Torrey Pines Scientific EchoTherm CB20 Constant Temperature Chilling/Heating Mini Circulator

DISCONTINUED ITEM

The 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 a solution up to 300 ml/minute from a 1000 ml reservoir for controlling the temperature of small remote samples like water-jacked cuvettes for spectrophotometers. The CB20 displays and accurately controls temperature to within 0.1°C

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. A six-foot long extension for the probe is available as an accessory. The temperature measurement system is 100 ohm platinum RTD for heightened accuracy. Also included are a 12 VDC bench top power supply that takes AC inputs from 100 to 260 VAC, 50/60 Hz user’s manual, 3-wire AC line cord for the country of use and full 12-month warranty

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, taking up minimal 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 also has an RS232 I/O port for controlling the unit from a computer or for collecting temperature data.
