Description
BOLA vacuum adapter with ground joint NS 19/26 is a PTFE laboratory connector for vacuum filtration assemblies. The through-passage is fitted with an FKM O-ring that allows standard glass or plastic filter funnels to seat securely on vessels and round-bottom flasks carrying a matching ground joint. A lateral stepped olive, also manufactured from PTFE, provides the vacuum-pump connection via suitable tubing and offers outer diameters of 9 mm and 12 mm. The cone is specified as NS 19/26 and accepts funnel outlets up to a maximum diameter of 11 mm. Supplied as one piece with a net weight of 0,039 kg, the adapter from manufacturer Bohlender is intended for routine filtration work where chemical resistance and a reliable vacuum seal are required. PTFE construction supports use with many common laboratory media, while the stepped olive simplifies hose attachment without additional adapters. This compact ground-joint vacuum adapter integrates cleanly into existing glassware setups and helps maintain stable vacuum conditions during solid–liquid separations in research and quality-control laboratories.

Questions about BOLA Vacuum Adaptor with Ground Joint, NS 19/26 Cone NS 19/26 lateral 2-step hos
What is this article?
BOLA Vacuum Adaptor with Ground Joint, NS 19/26 Cone NS 19/26 lateral 2-step hos is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
