Description
SILICOSEN® sterile stoppers, pink, type L12, are specially processed laboratory stoppers that incorporate regular pores for culture-media preparation and sterilisation. Even pore distribution and good air permeability make them highly suitable for cultivating aerobic microorganisms in microbiological and cell-culture settings. Chemically and temperature resistant, liquid-repellent and reusable, the stoppers are built for repeated laboratory use while maintaining functional performance. Available in packs of 10 pieces from manufacturer Hirschmann, the compact pink L12 format serves culture vessels that need a sterile-style closure with controlled gas exchange. The design pairs liquid-repellent behaviour with the aeration aerobic cultures require, supporting media preparation, sterilisation steps and day-to-day culture maintenance. SILICOSEN® L12 stoppers give laboratories a practical, multi-use sterile closure option when defined porosity and reliable air permeability are essential for aerobic work.

Questions about SILICOSEN® (1 PACK = 10 PCS), STERIL STOPPER, PINK, L12
What is this article?
SILICOSEN® (1 PACK = 10 PCS), STERIL STOPPER, PINK, L12 is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
