Carbolite EVT & EVZ Compact Vertical Split Tube Furnaces
These Carbolite EVT & EVZ Compact Vertical Split Tube Furnaces use free radiating wire elements embedded within the insulation of the furnace body.
The benefit of this design is its flexibility with the use of tube adapters the same furnace can be used with a variety of tube diameters.
The single zone EVT and 3-zone EVZ split tube furnaces comprise a furnace body which is hinged and split into two halves along its length. This makes exchange of work tubes easier and also enables the furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace difficult.
The 3-zone EVZ furnaces provide excellent uniformity resulting from division of the heated length into 3 zones with its own controller and thermocouple. This range of tube furnaces does not include an integral work tube which must be selected as an additional item. The work tube length is dependent on the application, for example, for use with modified atmosphere or vacuum.
The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination.
- Heated lengths, 3-zone 450 or 600 mm (EVZ)
- Accepts work tubes with outer diameters up to 60 mm
- Wire elements in high quality vacuum formed insulation ensure fast heat up, excellent temperature uniformity and short cool down times
- Furnace splits into two halves and accommodates tubes or samples fixed into a test rig
- Outer mesh guard ensures operator safety
Options (specify these at time of order)
- A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
- Over-temperature protection (recommended to protect valuable contents & for unattended operation)
- A range of additional work tubes, end seals and work tube packages is available for use with modified atmosphere and/or vacuum
- Vacuum packages with a choice of rotary vane pump or turbomolecular pump are available for furnaces with tube inner diameters of 60 mm and above
- Wide choice of tube diameters and materials is available: eg quartz, ceramic, metal
- Insulation plugs & radiation shields to prevent heat loss & improve uniformity
