For all basic tasks of temperature control in the laboratory

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. Unlike classic compressor-driven thermostats, the PT80 uses modern Peltier technology to operate thermoelectrically.
The environmentally friendly technology ensures extremely quiet and low-vibration operation, 50% lower energy consumption and completely eliminates the need for refrigerants. Yet rapid temperature control in a temperature range from 5 °C to 80 °C is still possible, not least 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 effcient and environmentally friendly cooling of condensers (e.g. Liebig or reflux condensers) in thermal separation processes on a laboratory scale.

Your benefits:

  • Circulation thermostat with Peltier technology
  • Rapid temperature control from 5 °C to 80 °C
  • Temperature accuracy of ±0.1 °C
  • Extremely quiet and low-vibration operation
  • Environmentally friendly, due to 50% lower energy consumption and elimination of refrigerants
  • Suitable for operation with non-flammable liquids (water or water/glycol mixture)
  • Resistive touchscreen display
  • Easy-to-understand and intuitive menu navigation
  • Standard RS-232 interface for PC communication
  • PT80 control by P8000 series polarimeter
Applications

Typical applications

  • Temperature control of small sample volumes in analytical laboratories, chemical laboratories, life science
  • Temperature control of refractometers, polarimeter tubes and viscometers

Discover the benefits of our circulating thermostats

The circulation thermostats PT80 and PT31 are the smallest thermostats in the world for temperature control tasks in the laboratory. They have been designed for the temperature control of small sample quantities. It was important for us that they were user-friendly, offered a wide spectrum of applications and enabled a pleasantly quiet working environment.

Digital functions

The easy-to-understand TFT display enables all relevant information to be clearly displayed. The temperature of the PT80 can be individually adjusted via a user-friendly touchscreen. The easily accessible functions and intuitive user guidance in the user menu ensure convenient handling.
The circulation thermostat can be easily controlled with the serial RS-232 interface. This enables effective data exchange as well as remote control via PC or direct control via the user interface of our Polarimeter P8000 series. PC networking also provides documentation of all relevant settings. The temperature of the PT80, for example, can be queried with the simplest programs. These  networking functions even make the PT80 suitable for automated temperature control in the environment of laboratory 4.0 applications.

Temperature control of Abbe Refractometer AR2008

The PT80 circulation thermostat is often used for the sample temperature control of Refractometer AR4. The Abbe refractometer AR2008 can achieve highly accurate and extremely reproducible measurement results completely independent of the ambient temperatures. PT80 circulation thermostat is extremely small and can be very easily connected to all water-temperable refractometers.

Temperature control of Polarimeter P8000-T

When used in combination with polarimeters, the PT80 circulation thermostat ensures uniform temperature control of the samples to be measured. This enables highprecision and reproducible measurements, such as those prescribed by different standards in the pharmaceutical industry at 20 °C or 25 °C.
