Description
Rubber stopper No. 8 with 5/8 in opening is an accessory for Nalgene™ reusable filter holders with receiver, supplied as a rubber stopper component for vacuum-related laboratory set-ups. The stopper is designated number 8 and features a 5/8 in opening, allowing tubing or connection hardware to pass while maintaining a sealed interface. It is specified for use with the Nalgene vacuum manifold, catalogue number DS0345-0001, and forms part of the spare-parts and accessories offering for Nalgene™ reusable filter holders with receiver. Material is rubber, chosen for compliant sealing against glass or plastic necks commonly encountered in filtration and manifold work. Pack size is 3 pc(s), supporting replacement of multiple connection points or keeping reserve stoppers available beside the working manifold. From manufacturer Thermo Scientific - Laboratory Plastics, this stopper helps laboratories sustain vacuum integrity during filtration, degassing support steps, or multi-position manifold operation. Correct stopper sizing and a defined central opening simplify assembly of vacuum lines and reduce the risk of leaks that would compromise filtration efficiency. It is a straightforward consumable-style accessory for maintaining established Nalgene™ vacuum and filter-holder configurations in routine laboratory practice.

Questions about Filtration Hardware, Accessories, and Spare Parts
What is this article?
Filtration Hardware, Accessories, and Spare Parts is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
