Background information
MACS® Chill Racks can be used in combination with the autoMACS® Pro Separator, the MACSQuant® Analyzer and also for manual sample handling steps.
The Chill Racks are pre-cooled in the refrigerator (2–8 °C). The special coolant contained in the racks switches from fluid to solid at 8 °C and maintains a low temperature until the coolant is completely melted. The phase switch is visible. Do not cool racks below 0 °C as cell samples may freeze!
MACS Chill Racks are available as single racks and sets of three.
Chill 5 Rack contains 24 slots for 5 mL tubes and can be used for cell separations of up to 6 samples.
Chill 15 Rack contains 15 slots for 15 mL tubes and 5 slots for 5 mL tubes. It can be used for cell separations of up to 5 samples.
Chill 50 Rack contains 6 slots for 50 mL tubes, 3 slots for 15 mL tubes, and 3 slots for 5 mL tubes. Up to 3 cell samples can be handled with a Chill 50 Rack.
