Thermic Edge laboratory vacuum furnaces offer a range of graphite hot zones to suit a variety of uses. Our standard medium vacuum heat treating furnace with a crucible size of Ø102 x 51mm has a maximum temperature of 2100˚c. We also offer an alternative deeper medium-hot zone size of Ø60.5 x 75mm, a larger size of Ø150 x 75mm, and an extra-large hot zone size of Ø180 x 140mm. We also offer flat wafer hot zones for Ø 4”, Ø 6” and Ø 8” sample sizes.
The cylindrical graphite elements are extremely efficient and allow for fast ramps, extremely stable, and using a dual hot zone improves temperature uniformity a deviation of < +/- 1%.
We also specialise in meeting the requirements of our customers with custom options for their system designed specifically for their needs and applications.
Furnaces use CCC elements in graphite zones to heat both large-diameter samples and smaller pieces in a susceptor plate. Options from 4” to 8”, including dual zone for 8”.

Gas flow is manually regulated via needle valves. Chamber pressure is controlled using a vacuum Speedi valve.
Eurotherm Nanodac handles data logging and temperature regulation. External PC connection is supported for process analysis and repeat cycles.
All power feedthroughs and chamber exteriors remain cool due to full water cooling, enabling extended use.
Thermic Edge laboratory vacuum furnaces are designed for high temperature material processing in vacuum, inert gas and controlled atmosphere conditions. Depending on the furnace configuration, process temperature, atmosphere and sample material, laboratory vacuum furnaces can support a wide range of thermal processes, including vacuum brazing, sintering, annealing, degassing, drying, tempering, soldering, hardening, selected quenching applications, Metal Injection Moulding (MIM), Ceramic Injection Moulding (CIM), metallisation, liquid silicon infiltration and carbonisation.
These processes often require stable heating, reduced oxidation and precise control of the furnace environment. The graphite hot zone provides efficient high temperature performance, while vacuum pumping, gas handling and temperature control options allow each system to be configured around the needs of the material, sample size and process route.
| Vacuum brazing and soldering | Suitable furnace configurations can support joining processes such as vacuum brazing and soldering where controlled heating, atmosphere control and reduced oxidation are required. |
| Sintering, MIM and CIM | Laboratory vacuum furnaces can be configured for selected sintering processes, including Metal Injection Moulding (MIM), Ceramic Injection Moulding (CIM) and related powder processing routes. |
| Annealing, hardening and tempering | Vacuum annealing, hardening and tempering processes can benefit from stable temperature control, vacuum conditions and inert gas processing where material compatibility allows. |
| Degassing and drying | Degassing and drying applications use controlled heating and vacuum conditions to remove trapped gases, moisture or volatile material from selected samples and components. |
| Metallisation and surface processing | Metallisation and related surface processes may require high temperature treatment in vacuum or controlled atmosphere conditions, depending on the material and process requirements. |
| Liquid silicon infiltration and carbonisation | Liquid silicon infiltration and carbonisation applications require careful control of temperature, atmosphere and material compatibility. Thermic Edge can advise on suitable laboratory vacuum furnace configurations for these specialist processes. |
| Selected quenching applications | Quenching requirements vary by material and cooling profile. Thermic Edge can advise whether a laboratory vacuum furnace configuration is suitable for the required heat treatment process. |

Thermic Edge laboratory vacuum furnaces are suitable for high temperature vacuum and atmosphere processing applications, including sintering, brazing, annealing, degassing, carbonisation, metallisation, and advanced materials research.
They are designed for users who need stable thermal performance, controlled processing conditions, and flexible system configuration. For wider furnace options, see the Thermic Edge vacuum furnaces range.
Thermic Edge laboratory laboratory vacuum furnaces are available with standard operating temperatures up to 2100°C. A 3000°C all graphite hot zone option is also available for specialist high temperature applications.
The right temperature specification will depend on the material, process atmosphere, hot zone size, sample geometry, and required thermal cycle.
Yes, our furnaces can be configured for different sample formats, including crucibles, wafers, and flat samples. Wafer heating options are available for 4 inch, 6 inch, and 8 inch sample sizes.
This flexibility is useful for research laboratories, universities, manufacturers, and development teams working with different materials, sample shapes, or process requirements.
The laboratory furnaces can be configured with different hot zone sizes, pump options, gas inputs, power supplies, water chillers, pyrometers, thermocouples, and control systems.
Custom configuration helps ensure the furnace matches the required operating temperature, vacuum level, process atmosphere, sample size, and production or research workflow. Related heating technologies are also available through Thermic Edge graphite heating elements.

For wafer sample testing our laboratory vacuum furnaces use a CCC element enclosed in a graphite hot zone to heat both individual large Dia. samples and smaller samples held in a susceptor plate.
Wafer sample furnaces range from 4” to 8” Dia sample size, with dual zone option on 8”.
3000˚c laboratory furnace uses the same footprint as the standard furnace but incorporates a few changes.
Thermic Edge’s range of laboratory vacuum furnaces provides a user-friendly interface promoting their ease of use via modern touchscreen HMI display which allows control of all furnace pumping, gas processing, and venting features. With multiple screens for operation, interlock displays and mimic with valve states.
The HMI allows the user to control the automated pump down sequence which is designed to remove residual oxygen from the chamber and intern increasing the life of the hot zone and avoiding the possibility of oxidation occurring.
Two independent gas inputs are also controlled via the arm-mounted HMI with their individual flows manually adjusted, via needle valves, to the user’s requirements. Pumping speeds are also regulated manually via a vacuum Speedi valve mounted on the front of the vacuum furnace, enabling manual control of chamber pressure and gas flow rates.
Temperature and data logging are controlled via a Eurotherm Nanodac PID temperature controller/data logger which can be connected to a remote PC for data analysis. Software is provided to allow for multi-step process cycles to be programmed allowing for simple repeat testing and easy adjustment to programs.
The fully water-cooled vacuum chamber and power feedthroughs keep the exterior of the chamber at ambient temperature and preventing overheating, allowing for extended periods of operation.
All laboratory vacuum furnaces require an electrical supply, chilled water supply, and drain, Argon gas for venting, process gas supplies, and exhaust line.
