Quickly freeze samples at -1°C per minute with this chilling jar from Heathrow Scientific. The True North® jar is filled with alcohol to speed the freezing rate of cryogenic vials. Easily fill jar to visible liquid level graduation with isopropyl alcohol. Samples are not in contact with liquid— an insert provides barrier while alcohol is securely contained. When samples are removed from the freezer, the insulating foam holder decreases warming rate and extends working time.

Stack in freezer or on benchtop. Includes polycarbonate jar, high-density polyethylene lid and insert, and polyurethane foam holder. Measures 123 x 105mm D x H.
