Description
BOLA sleeve with O-ring is a replacement sealing component for laboratory flow-through filtration setups, supplied as a pack of three pieces. The sleeve is manufactured from PTFE and is combined with an FKM O-ring, giving chemical resistance suited to typical solvent and aqueous filtration work. The membrane diameter is 90 mm and the thread is GL 25, matching the connection geometry of the corresponding BOLA filtration hardware. These sleeves are intended for BOLA flow filtration devices of the N 1670 series, specifically N 1670-24 as listed by the manufacturer. Compact packing and a low net weight of 0,02 kg make the set practical for stock holding beside filtration benches. PTFE provides a non-stick, chemically inert contact surface, while the FKM O-ring supports reliable sealing under normal laboratory operating conditions. The component is offered by manufacturer Bohlender under the BOLA line and supports routine maintenance or change-over of flow filtration assemblies without altering the original GL 25 interface. Suitable for laboratories that standardise on BOLA filtration equipment and need matched spare sleeves in small multi-packs.

Questions about BOLA Gasket with O-Ring, Ø 90 mm, GL 25 Gasket made of PTFE, O-Ring made of FKM
What is this article?
BOLA Gasket with O-Ring, Ø 90 mm, GL 25 Gasket made of PTFE, O-Ring made of FKM 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.
