Torrey Pines Scientific Inc, Carlsbad, Calif, has released the EchoTherm model CO50 programmable high-performance liquid chromatography column chiller and heater, suited for chiral and biomedical chromatography where below-ambient temperatures help preserve bioactivity. To achieve repeatable results, the device can be used to stabilize column temperatures from day to day at or near room temperatures. It has a temperature range from 4.0°C to 100.0°C, readable and settable to 0.1°C. The proportional–integral–derivative control software regulates temperatures to ±0.2°C, even at ambient temperatures. The CO50 has a stable-temperature LED that illuminates when the target temperature is stable to within ±0.2°C. The Peltier-based CO50 has a five-program memory that can include up to 10 steps per program, and the ability to repeat any program from 1 to 99 times automatically.
