We recently had our biannual GCLP Assessment. We received a finding for not having newly assigned expiry dates on opened reagents (Cell Culture Water & DPBS). We had labeled each bottle with an opened date (signing and dating) and were using the expiry date supplied by the manufacturer.
I didn’t see any requirements stating a newly generated expiry date is required upon opening a new reagent.
Can anyone shed some light on this finding?
Thanks:)
