Procedure for recycling used glass beads.


  • lab dispenser soap
  • 95% Ethanol


  1. collect beads from plastic containers around the benches.
  2. soak the beads in a larger container with water.
  3. add soap and mix well.
    • this step is to remove the excess material stuck to the beads.
  4. rinse the beads with water to remove all trace of soap.
    • it helps to use a strainer.
  5. rinse the beads with the Ethanol.
    • this step removes residual water.
  6. transfer beads to glass bead jars.
    • cover loosely with lids and allow the beads to dry (overnight). autoclaving while still wet may cause the beads to develop a filmy coating.
  7. autoclave on gravity cyle, tighten lids on after cooling and store.


  1. right now we don't have a strainer to do rinse steps, I'm going to get one soon. -Kelsic
