make the stoppers ideally suitable for cultivation of aerobic microorganisms. Both versions are resistant to chemicals and temperature, repel liquids and can be used several times.
