Description
Flexible stopper for sample tubes with Ø 13 mm in green is a polyethylene laboratory closure intended for sealing sample tubes during routine laboratory handling. Made from polyethylene, it is flexible and adapts to the tube opening so that it seats cleanly on matching 13 mm tubes. Within the series, stoppers are offered for tubes of 13 mm and 16 mm diameter; this green variant is specified for the 13 mm size and supports clear visual differentiation of samples, batches or process stages. Colour coding in green complements other colours in the same range for organised rack and workflow management. The pack contains 1000 pieces with a net weight of 1,000 kg, making it suitable for continuous use in busy sample-preparation and storage areas. These stoppers from manufacturer Labbox (product type ASTIKS) provide a practical polyethylene option for temporary or intermediate closure of sample tubes. The flexible construction eases insertion and removal while helping limit spillage during internal transport and short-term holding. They fit general laboratory materials needs wherever standardised 13 mm tube stoppers and colour identification are preferred.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Flexible stopper for test tubes, for Ø 13 mm tubes, red
What is this article?
Flexible stopper for test tubes, for Ø 13 mm tubes, red is the article on this page. Luminix Health distributes Labbox 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.
