The new EchoTherm Model CO50 programmable chiller/heater for high-performance liquid chromatography (HPLC) columns has a readable temperature range from 4 to 100°C and setpoint capability to 0.1°C. The control software regulates temperatures to±0.2°C, even at ambient conditions. The CO50 has an indicator LED that illuminates when the target temperature is stable to within±0.2°C. The CO50 is suitable for chiral and biomedical chromatography where below-ambient temperatures help preserve bioactivity. The CO50 holds columns up to 30 cm long with 1/4- or 3/8-in. diameter in provided mounting clips. Larger-diameter columns can be used by removing the column clips. — Torrey Pines Scientific Inc, Carlsbad, Calif.
