Description
Weighing glass H × Ø 30 × 50 mm, low form, with ground stopper is a laboratory vessel designed for accurate gravimetric work with solid samples and reagents. Fabricated from borosilicate glass 3.3, it combines chemical durability with a frosted writing area (Mattschild) for clear sample identification and a precision ground stopper that provides a reliable seal. The low-form geometry measures 30 mm in height with an outer diameter of 50 mm, offering convenient access while remaining stable on the balance pan. This weighing glass from manufacturer Rettberg has a net weight of 0,051 kg, keeping tare contribution low during sensitive measurements. Supplied as a single piece, it supports routine analytical chemistry, pharmaceutical weighing and quality-control procedures where sample integrity and easy handling are essential. The robust glass construction maintains dimensional stability under normal laboratory conditions, making the vessel suitable for repeated use in research, teaching and industrial laboratories that rely on precise mass determination.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Weighing bottle, hxØ 30x50 mm, low form, stopper with standard ground joint
What is this article?
Weighing bottle, hxØ 30x50 mm, low form, stopper with standard ground joint is the article on this page. Luminix Health distributes Rettberg 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.
