Description
neoChoice screw caps without hole with butyl/PTFE seal are precision closures designed for autosampler vials of 1,2 ml capacity featuring an 8-425 thread.

Supplied in convenient packs of 100 pieces, these caps support high-throughput sample preparation in HPLC, GC and related analytical workflows. The butyl layer ensures elasticity and resealability while the PTFE face offers inert contact with the sample. Suitable for routine laboratory use where consistent sealing performance and solvent compatibility are required. These neoChoice screw caps from manufacturer neolab - Labor deliver dependable closure for threaded micro-vials without the need for a centre hole, simplifying handling and reducing contamination risk in autosampler applications.

Questions about neoChoice screw caps without hole with Butyl/PTFE seal, 100 pcs./pack
What is this article?
neoChoice screw caps without hole with Butyl/PTFE seal, 100 pcs./pack is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
