The vertical split tube furnace range VST (single zone) and TVS (three zone) uses 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. These 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. This design is particularly suitable for incorporation into extension test and creep test apparatus.

• Maximum operating temperature 1200 °C
• Carbolite Gero 301 controller, with single ramp to set-point & process timer
• Accepts worktubes with outer diameters up to 110 mm
• Vertical furnace with a separate control module on a 2 m conduit
• Wire elements in high quality vacuum formed insulation ensure fast heat up, excellent temperature uniformity and short cool down times
• Supplied in 'near-hinge' configuration complete with stand

Insulating end vestibules improve chamber uniformity and incorporate interchangeable tube adapters. Carbolite hinged tube furnaces are designed for bench mounting, and are interconnected to a separate control cabinet with a 6 foot cable. Positive break furnace safety switch isolates power to the heating elements when furnace is opened. Standard vertical hinged tube furnaces are provided with a vertical support stand.

Heated lengths: Single zone 200, 300, 400, 450, 600 or 900 mm (VST); 3-zone 600 or 900 mm (TVS)
End zone: Control is via back to back thermocouples (VST) or end zones of 150 mm each end (TVS)
