BioSpec Products • Cleaning or Sterilizing Your Beads

Do not acid wash beads. It is a waste of time, potentially dangerous and there are better alternatives for cleaning beads. Clean used glass or ceramic beads for reuse by soaking in a solution of laboratory detergent (the kind used to wash labware). Now and then, agitate the beads by swirling. Then rinse away all detergent with several changes of tap water and then with RO - or distilled water. Dry the beads in an open stainless steel or glass tray at 40 to 70ºC. If the dried beads …

Acid Washed Beads by OPS Diagnostics

Beads need to be cleaned prior to use, one such accepted process is to acid wash. By washing in diluted acid it helps to reduce and eliminate fine particles and contaminants. Acid washing also removes potentially deleterious heavy metals adsorbed to the surface of the bead. The beads are washed with diluted acid, beads are oven dried and baked, at which time they are suitable for most applications.

INTRODUCTION & GUIDELINES

before using. Acid washing is the most common method although heat treating removes a potential source of nuclease or nucleic acid. Also low binding beads are available that reduce non-specific binding thereby allowing more analyte to remain in suspension.
