Description
BOLA spherical ground joint grip collar seals S 13 are PTFE sealing elements for laboratory ball-and-socket ground joints. Made of polytetrafluoroethylene (PTFE), each seal combines a protruding grip collar with external sealing rings to support high-vacuum-tight closure, with a stated leak rate below 1 × 0,01 mbar × l × s/1. The robust design is intended for continuous laboratory use and follows European standard size S 13, matching common spherical ground joint shells, balls and sockets. Packs contain 3 pieces; the net weight is 0,0008 kg. PTFE provides broad chemical resistance and dimensional stability for distillation, reaction and vacuum apparatus where reliable joint sealing is required. These BOLA seals from manufacturer Bohlender aid secure assembly and easier handling during set-up or dismantling of glassware trains. They suit research and analytical workflows that depend on durable spherical ground joint interfaces without compromising vacuum performance under routine operating conditions.

Questions about BOLA Spherical Ground Joint Sleeves, S 13 PTFE
What is this article?
BOLA Spherical Ground Joint Sleeves, S 13 PTFE is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
