Beschrijving
Chain clamp, plastic, DN 40 is a laboratory accessory for securing compatible connections on vacuum and process lines with nominal diameter DN 40. Fabricated from plastic, the clamp delivers a lightweight fastening solution for assembling and maintaining laboratory apparatus that uses DN 40 interfaces. It is supplied as one piece, so it can be stocked cleanly as a dedicated spare for pumps, larger transfer lines, filtration units and related equipment. In everyday laboratory use, chain clamps in this size help keep joints accessible for inspection, cleaning or component exchange while supporting orderly connection management. The DN 40 format corresponds to a common larger vacuum fitting size found in many research and analytical setups. This accessory from manufacturer WELCH forms part of the range of accessories and spare parts for laboratory equipment and pairs naturally with smaller DN plastic chain clamps when laboratories standardise fastening hardware across multiple line sizes. Its plastic construction is suited to routine handling where a non-metallic clamp is specified for process and vacuum connection work.
This article is part of Clamps & bossheads, in Stands, clamps & racks.

Questions about Chain Clamp, Plastic, DN 40
What is this article?
Chain Clamp, Plastic, DN 40 is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labmateriaal.
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.
