Liebisch Metal Block Thermostats

High quality, durable German made block thermostats, to suit many applications.

Special bespoke units can be supplied.

A large number of thermal analysis methods can be performed with Liebisch metal block thermostats. Disintegration, hydrolization, incineration, evaporation or CSB are examples.

Category: Brands: .

Units are available with integrated controller or with a separate control box.

The block is produced from a single piece of special aluminium alloy, leading to high temperature stability and short response times.

A standard feature of the thermostats is the PID controller with set point and actual value display. The units can be equipped with the integral Digit (for maximum temperature stability) or with the external control box (for safe operation).
The controller can perform timer or ramp functions. Optional intel® RS 485 interface to connect to a PC. The controller can be programmed independently using special software.

  • Temperature range. AT to +130°C
  • Heating power: 600 W
  • Operating voltage: 230 V
  • Housing dimensions W x D x H:  260 x 180 x 120 mm

Evaporator

The Evaporator combines a metal block thermostat with a gasing unit, the Multiplex-Valve-Unit. The patented system allows heating and concentrating of samples with selected gases. Easy-to-operate individual gas control valves allow targeted gasing of individual samples. The valve unit is height-adjustable and can be swivelled to the side. As an option the support rod can be supplied with a hand-wheel to adjust the height.

  • Sample places: 32, 56, 60
  • Bore hole diameter: 5 to 18 mm
  • Temperature range: AT to +200°C
  • Heating rate: 10 K/min.
  • Heating power: 750 – 1100 W
  • Operating voltage: 230 V
  • Housing dimensions W x D x H:  350 x 230 x 130 or 450 x 230 x 130 mm

Multivario

Up to 20 different functions can be performed by the Multivario, e.g. nitrohydrochliric acid disintegration, cyanide or mercury disintegration.
