Description
Plug-in tunnel, straight, is a stainless steel accessory for guided filling of safety containers and related laboratory vessels. With a diameter of 120 mm and a height of 120 mm, the straight tunnel helps direct liquid into the receiving container during transfer operations, supporting cleaner and more controlled filling. The unit is supplied as 1 pc(s) and weighs 0,400 kg, making it a compact, easy-to-handle component for bench or plant use. It belongs to the safety containers area of labware and complements barrels, canisters and similar vessels where a plug-in filling aid is preferred. Manufactured by Rötzmeier, the straight stainless steel design suits environments that require durable metal accessories for repeated liquid transfer. Laboratories and technical facilities can deploy it whenever a defined Ø 120 mm inlet geometry and short 120 mm height are needed for plug-in filling. This straight tunnel configuration offers a simple, robust solution for improving pour control into compatible safety containers without adding complex mechanisms to the filling workflow.
This article belongs on Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Plug-in tunnel, straight, stainl. steel, Ø 120 mm, H 120, 1 unit(s)
What is this article?
Plug-in tunnel, straight, stainl. steel, Ø 120 mm, H 120, 1 unit(s) is the article on this page. Luminix Health distributes Rötzmeier for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
