The Model CB20 is a Peltier-based chilling/heating constant temperature small volume circulator with a temperature range from 4.0°C to 70.0°C. It can circulate up to 300 ml/minute of solution from a 1000ml reservoir for controlling the temperature of small remote samples like water-jacked cuvettes for spectrophotometers. It displays and controls temperature to 0.1°C. It is accurate to 0.1°C. The circulator has a DC operated brushless mini-pump with a variable flow control for pumping exactly the needed amount of temperature-controlled solution for small samples. The unit is very compact, takes very little bench space, and uses very little power. It has a backlit, 2-line alphanumeric display with 16 characters per line that constantly displays target the actual temperature and pumping rate. The membrane switch is used for entering temperature and pump flow rate settings. The unit has an RS232 I/O port for controlling the unit from a computer or for collecting temperature data.
The CB20 is provided with brass Swagelok fittings on the rear of the unit that accepts 1/8 inch I.D., - 1/4 inch O.D. plastic tubing. Temperature is sensed with a 3/32 inch diameter stainless steel probe provided. A six-foot long extension for the probe is available as an accessory. The temperature measurement system is 100 ohm platinum RTD for accuracy. Also, included are a 12VDC bench top power supply that takes AC inputs from 100 to 260VAC, 50/60 Hz user's manual, 3-wire AC line cord for the country of use, and full 12-month warranty.
The unit is UL, CSA, and CE compliant.
