Description
The check valve NS 14/23 according to Friedrichs-Antlinger is a laboratory glassware component fitted with an exchangeable plastic valve cone. This non-return valve prevents reverse flow in apparatus that require controlled unidirectional passage of gases or liquids. The NS 14/23 ground joint guarantees compatibility with standard laboratory glass systems used in distillation, reaction and vacuum setups. Produced by manufacturer Witeg, the design permits simple replacement of the plastic cone, supporting straightforward maintenance and extended service life. With a net weight of only 0,024 kg it remains a lightweight yet essential accessory for research and analytical laboratories. The Friedrichs-Antlinger configuration is valued for dependable sealing performance within scientific glass assemblies. It integrates readily into complex apparatus where protection against backflow is critical, helping maintain process integrity and operator safety during routine experimental work.
