LAUDA PTT – Peltier Thermostat for Tensiometers

Product Details

The LAUDA PTT is among the smallest laboratory thermostats in its class. It contains control and operation electronics, heat flow elements and a mini magnetic stirrer. Thanks to its small dimensions, the thermostating unit is suited to use in the new LAUDA TD 3 Tensiometer and for stand-alone applications as well as in combination with other analytical equipment.

Examples for applications in stand-alone operation

  • Thermostating/stirring small quantities of liquid in volumetric flasks, bottles and open or covered beakers
  • Cyclical thermostating of biological or chemical samples
  • Sample preparation of polymers and biochemical products as well as the solution of salts and crystal growing
  • Dispersing, emulsifying, homogenising

Examples for applications in combination with other analytical equipment

  • Dynamic viscosity measurements
  • Density measurements by buoyancy or oscillating U-tube
  • Photometric and turbidity measurements
  • Dynamic measurements of light scattering
  • Titration
  • pH-value measurements
  • Conductivity measurements
  • Measurement of ion concentration
  • Oxygen partial pressure measurements
