Title:
AUTOMATIC METHOD AND DEVICE FOR REAGENT COMPENSATION AND STAINING INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2022/257117
Kind Code:
A1
Abstract:
A slide staining apparatus for staining of cells and tissue samples on slides before pathological analysis. The apparatus is operable to stain multiple sets of slides simultaneously and configured with a reagent system having a plurality of reagents. The apparatus includes a slide counter, a controller having a non-transitory memory component with instructions thereon, and a processor configured to determine a count of a set of received slides since the regent system was installed. When the count is below a threshold, the first protocol is used. When the count is above the threshold, slides in-progress are stained, and newly received slides are stained with a second protocol, the first protocol having an eosin reagent step followed by a 95%ethanol reagent step of a first duration, the second protocol having an eosin reagent step followed by a 95%ethanol reagent step of a second duration less than the first duration.
