The completely solid-state EchoTherm™ IC22 2-Position Electronic Chilling/Heating Dry Bath is versatile, reliable and easy to use. Each heating/chilling station has its own Peltier module, and the entire unit has only two moving parts: the fans. 
 
Each plate can be set separately for any temperature within the range of unit without interaction between the plates. The IC22 has simple digital controls and a two-line alphanumeric digital display that is backlit for easy viewing. The display shows the target and actual temperatures of both plates. 
 
The chilling/heating surfaces are each 2.875” (7.3 cm) x 4.375” (11.1 cm) aluminum plates that are very flat for optimal contact with the sample blocks. When unloaded, the plates will reach below 0 °C in under two minutes. They will heat to 37°C in under a minute. The chilling and heating rates will change with loads. For instance, temperatures to 4.0°C can be reached on sample blocks as large as 4” (10.2 cm) x 3” (7.6 cm) x 6” (15.2 cm) in about 30 minutes. 
 
Units come complete with bench-top power supply, instruction manual and AC line cord. Sample blocks and covers are available as accessories and are shown on the price list.
