Description
Glass beads, reflex beads made of soda-lime glass with a diameter of 1,7–2,0 mm provide a coarser spherical medium for laboratory boiling and packing applications. Packed as 1 kg, the beads have a density of 2,5 g/cm³ and a smooth, consistent geometry that supports even heat distribution in flasks and vessels. As boiling aids they promote steady bubble nucleation, reduce bumping risk and assist mixing during distillation, evaporation and general wet chemistry. The 1,7–2,0 mm size is practical where larger beads are easier to handle, recover or separate from reaction mixtures after use. Soda-lime glass offers suitable chemical durability for everyday aqueous work and many common organic solvents under standard lab conditions. These reflex beads from manufacturer ROTH SELECTION align with labware categories for boiling pebbles, glass beads and related aids. The 1 kg pack size suits routine replenishment of shared stocks. Choose this diameter when a more open packing structure and robust bead size are desired for controlled heating workflows.
This article is part of Laboratory cleaners & detergents, in Cleaning & disinfection.

What is this article?
Glass beads, reflex beads, made of soda-lime glass, Ø 1.7 - 2.0 mm, 1 kg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Laboratory cleaners & detergents, inside Cleaning & disinfection, in Lab safety equipment.
A laboratory cleaner removes soil, grease and residues from glassware and benches. Phosphate, surfactant and whether it is for a machine or for the hand are the differences. A cleaner is not a disinfectant unless a biocidal claim is printed, with a contact time.
Cleaning removes soil. Disinfection kills or inactivates microbes that remain. They are not the same step, and a disinfectant on top of dirt does less than the label claims. The spectrum, the contact time and the surface decide the product. A wipe is the mechanical half of the same job. Chemical classification is on ECHA. Workplace practice is EU-OSHA on dangerous substances. Biosafety context is the WHO biosafety topic.
