Description
neoChoice Stirring Closure Kombi-Vac, NS 29, KPG 10 is a laboratory stirring closure engineered for reliable agitation under vacuum. Designed for ground-joint setups with NS 29 and KPG 10 dimensions, it supports continuous stirring while maintaining vacuum integrity in reaction vessels and related glassware. According to GGM testing, operation at 1000 min⁻¹ over 4 hours results in only a 4 mbar pressure increase, underscoring effective sealing performance during demanding vacuum work. Direct drive transmission avoids power loss between motor and stirrer shaft, while centered running at high speeds reduces vibration and wear on bearings and seals. These design choices contribute to stable process conditions and a long service life in routine laboratory use. Supplied as a single piece from manufacturer neolab - Labor, the Kombi-Vac closure suits organic synthesis, process development, and other applications where vacuum-compatible stirring through a standard ground joint is required. It integrates into existing KPG stirring assemblies and helps maintain consistent mixing without compromising the vacuum environment.

Questions about neoChoice Stirring Closure Kombi-Vac, NS 29, KPG 10
What is this article?
neoChoice Stirring Closure Kombi-Vac, NS 29, KPG 10 is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
