- Graphite tube for low-temperature use (700 - 1200°C): Outer diameter is 10mm, inner diameter is 8mm, length is 100mm, and the effective calcination cavity volume is 3.5mL. - Graphite tube for medium-temperature use (700 - 1600°C): Outer diameter is 8mm, inner diameter is 6mm, length is 100mm, and the effective calcination volume is 2mL. - Graphite tube for high-temperature use (700 - 2200°C): Outer diameter is 5mm, inner diameter is 3mm, length is 70mm, and the effective calcination cavity volume is 0.3mL.
(5) Temperature Control Accuracy: ±1°C. (6) Output Voltage and Current of DC Power Supply: Maximum voltage is 12V; maximum current is 250A. ### II. Working Principle and Characteristics A high-power DC power supply is used to convert 220V AC into 12V DC (with high current). The DC power supply supplies electricity to the graphite tube. The material is added into the graphite tube. After the graphite tube is energized with a large current, it heats up rapidly, quickly heating the material inside the graphite tube. An infrared thermometer is used to detect the temperature of the graphite tube and transmit the detection signal to the temperature controller. The temperature controller adjusts the output voltage according to the detected temperature of the graphite tube to maintain the temperature of the graphite tube at the required level. It can rapidly heat up to 2200°C within 25 seconds. It can be maintained at below 1600°C for at least 30 minutes and at 1600 - 2200°C for at least 300 seconds.
