Description
ÜK N20-L silver aluminium overpressure safety cap with centre hole is an N 20 closure equipped with a ready-to-use faced butyl/PTFE grey septum disc. Hardness is 50° Shore A and septum thickness is 3,0 mm, matching common specifications for analytical vial sealing where controlled venting behaviour and a defined liner geometry are required. The aluminium shell is finished in silver and designed as an Überdruck-Sicherheitskappe for N 20 neck finishes used in chromatography sample handling. Supplied in packs of 100 pieces, the format supports high-throughput laboratories that need consistent cap and septum combinations. This overpressure safety cap from manufacturer Macherey-Nagel pairs a metal N 20 open-top design with a grey butyl/PTFE faced disc for sample contact and resealing performance typical of GC accessory workflows. The faced septum construction simplifies assembly compared with loose liners and helps standardise sealing across instrument sequences. Select matching N 20 vials and follow laboratory crimping or capping practice for reproducible headspace conditions.

Questions about PR N20-H, si, Mld. But/PTFE gr, 50°, 3.0
What is this article?
PR N20-H, si, Mld. But/PTFE gr, 50°, 3.0 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Solvent waste caps, safety funnels & canisters, inside Waste disposal, in Lab safety equipment.
A solvent waste cap and a safety funnel close a waste can so vapour does not fill the room, while still letting waste be poured in. The thread has to match the can. A filter and a level indicator are common features. An open beaker of waste solvent is not this article.
Laboratory waste is sorted before it is carried away. A solvent waste can has a cap and often a funnel that limits vapour. A sharps container is rigid and closable. An autoclave bag is for material that will be sterilised before it is ordinary waste. The container has to survive the chemical that goes into it. A bag that dissolves is not a container. Classification of the chemicals is on ECHA. Transport of dangerous goods is the UNECE framework. Workplace practice is EU-OSHA.
