KRÜSS Optronic 1Peltier thermostat PT31 The PT31 circulation thermostat is equipped with high-performance functions. The device is ideally suited for applications requiring a temperature range at a constant level. The robust locking mechanism of the PT31 provides a sturdy connection and ensures constant temperature control of the medium. The compact and sturdy design does not require much space and can be placed anywhere in the laboratory. Technical data: Temp. control range: 8 – 35°C Accuracy of temp. control: ± 0.2°C Temp. control resolution: 0.1°C Electrical data: 100 – 240 V AC, 1.3 A, 50/60 Hz Dimensions (W×H×D): 108 × 199 × 145 mm Weight: 1.5 kg Article Order No. Peltier thermostat PT31 65 61 20031 for refractometers/polarimeters 2Circulating thermostat PT80 The PT80 circulation thermostat is an extremely quiet, energy-efficient and handy device that has been specially developed for small temperature control tasks in the laboratory. Fast temperature control is also possible due to the low filling volume of only 250 ml. With an accuracy of ±0.1°C, the PT80 is ideally suited to high laboratory standards for the temperature control of polarimeters and refractometers. The PT80 is also very well equipped for efficient and environmentally friendly cooling of condensers (e.g. Liebig or reflux condensers) in thermal separation processes on a laboratory scale. Technical data: Temp. control range: 5 – 80°C Accuracy of temp. control: ± 0.1°C Temp. control resolution: 0.1°C Pump capacity: 60 l/h Pump pressure: 110 mbar Cooling capacity at 20°C: 40 W Heating capacity: 120 W Electrical data: 100–240 V AC, 2.5 A, 50/60 Hz Dimensions (B×H×T): 170 × 225 × 244 mm Weight: 2.7 kg Article Order No. Circulating thermostat PT80 10 61 10080 webcode WW18A011 3 4 LAUDA Loop – Thermoelectric circulation thermostats, LAUDA The device line LAUDA Loop comprises two thermo-electrical (Peltier) circulation thermostats for external temperature control. The thermostat is intended for laboratory applications such as temperature control of refractometers, polarimeters, electrophoresis chambers, or small bioreactors. • Small footprint • Energy efficient • No cooling agent required • Heating and cooling with the same component, high control accuracy of ±0.1 K • RS-232 interface integrated as a standard • Requires little maintenance • Low weight • Little vibration, quiet operation • 3-button control with bright, high-contrast OLED display • One voltage variant for world-wide use: 100 – 230 V; 50/60 Hz Technical data: Temperature range: 4 – 80°C Temperature accuracy: ± 0.1 K Type Cooler capacity at 20°C kW Heating capacity kW W × D × H mm Order No. 3L 100 0.1 > 0.1 175×300×265 10 23 39100 4L 250 0.25 > 0.25 260×370×315 10 23 39250 Heating Units, Refrigerating Units Temperature Controllers
