Tube Furnaces High Temperature 3 Zone

Tube Furnaces High Temperature 3 Zone

Carbolite | Sample Preparation - Inorganic

The TZF 3-zone high temperature tube furnaces are available at 1500 °C, 1600 °C, 1700 °C and 1800 °C The heated length is divided into 3 zones.

An extended uniform zone in the mid-section of the work tube is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.

Key Features:

  • 1500 °C and 1600 °C models have silicon carbide heating elements
  • 1700 °C and 1800 °C models have molybdenum disilicide heating elements
  • Accepts work tubes with maximum outer diameters up to 90 mm
  • Heated lengths of 600 or 610 mm depending on the model
  • End zone control is via back to back thermocouples (TZF 15)
  • End zone control is via retransmission of set point (TZF 16, TZF 17 and TZF 18)
  • Carbolite 301 controller, with single ramp to set-point & process timer (TZF 15 & TZF 16)
  • Programmable 3216P1 controller (TZF 17 & TZF 18)
  • Overtemperature protection (TZF 17 & TZF 18)

Options:

  • Wide choice of tube diameters and materials is available: eg quartz, ceramic, metal
  • Over-temperature protection (recommended to protect valuable contents & for unattended operation) (TZF 15 & TZF 16)
  • Control module with 2 metre conduit to furnace
  • Insulation plugs & radiation shields to prevent heat loss & improve uniformity
  • Modified atmosphere and vacuum assemblies are available
  • A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
  • 'Retransmission of Setpoint' control configuration to facilitate programmed cooling (TZF 15)
