Torrey Pines Scientific EchoTherm Model CO50 programmable HPLC column chiller/heater

Torrey Pines Scientific announces its EchoTherm Model CO50 programmable HPLC column chiller/heater. The unit has a temperature range from 4 to 100°C readable and is settable to 0.1°C. The PID control software regulates temperatures to ±0.2°C, even at ambient. The product has a stable temperature LED that illuminates when the target temperature is stable to within ±0.2°C.

The Peltier-based device has five-program memory of 10 steps per program and the ability to repeat any program from one to 99 times automatically. It is suitable for chiral and biomedical chromatography where below-ambient temperatures help preserve bioactivity. It can be used for stabilising column temperatures from day to day at or near-room temperatures for repeatable results. It holds columns up to 30 cm long with 1/4″ or 3/8″ diameters in the mounting clips provided. Larger-diameter columns can be used by removing the column clips that hold the smaller columns.

The product features an RS232 I/O port for controlling the unit by a chromatograph, for programming gradients and for data collection. Also included are an injection counter, a 30-day timer with user-settable Auto-Off and a chamber drain for spills. It comes with a benchtop universal power supply for use anywhere in the world and a 3-wire AC line cord for the country of use. It is UL, CSA and CE compliant.
