Description
Silicone stopper with upper diameter 24,0 mm, lower diameter 18,0 mm and length 30 mm is a transparent, flexible laboratory closure for sealing vessels, flasks and apparatus in routine and research work. The tapered geometry supports a secure fit across a useful range of neck openings, while the soft silicone body conforms well to glass and other smooth surfaces without excessive force. Flexibility aids insertion and removal and helps maintain a reliable seal during handling, mixing or short-term storage of samples and reagents. Supplied as a practical pack of 10 pieces, the stoppers suit standard laboratory organisation and replacement needs. Manufactured by Witeg, this silicone stopper belongs to the common range of norm, rubber and silicone stoppers used for general laboratory sealing tasks. Net weight is approximately 0,01 kg per unit. Choose this size when a medium taper between 24,0 mm and 18,0 mm and a 30 mm length match your glassware openings and workflow requirements.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Silicone plug O-Ø 24.0mm U-Ø 18.0mm length 30mm
What is this article?
Silicone plug O-Ø 24.0mm U-Ø 18.0mm length 30mm 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.
