Carbolite EVZ 12/450B Three Zone Vertical Split Tube Furnace is designed to be compact and versatile. The furnace is supplied with a stand providing vertical or horizontal use. Supplied without work tube. All furnaces in the EVZ range can accept a maximum 60mm outer diameter work tube. Maximum temperature 1200C, continuous operating temperature 1100C. Heated length is 450mm. Uniform length is 338 mm plus or minus 5c. Maximum power consumption is 2000 watts. Heat up time 58 minutes.

Carbolite Gero EVZ is a 3 zone vertical bench mounted furnace. The end zones are heated independently reducing temperature differential across the heated length giving excellent uniformity. The furnace splits into two halves by hinges allowing the furnace to be opened, removing the need to insert tubes by narrow end holes. Makes changing work tubes easy and used where larger protruding ends do not fit into the end holes of a standard tube furnace. Adaptors allows the flexibility of accepting tubes lower than the maximum overall diameter into the furnace.

The PID 301 controller is separated from the furnace by a 2 metre conduit, with process timing and one ramp rate features. Options allow 8 or 20 segment programming with storage.

The furnace heats using free wire radiating elements integrated into the insulation, this protects the elements and using a separate tube restricts contamination of the elements. Insulation is high graded vacuum formed giving high efficiency heating. Around the furnace perimeter mesh is fitted to guard the operator.


  • Over temperature protection used if furnace has expensive contents or is left unattended for large periods of time.
  • Work tubes varying lengths and diameters and materials – shock and chemically resistant.
  • Insulation plugs, Work Tube Seals  & Radiation shields to increase uniformity, combat heat loss and for atmosphere retention
  • Pumps are offered for vacuum application: rotary vane pump or turbo molecular pump.
