Description
BOLA guide tube for magnetic stirrer couplings is fabricated from borosilicate glass with a ground joint core and a bonded upper bearing, offering KPG guidance at an inner diameter of 19. It features a larger standard ground joint NS 45/40 together with a left-hand thread M21x for coupling attachment. Delivered as one piece and weighing 0,173 kg net, the component establishes a defined bearing path for magnetic stirrer couplings on laboratory reactors and comparable glass systems. An alternative version without ground joint is available for fusion onto a reactor lid, with the upper bearing supplied for user bonding. From manufacturer Bohlender, the BOLA guide tube unites borosilicate chemical resistance with accurate KPG sleeve geometry. The NS 45/40 joint provides a robust, standardized connection to matching glassware, while the left-hand thread ensures correct orientation of the magnetic coupling. This sleeve is intended for applications that demand a KPG guide tube with NS 45/40 interface and reliable upper bearing support in stirred reactor setups.

What is this article?
BOLA Conductors for Magnetic Stirrer Heads, IØ 19 KPG, NS 45/40 Left-handed thre 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.
