EchoTherm vibration-free, benchtop chilling incubators are available in two 100-liter models and are designed for protein crystallography and other life science laboratory uses. The IN55 is fully programmable, while the IN50 is simply digital. Both models can be set from 4.0ºC to 70.0ºC and feature PID temperature control to ± 0.1°C, digital display to 0.1ºC, and accuracy to ± 0.2ºC. The incubators have an RS232 I/O port for remote control and data collection; a digital timer with hour, minute, and second display; an auto-off feature; temperature ramping on programmable models; and audible alarms. The chamber size is 14 inches wide x 24 inches high x 20 inches deep and comes with eight stainless steel racks, with space available for up to twelve. Universal power supplies accept AC line inputs from 100VAC to 265VAC.
