Torrey Pines Scientific, Inc., presents its EchoTherm Model CO50 Programmable HPLC Column Chiller/Heater.
The unit 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 chiller/heater has a Stable Temperature LED that illuminates when the target temperature is stable to within ±0.2°C. Furthermore, the Peltier-based CO50 has 5-program memory, entailing 10 steps per program and the ability to repeat any program from 1-99× automatically.
According to the company, this technology is ideal for chiral and biomedical chromatography in which below ambient temperatures help to preserve bioactivity. It can be used for stabilizing column temperatures from day-to-day at or near room temperatures for repeatable results. The CO50 holds columns up to 30 cm long by 1/4” or 3/8” diameter in mounting clips provided. Larger diameter columns can be used by removing the column clips.
The device features RS232 I/O port for controlling the unit by a chromatograph for programming gradients and data collection. Also included are an injection counter; 30 day timer with user settable auto-off; and a chamber drain for spills. The unit comes with a benchtop universal power supply for use anywhere, 3-wire AC line cord, 12 month warranty and an instruction manual. Finally, the CO50 chiller/heater is UL, CSA and CE compliant.
