Description
Glass beads, solid, Ø 2 mm, AR glass are solid spherical packing bodies made from AR glass for laboratory and process applications. These beads serve as inert Füllkörper in distillation columns, absorption towers, support layers and reaction vessels where chemically resistant media of defined geometry are required. The 2 mm diameter supports uniform packing density and controlled flow characteristics, helping reduce channeling in packed beds. Supplied in a 1 kg pack from manufacturer Rettberg, they offer mechanical stability under typical laboratory flow conditions. Net weight is 1,000 kg. AR glass provides resistance suitable for many aqueous systems and selected organic media commonly encountered in chemical and analytical work. Laboratories use these solid glass beads to create reproducible beds that improve mass-transfer or separation efficiency. The product carries the Rettberg ® trademark and originates from the Czech Republic. Ideal for chemical, pharmaceutical and research environments needing durable, inert packing materials with consistent particle size for reliable column and process performance.

Questions about Glass beads, Ø 2 mm, solid, Soda-lime glass
What is this article?
Glass beads, Ø 2 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.
