Description
Replacement stopper type Pennyhead is a dedicated spare stopper for BOD-bottles used in volumetric analysis and oxygen-bottle applications. The Pennyhead design provides a familiar handling form for laboratories that need reliable replacements when original stoppers are worn, damaged or missing from BOD bottle sets. Each pack contains 12 pc(s), a convenient quantity for maintaining spare stock beside active oxygen bottles and volumetric glassware. The pack weight is 0,470 kg, supporting straightforward storage and inventory control in busy analytical environments. These replacement stoppers are from manufacturer DWK Life Sciences and are specified for BOD-bottles within laboratory glass, vessels and consumables ranges. They suit water-quality, environmental and teaching laboratories that perform biochemical oxygen demand work and related dissolved-oxygen procedures. Keeping Pennyhead-type spares on hand helps minimise downtime when bottles must remain sealed during incubation or measurement sequences. This 12-piece pack integrates cleanly into existing BOD-bottle setups and volumetric analysis equipment inventories without changing established laboratory practice.

Questions about Replacement stopper type Pennyhead, for BOD-bottles, 12 unit(s)
What is this article?
Replacement stopper type Pennyhead, for BOD-bottles, 12 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
