Description
Nalgene™ spigot closure with lock nut is a polypropylene and thermoplastic elastomer (TPE) container spigot accessory designed for secure dispensing from laboratory vessels. The polypropylene lock nut and TPE stopper fit all 1-1/8 in. spigot necks and accept tubing with a 16 mm inner diameter, supporting reliable liquid transfer in routine lab workflows. It is intended for use with Nalgene carboys, transparent carboys, flat canisters and tanks that share the matching 1-1/8 in. thread size, helping maintain a tight seal during storage and dispensing. Supplied as a case of 24 (packs of 4) from manufacturer Thermo Scientific - Laboratory Plastics, this accessory suits bulk fluid handling, media preparation and general laboratory liquid management where a replaceable spigot closure is required. The combination of rigid PP hardware and flexible TPE stopper supports repeated opening and closing while matching the original Nalgene vessel interface. Ideal for laboratories standardising on Nalgene plasticware systems that need compatible spigot closures without altering existing bottle or tank threads.

Questions about Nalgene™ Polypropylene, Spigot Closure with Polypropylene Lock Nut and
What is this article?
Nalgene™ Polypropylene, Spigot Closure with Polypropylene Lock Nut and is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
