Torrey Pines Scientific has introduced its EchoTherm Model CO50 programmable HPLC column chiller/heater. The CO50 has a temperature range from 4 C to 00 C readable and settable to .1 C. The PID control software regulates temperatures to about .2 C, even at ambient. The Peltier-based CO50 has five-program memory of 10 steps per program and the ability to repeat any program from one to 99 times automatically. It’s suitable 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. There’s a stable temperature indicator lamp on the front panel of the unit that lights when the target temperature is stable. The CO50 holds columns up to 30 cm long by ¼ in or 3/8 in diameter in mounting clips provided. Larger diameter columns can be used by removing the column clips that hold the smaller columns.
