Torrey Pines Scientific’s larger EchoTherm vibration-free benchtop chilling incubators are suited for protein crystallography and other life science laboratory uses. The incubators have a 100 L capacity and are Peltier-based for heating and chilling. They have no compressors or CFC’s and are vibration-free. Applications include incubating marine samples below room temperature, enzyme reactions and deactivations, hybridizations, ligations, storing oocytes and general lab incubations. There are two models. The IN55 is fully programmable and the IN50 is simple digital. The chamber size for both incubators is 100 L. They are settable from 4.0 to 70.0 C and feature PID temperature control to ± 0.1 C, digital display to 0.1 C and accuracy to ± 0.2 C. The incubators have a RS232 I/O port for remote control and data collection, digital timer in hr, min and sec with user-settable auto off, temperature ramping on programmable models and audible alarms. The chamber size is 24 x 20 x 14”. The incubators come with eight stainless steel racks with room for twelve. Racks are split, front to back, in the middle for a variety of sample sizes.
