Description
Chain clamp, plastic, DN 25 is a laboratory accessory intended for fastening compatible connections on vacuum and process lines with nominal diameter DN 25. Constructed from plastic, it provides a practical, lightweight clamp for securing matching flanges or interfaces during setup, operation and service of laboratory equipment. Supplied as a single piece, the item is easy to hold in spare-parts inventories for pumps, transfer lines, filtration assemblies and other apparatus that rely on DN 25 fittings. In laboratory workflows, chain clamps of this size support quick opening and closing of joints when components must be exchanged or cleaned. The DN 25 designation matches a widely used mid-range vacuum connection format across analytical and research installations. Offered by manufacturer WELCH, the clamp belongs to the category of accessories and spare parts for laboratory equipment and complements smaller and larger DN plastic chain clamps for standardised workstation stocking. Its plastic build suits applications where a non-metallic fastening solution is preferred for routine laboratory handling and organisation of process connections.

Questions about Chain Clamp, Plastic, DN 25
What is this article?
Chain Clamp, Plastic, DN 25 is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labware.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
