Description
Glass beads, solid, Ø 5 mm, AR glass are precision spherical packing elements intended for laboratory columns, distillation systems and general chemical apparatus. Manufactured as solid spheres from AR glass with a uniform diameter of 5 mm, they serve as inert filler bodies that promote even distribution of liquids and vapours while remaining chemically resistant under standard lab conditions. Supplied in a practical 1 kg pack, the beads support both everyday bench work and larger preparative installations that demand consistent packing density. These glass beads from manufacturer Rettberg, marketed under the Rettberg ® registered trademark, are designated as packing bodies (Füllkörper) and are produced in the Czech Republic. The solid AR-glass construction delivers mechanical strength and dimensional stability, aiding reproducible flow behaviour in packed columns or as mixing media. Non-porous and uncoated, the spheres minimise unwanted background effects in many analytical and process uses. They are well suited to distillation, extraction, scrubbing and other applications that benefit from uniform spherical geometry combined with the inertness of glass.

Questions about Glass beads, Ø 5 mm, solid, Soda-lime glass
What is this article?
Glass beads, Ø 5 mm, solid, Soda-lime glass is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
