Description
BOLA ground joint adapter NS 45/40 – NS 29/32 is a PTFE laboratory adapter with standard ground joints for connecting glassware of different nominal sizes. The component is made of polytetrafluoroethylene (PTFE) and combines a NS 45/40 cone with a NS 29/32 socket, allowing a reliable transition between larger and smaller joint systems used in synthesis, distillation and general apparatus setups. Sealing rings on the outside support a tight fit against the mating glass joint, while a knurled grip of 55 mm diameter gives a secure hold for assembly and disassembly without tools. PTFE provides broad chemical resistance to acids, bases and organic solvents, which suits corrosive or high-purity work where metal or elastomer parts are less appropriate. Supplied as one piece with a net weight of 0,125 kg, the adapter from manufacturer Bohlender is intended for everyday laboratory use with modular ground-joint glassware. Its compact design supports reduction or expansion steps in reaction trains, condensers and receivers while remaining easy to clean and handle under typical bench conditions.

Questions about BOLA Ground Joint Adapters, NS 45/40 - NS 29/32 PTFE, with standard ground joint
What is this article?
BOLA Ground Joint Adapters, NS 45/40 - NS 29/32 PTFE, with standard ground joint 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.
