2.5mm diameter borosilicate glass beads packed in 500g jars. Beads thrice before packing washed in distilled water. These beads are designed for use in dry glass bead sterilizers that are used to sterilize small instruments. Dry glass beads can be heated up to 250°C. Inserting clean instruments into a glass bead completes the sterilization process, killing all microorganisms, including spores, in less than 10 seconds.
2.0+/-0.3mm precision beads. The borosilicate material is made from natural silicate sand and raw materials (not recycled crushed glass), heavy metal free. These glass beads provide high heat resistance. Resistance to temperature difference. They have a low coefficient of thermal expansion. High corrosion resistance, and suitable for daily heating in glass bead sterilizers.
