Description
The laboratory glass beads sized 2.3–3 mm are produced under ISO 9001 certified manufacturing systems to ensure uniform size, high thermal stability, and reliable performance during sterilisation and dry-heat applications. Each bead is made from borosilicate-based glass that aligns with ASTM E438 and ISO 3585 quality expectations for laboratory-grade glass, providing excellent resistance to thermal shock, heat cycling, and chemical exposure. Their consistent spherical geometry supports even heat distribution, making them highly effective for sterilising forceps, scalpels, inoculating loops, and other small instruments in dry bead sterilisers.
Engineered for long-term durability, the beads maintain structural integrity and thermal conductivity across repeated high-temperature cycles, supporting rapid and uniform heat penetration. Their non-porous surface prevents moisture retention and reduces contamination risk, ensuring dependable sterilisation in microbiology labs, tissue culture rooms, educational facilities, and research environments. The beads also provide excellent heat retention for block heaters, oil baths, and bead bath systems, offering a clean and low-maintenance alternative to liquids or sand.
Supplied by LabChoice Australia, these laboratory glass beads are widely used in university laboratories, teaching facilities, research institutes, and industrial R and D environments across Australia. They are suitable for distillation, reflux, solvent evaporation, and general laboratory heating applications where controlled boiling, safety, and repeatable results are essential.
