Glass Beads

Glass Beads

Glass beads are widely used for cell lyses in various homogenization processes of biological samples. Our glass beads are extremely round, lead free and have a narrow size spread which makes them extremely durable for a variety of homogenization processes.

Washing & Sterilization
Glass beads are washed twice in sterile water and dried at 350˚F for three hours.
Dried beads are packed in 50 gm and 100 gm quantities and are sterilized
at 120˚C for 15 minutes.
