Description
DURAN® stretchable silicone lid size L in pink provides a versatile covering and sealing solution for laboratory vessels of many shapes and sizes. Measuring 83,7 mm in diameter with a net weight of 0,014 kg, the lid is supplied as a single piece and forms a practical alternative to glass plates or aluminium foil. Thanks to its elastic silicone material, the cover stretches to fit a wide variety of round or square openings securely. A slightly larger tab acts both as a writing field for sample identification and as a grip that allows easy removal with or without gloves. The pink colour supports clear visual coding alongside the cyan and green variants in the range. Chemically resistant, heat-resistant and reusable, this lid from manufacturer Duran/DWK Life Sciences helps reduce waste while maintaining reliable vessel protection during routine laboratory work. Typical applications include temporary covering of glassware, colour-coded organisation and straightforward sample identification in research, quality control and educational laboratories.

Questions about DURAN® Silicone lid, stretchable
What is this article?
DURAN® Silicone lid, stretchable is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
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.
