BIO-SILICO® sterile stoppers in orange, size N52, are stoppers produced by a special process with regular pores, ideal for preparing and sterilising culture media. Even pore distribution and good air permeability make them well suited to cultivating aerobic microorganisms. The stoppers are chemically and temperature resistant, liquid-repellent and intended for multiple use in the laboratory. Delivered as a pack of 10 pieces from manufacturer Hirschmann, the orange N52 format supports culture-media work, tube closure and related microbiological handling. Porous construction promotes reliable gas exchange for aerobic cultures, while liquid-repellent behaviour assists clean media preparation and sterilisation steps. Typical use aligns with cover caps, culture caps and test-tube closures where air-permeable, durable stoppers are needed. BIO-SILICO® identifies this specialised sterile-stopper range for consistent pore geometry in culture workflows. Pack net weight is 0,413 kg, with Japan as country of origin.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about BIO-SILICO® (1 PACK = 10 PCS), STERIL STOPPER, ORANGE, N52
What is this article?
BIO-SILICO® (1 PACK = 10 PCS), STERIL STOPPER, ORANGE, N52 is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labmateriaal.
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.
