  • Annealing, Hardening and Brazing Furnaces N 7/H – N 87/H

    To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The N 7/H – N 87/H models are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.

  • Differential Thermal Analysis DTA PT1600

    The DTA uses a dynamic measuring principle. This instrument will measure endothermal and exothermal heat flow between the sample and reference (enthalpy).
    In general these heat flows are characteristic of chemical or physical changes of the sample. The test sample and an inert reference material are heated simultaneously in the same atmosphere.
    Both the sample and reference material temperatures are measured with thermocouples.
    Then these 2 thermocouple output voltages are subtracted from one another. There suit is a low voltage signal which is proportional to the endothermal and exothermal reaction.
    Endothermic sample reactions absorb heat and exhibit a lower sample temperature when compared to the reference material.
    Exothermic reactions produce heat and exhibit a higher sample temperature when compared to the reference material.
    Options include operations in vacuum and inert atmospheres

  • FURNACES – High Temperature 1400°C, 1500°C & 1600°C Laboratory chamber furnaces (RHF)

    Maximum operating temperatures of 1400°C, 1500°C & 1600°C with chamber
    capacities of 3, 8, 15 & 35 litres. These furnaces are heated by powerful silicon
    carbide elements located on both sides of the chamber that ensure good thermal
    uniformity (silicon carbide elements can withstand the stress of everyday operation and provide good longevity).
    Hardwearing refractory brick in chamber entrance and hearth provide good resistance to abrasion whilst elsewhere, lightweight ceramic fibre insulation is used which ensures good energy efficiency and rapid heating. A vertical counterbalanced door keeps hot door insulation away from operator whilst a positive break door safety switch isolates the chamber from the power supply, when the door is opened.
