Suitable for use in freezing, chilling or heating biological samples from -20°C to 100°C the IC22XT is two dry baths in one, saving valuable bench space. It can run two separate temperatures and two different sample blocks at the same time. With a built-in data logger, 30-day count down timer with alarm, and RS232 interface making it can be used with robotic systems. Accessory sample blocks for 0.5ml, 1.5ml, and 2.0ml centrifuge tubes, PCR tubes and plates, 96-well and 384-well assay plates of all kinds, vials, and most sizes of test tubes can be used with this system and custom blocks are available on special order. It can be used for ligations at 14°C, maintaining 17°C for storing oocytes, enzyme reactions and deactivations, hybridizations, incubating samples above, below, or at room temperature, storing enzymes or DNA libraries, storing samples at ice bucket temperatures and much more.
