Description
ST30K behrotest® stopper NS19 is a transparent laboratory stopper made from PPC and intended for Karlsruhe bottles. Measuring 69 mm in length, it is sized for standardised NS19 joints so that sample bottles used in water analysis and environmental testing can be closed securely during storage, transport, or preparation steps. The transparent PPC body allows visual checks at the bottle neck while offering the chemical resistance expected in routine wet-chemistry work. Designed specifically for Karlsruhe-type vessels, the stopper supports consistent sealing geometry across series of samples and helps maintain reliable closures in daily laboratory practice. This single-piece accessory from manufacturer Behr fits into behrotest® bottle setups commonly found in environmental and water-testing laboratories. It is suitable wherever NS19 stoppers are required for Karlsruhe bottles and where a defined length and transparent polymer construction simplify handling and inspection. The ST30K stopper is a practical consumable for analytical workflows that depend on standardised joint sizes and dependable bottle closures.
