Dual-Zone High-Pressure Tube Furnace (2)

Laboratory Dual-Zone High-Pressure Tube Furnace

The HP1200 Dual-Zone High-Temperature High-Pressure Tube Furnace is equipped with a high-pressure solenoid valve, pressure sensor, and analog safety protection on the flanges. With up to triple safety protection, you can work with peace of mind. When the pressure inside the chamber exceeds the set value, the solenoid pressure release valve automatically opens to vent the gas, maintaining the pressure inside the tube at the desired level. This furnace can perform heat treatment on samples in high-pressure gas environments, with a maximum temperature of 1150°C. It is ideal for research on superconducting and dielectric materials.

Temperature and Pressure Allowance

The maximum allowable pressure varies with temperature, as shown below:

Furnace Temperature	Max Pressure in Chamber
0- 600°C	≤ 7MPa
600-800°C	≤ 6MPa
800- 900°C	≤ 3MPa
900- 1000°C	≤ 1MPa

(First heat up, then slowly introduce the gas; do not apply the required pressure all at once, as pressure will continue to increase with rising temperature.)

The high-temperature high-pressure tube is a consumable part; please replace it promptly if any deformation is observed.

Furnace Structure

1. Dual-layer openable structure for customers requiring rapid cooling, with an outer shell surface temperature below 60°C.

2. Interior coated with a nano high-temperature aluminum oxide layer to improve heating efficiency.

3. Openable design for easy loading and tube replacement.

Compatible Gases

and Crucibles

1. Supports oxidizing, protective, and inert gases, such as N2, Ar, and He.

2. To prevent sample contamination, it is recommended to wrap samples in gold or nickel foil and place them in an alumina or quartz boat before inserting them into the furnace tube. Avoid placing samples directly in the high-temperature high-pressure tube without a crucible.

Control System

1. The system can store up to 15 temperature curves, each with up to 30 “temperature-time” segments, eliminating the need to reset different experimental parameters.

2. Featuring a bilingual (Chinese-English) graphical interface, the 7-inch color touch screen offers intelligent control, real-time heating power display, and nonlinear temperature correction.

3. Safety functions include over-temperature and over-pressure alarms, thermocouple protection, leakage protection, and differential pressure release.

4. Triple safety protection:

First: Solenoid valve automatically releases pressure when it exceeds the set value.

Second: If exhaust is blocked or the solenoid valve fails, heating stops automatically upon reaching the system’s preset pressure limit.

Third: In case of sensor contamination or control failure, the analog pressure relay cuts power when pressure reaches the upper safety limit.

Heating Element

Mo-doped iron-chromium-aluminum alloy

Pressure Detection and Control

1. The high-pressure chamber is equipped with a pressure sensor connected to the control system for real-time display.

2. A high-pressure solenoid relief valve is mounted on the flange. When the pressure inside the furnace tube exceeds the set value, the solenoid valve will automatically release gas, keeping the chamber pressure within the preset range. The solenoid valve can handle a maximum automatic relief pressure of 15 MPa. When pressure exceeds 15 MPa, manual relief should be used instead of the solenoid valve.

2. Equipped with a 1/4 NPS internal thread interface on the furnace tube flange with high-pressure valves on both ends, and a pressure gauge on the right valve.

3. Optionally, a torque wrench can be purchased to avoid over-tightening the flange.
