Description
Screw cap for 10-30 ml narrow-neck bottle, LDPE natural provides a reliable sealing solution for small-volume laboratory bottles used in sample storage and reagent handling. Manufactured from low-density polyethylene (LDPE) in a natural colour, this lightweight closure ensures a secure fit on compatible narrow-neck bottles in the 10-30 ml range. With a gross weight of only 0,001 kg, it adds negligible bulk while maintaining flexibility and chemical resistance typical of LDPE laboratory plasticware. The screw design allows quick opening and closing, supporting efficient workflows in analytical, research, and quality-control settings. This cap helps protect contents from contamination and evaporation during short- or medium-term storage. Available as a single piece from manufacturer Kautex, it complements standard narrow-neck bottle systems commonly found in laboratories. The natural LDPE material offers good resilience for repeated use under normal laboratory conditions. Ideal for applications involving small liquid volumes, the closure contributes to organised sample management and safe handling of reagents or specimens without introducing unnecessary complexity into daily routines.

Questions about Screw closure für 10-30 ml Narrow neck bottle, LDPE natural
What is this article?
Screw closure für 10-30 ml Narrow neck bottle, LDPE natural is the article on this page. Luminix Health distributes Kautex 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.
