Description
BOLA grip collar sleeves, NS 10/19 PTFE, reusable are laboratory ground-joint sleeves manufactured from polytetrafluoroethylene (PTFE) with a protruding grip collar and sealing rings on the outer surface. They provide high-vacuum-tight sealing with a low leak rate of less than 0,0001 mbar × l/s, supporting demanding joint connections on glass apparatus. The robust construction is intended for continuous laboratory use, while the accessible external sealing rings remain easy to clean between runs. Dimensions correspond to European standard size NS 10/19. Supplied as 1 pc with a net weight of 0,0016 kg, each sleeve fits single-joint replacement or assembly tasks in research and routine workflows. These reusable PTFE sleeves from manufacturer Bohlender combine collar handling convenience with reliable outer-ring sealing for vacuum and general laboratory service. The fluoropolymer material offers the chemical inertness expected at standard taper joints, and the grip collar aids placement and removal without compromising the high-vacuum performance of the sealed interface.

Questions about BOLA Sleeves with Gripping Ring, NS 10/19 PTFE, reusable
What is this article?
BOLA Sleeves with Gripping Ring, NS 10/19 PTFE, reusable is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
