The Carbolite HZS-2G Gradient Tube Furnace is specifically design to provide a temperature gradient along the length of the heated zones.
They 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 two independent zone HZS-2G 12/425 split tube furnace comprises 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 2-zone HZS-2G furnace includes a 25 mm long unheated zone barrier between the two 200 mm heated zones. Each heated zone has its own temperature 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.
Note: The temperature gradient achievable is influenced by work tube diameter. Larger gradients will be achieved with smaller diameter work tubes because heat transfer between zones will be less.
