Description
Vacuum stopper, DURAN®, bent 105° with sleeve/core 14/23 is a precision ground-glass joint component for laboratory vacuum work on distillation and extraction apparatus. The stopper integrates a bent geometry of 105° with a standard 14/23 ground joint interface, allowing secure connection to matching conical joints while supporting controlled vacuum pathways in glass assemblies. Manufactured from DURAN® glass, it suits routine set-ups where reliable sealing at the joint and directional tubing orientation are required. This version is supplied as a single piece with a net weight of 0,030 kg and is intended for use among components with ground glass joints in distillation and extraction lines. The compact form factor from manufacturer Lenz fits standard NS 14/23 ports on flasks, adapters and receivers without additional conversion pieces. In the laboratory it supports vacuum-assisted operations, inert-gas handling sequences and closed-system work where a bent vacuum stopper improves hose routing and reduces strain on the joint. Clear joint sizing and the defined bend angle simplify selection when building or maintaining multi-neck glassware trains. Pack size is one unit, ready for immediate incorporation into existing DURAN®-compatible ground-joint systems.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Vacuum stopper, DURAN®, bent 105°, sleeve/core 14/23, 1 unit(s)
What is this article?
Vacuum stopper, DURAN®, bent 105°, sleeve/core 14/23, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
