Torrey Pines Scientific, Inc announces its new EchoTherm Model CO50 Programmable HPLC Column Chiller/Heater. It is ideal for chiral and biomedical chromatography where below-ambient temperatures help preserve bioactivity. It can be used for stabilizing column temperatures from day to day at or near room temperatures for repeatable results. It has a temperature range from 4.0°C to 100.0°C readable and settable to 0.1°C. The PID control software regulates temperatures to ±0.2°C, even at ambient. 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 5-program memory of 10 steps per program and the ability to repeat any program from 1 to 99 times automatically.
