Aerospray StatWescor - Elitech Group
PRET LA CERERE
Aerospray provides many advantages over hand staining or automated dip type stainers, including speed, economy, consistent performance, and no cross-contamination.
The ELITech PSmears are automatically fixed with methanol or with Aerofix® fixative at the beginning of the staining cycle (alternatively, slides can be hand-fixed using methanol or Basofix®).
After a drying sequence, eosin stain is applied to stain acidophilic cell components, followed by a brief period for stain penetration. Thiazin dye is then applied to stain the basophilic cell components, followed by another brief stain penetration period.
A buffered rinse cleans the slides of excess stain and is then removed by centrifugation. Slides are dry and ready for the microscope at the end of the cycle.
Slides are exceptionally clean. Most fields are literally free of precipitation or stain debris.
THE ROMANOWSKY STAIN
The Aerospray Stainer uses a two-part aqueous Romanowsky stain. Its principal advantages are:
RAPID STAINING KINETICS
Blood smears are fixed, stained, and dried in about 4 minutes.
IMPROVED STAIN STABILITY
The slow rate of decomposition of thiazin and eosin dyes in sepa- rate neutral aqueous solutions allows a long shelf life. Since changes in the stains occur very slowly, staining results are highly reproducible and consistent.
Since there is virtually no stain precipitation or debris, slides are exceptionally clean.
All ELITech hematology reagents can be prepared from concentrate to help defray shipping costs and to satisfy specific customer needs, such as neutrophil and overall color preferences.
With aqueous stains, basophil granules, which are water soluble, may be washed away in the staining process, but with experience, degranulated basophils are readily recognized.
For customers who prefer granulated basophils, Wescor offers Basofix fixative. This specially compounded formula yields stain coloration more reminiscent of alcohol-based stains. In addition to fixing basophil granules, primary granules are also strengthened.
