Product Description:

The completely solid-state EchoTherm™ IC50 Digital Electronic Chilling/Heating Dry Bath is compact, versatile, reliable and easy to use. Simply use the UP or DOWN arrows on the front panel membrane switch to set the temperature desired and the unit will go to that temperature.

The chilling/heating surface is a 2.875” (7.3 cm) x 4.375” (11.1 cm) aluminum plate that is very flat for optimal contact with your sample. When unloaded, the plate surface will reach below 0°C in under two minutes. It will also heat to 37°C in approximately 2 minutes. This rate of chilling or heating may vary with the load on the plate. For instance, temperatures down to 4.0°C can be reached on a solid aluminum block as large as 4” (10.2 cm) x 3” (7.6 cm) x 6” (15.2 cm) in less than one hour. When insulated, these large blocks can be driven below 0°C. Temperature gradients from the center to the edge of any aluminum block mentioned will be less than 0.3°C at any temperature.

A sample cover is available for assay plates or aluminum blocks and other samples. These blocks and covers are available as accessories.
