An accessory for the Scorpion Slide Preparation Robot that adjusts the cell density of blood/bone marrow samples prior to dropping chromosome slides. Centrifuged pellets in 24x 15 ml conical tubes are examined by the Bar Code Reading Station and then placed in the pipetting unit. A tray holding a 96 well microplate, a reservoir of fresh fix and a disposable tip rack is placed alongside. The Scorpion sequentially resuspends each pellet and transfers an aliquot to the microplate. The plate is removed and scanned by a microplate reader. The volume of fixative required for each tube is added by the pipetting unit to achieve a selected cell density. Normalized samples are ready for dropping or can be saved for future processing.

• Adjusts sample cell density for dropping chromosome slides on the Scorpion Robot
• Enhances metaphase spreading consistency
• Eliminates variability from “eyeballing”  tubes for cell density 
• Processes 24 samples in < 10 minutes
• Uses standard 15 ml conical tubes
