Glass beads, solid, Ø 4 mm, AR glass are precision spherical packing elements for laboratory columns, distillation systems and general chemical apparatus. Formed as solid spheres from AR glass with a uniform diameter of 4 mm, they act as inert filler bodies that support even liquid and vapour distribution while remaining chemically resistant under typical laboratory conditions. The convenient 1 kg pack size suits both routine bench-scale work and larger preparative setups where consistent packing density is important. These beads from manufacturer Rettberg, offered under the Rettberg ® registered trademark, are classified as packing bodies (Füllkörper) and originate from Czech production. Their solid AR-glass construction provides mechanical robustness and dimensional stability, helping maintain reproducible flow characteristics in packed columns or as mixing aids. Being non-porous and free of coatings, the spheres introduce minimal background interference in many analytical and process applications. Laboratories employ such glass beads for distillation, extraction, scrubbing and as general inert packing media wherever uniform spherical geometry and glass inertness are required.

Questions about Glass beads, Ø 4 mm, solid, Soda-lime glass
What is this article?
Glass beads, Ø 4 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 Labmateriaal.
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.
