Sintering Furnace LT 02/13 CR for Cobalt-Chromium
LT 02/13 CR
Forced cooling system with compressed air
Flowmeter for Argon
The sintering furnace LT 02/13 CR is perfectly suited for sintering of cobalt-chromium restorations. The blanks are placed in a special sintering bell and will be heat-treated under argon. The specific design in combination with sintering pearls provides for good sintering results in a nearly oxygen-free atmosphere at very low argon consumption.
The system is open and can be programmed for various materials up to sintering temperatures of 1300 °C. Two pre-installed sample programs, which can be adjusted individually. Furthermore, the sintering furnace LT 02/13 CR is designed for a single-phase connection.
- Tmax 1300 °C

Sintering Bell for Sintering Furnace LT 02/13 CR
For sintering of NEM restorations under Argon, a sintering bell with very good sealing is used. The sintering bell is made of durable, low-wear SiC material. The material is placed in the sintering bell and sintered under argon. In total, up to 30 units per sintering process can be inserted. The specific design in combination with sintering pearls provides for good sintering results in a nearly oxygen-free atmosphere at a very low argon consumption.
Sintering Pearls for Sintering Furnace LT 02/13 CR
The use of sintering pearls which reduce the atmosphere inside the sintering bell ensures opitmal results. They prevent the crowns and bridges from sticking or jamming during the sintering process. It must be ensured that the frameworks und single crowns are imbedded in sintering pearls up to their upper edge. Though, it must be ensured that they should not enter the crowns in order not to hinder the sintering shrinkage.
Special Tongs for Charging the Sintering Bell
We offer a pair of special tongs for loading and unloading the furnace. The sintering bell can easily be removed from the sintering chamber. Note: The accessories described above are designed for cold charging and discharging. Removing them in hot condition is not permitted.
