LAUDA Viscothermostats

Thermostating in viscometry from -60 to 230 °C

LAUDA viscothermostats are the solution to thermostating all glass capillary viscometers. With their wide temperature range, the control heads of Proline and ECO meet the high requirements of viscosity measurement (ASTM D445, ISO 3105, and DIN 51562). High degree of transparency and homogeneous lighting guarantee good inspection of the measurement processes. Numerous advancement options (e.g. magnetic stirrer, additional cooler, temperature sensors, and software) optimize the range of applications possible. The new Viscocool and Viscotemp viscothermostats are sensible add-ons to the Proline PV and ECO ET. The Viscotemp models supplement the robust stainless steel thermostats with a very good price-performance ratio. The new Viscocool 6 is equipped with integrated Peltier cooling which enables thermostating at up to 15 °C below room temperature in compliance with standards.

Application examples

  • Standard-compliant thermostating of different models of glass capillary viscometers
  • Thermostating of automatic viscometers as all-around systems
  • Manufacture of dilution series with magnetic stirrers

Proline Viscothermostats

LAUDA viscothermostats are optimized for directly observing inserted objects. The temporal and spatial temperature stability required for precisely determining the viscosity is guaranteed for the full temperature range. As such, they are ideal for use with the fully automated LAUDA PVS or iVisc viscometers. Thanks to the double-chamber principle, a constant liquid level in the measuring room is guaranteed regardless of the rate and temperature. The PVL models are equipped with five layers of insulating glass and by connecting a DLK 45 through-flow cooler or Proline RP 890 cooling thermostat are suited to low-temperature measurements down to -40 or -60 °C.

Viscocool and Viscotemp Viscothermostats with transparent bath and Silver and Gold control heads

The tried-and-tested ET 15 baths made from polycarbonate provide space for immersion of a maximum of three glass capillary viscometers for manual measurement using the stop watch or for up to two automatic measuring stations for iVisc or S 5 (PVS). If required, when using dilution viscometers for example, up to two magnetic stirrers can be added to the thermostat. Specifically for applications near room temperature (15 to 30 °C), the ET range was expanded upon with the inclusion of the extremely compact, electronic Viscocool 6 version which is cooled using Peltier technology. It can provide cooling without a cooling water connection or any additional devices. The similarly new round solid glass bath Viscotemp 18 is used particularly for temperatures around 100 °C for operation with silicone oils and with aggressive samples. Outstanding insights in the smallest space can be achieved thanks to up to five stop watch measuring stands. Alternatively, it can be equipped with an iVisc or PVS measuring stand and thermostating position.

Viscotemp Viscothermostats with stainless steel bath and control head Silver and Gold

The new Viscotemp 15, 24, and 40 viscothermostats with high-quality stainless steel baths and glass windows can be used in the most common temperature range from 0 up to 105 °C. The clearly designed singlechamber systems with optional background lighting provide a glass-clear view and can be easily cleaned. They are ideal for determining, for example, the viscosity index of motor oils or the solution viscosity of plastics. The Viscotemp 15 type offers space for up to four manual maesuring stations or two automatic measuring stands, iVisc or S 5 (PVS). Viscotemp 24 has space for seven viscometers or up to four automatic measuring stands. Both versions can be fitted with cleaning modules. Viscotemp 40 was designed exclusively for manual measurements with twelve measuring stations. With the Therm 180 heat transfer liquid, the thermostats can be operated as a corrosion-resistant thermostating bath for aggressive samples, e.g. for polyamides dissolved in sulfuric acid.
