The CoolSafe is a versitile sample cooling system that utilizes re-chargable Cool Bricks (1°C or -10°C), anodized aluminum Cooling Chambers and triple density poly styrene Cool Box, to keep a variety of sample formats cool. Maintain sustained cold temperatures for several hours during processing or transportation. Cool Chambers are interchangable to accommodate multiple tube and microplate sizes. For maximum cooling results freeze bricks overnight: 1°C Brick in standard freezer -10°C Brick in a -80°C Freezer. Multiple Bricks can be used in rotation to maintain desired sample temperature.
