Description
Push-in stoppers LDPE 15x17 mm are disposable laboratory closures intended for single-use test tubes with an outer diameter of 15–17 mm. Moulded from low-density polyethylene (LDPE) in a neutral colour, the stoppers offer a practical, chemically resistant seal for temporary covering of culture tubes, sample tubes and similar glassware. A ribbed outer profile improves handling and helps the stopper seat firmly in the tube mouth without tools. These push-in stoppers from manufacturer Witeg are well suited to routine sample handling, short-term storage and transport of aqueous or mild laboratory media where a simple, economical LDPE cap is preferred over screw caps or foil. The large pack of 1000 pieces supports high-throughput workflows in clinical, teaching and research laboratories while keeping consumable costs low. Lightweight and ready to use straight from the pack, they provide a reliable everyday solution for covering disposable test tubes in the 15–17 mm range.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Push-in plugs LDPE 15-17mm
What is this article?
Push-in plugs LDPE 15-17mm is the article on this page. Luminix Health distributes Witeg 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.
