Beckman Coulter LS Control GB500 Glass Bead Sample Standard 2x Full 1x Used
PLEASE NOTE that one of the bottles has been opened and only contains ~7g of sample. The other 2 bottles are full and have not been opened.
Testing Included loading 5.94g of GB500 into a Beckman Coulter LS 13 320 ALM Module followed testing the sample. This produced the following results:
d10: um/ d50: um/ d90: um
All three measurements fell within the acceptance limits printed on the supplied Beckman Coulter assay sheet as seen in photos #7 & 9. Despite being "expired", these standard beads perform well.
