At Thermic Edge, we pride ourselves on being at the forefront of the vacuum furnace industry. Providing a complete service, our bespoke versatile ranges gives you the tools necessary for any application.
Graphite Laboratory Vacuum Furnaces with graphite crucible or wafer sample hot zones for thermal processing, heat treatment, annealing & vacuum sintering.
Thermic Edge laboratory vacuum furnaces offer a range of graphite hot zones to suit a variety of uses. Our standard medium vacuum furnace with 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 Ø 150 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%.

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 provide 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 datalogging 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.
