Which domestic sealing machine is good

　　1、 Main features

1Four station sealing systemMainly used for oxygen free and anhydrous vacuum sealed storage of samples and high-temperature solid-phase synthesis, the entire system consists of a vacuum sealing machine, a hydrogen oxygen machine, a molecular pump system, a quartz tube, connecting joints, etc. Standardized customized quartz tubes and quartz columns ensure accurate matching of other specially designed tube joints, thereby further improving the sealing performance of quartz tubes and achieving higher standards of vacuum sealing.

2. The quartz tube sealing machine is designed as a vertical structure, with the quartz tube fixed vertically and the upper end fixed by dynamic sealing. The upper end fixing device and the lower end supporting device are designed as linked shafts, and can rotate synchronously up and down. And the lower support mechanism can be adjusted up and down according to actual needs. The bottom of the support platform is arc-shaped and can be attached to the bottom of the quartz tube. The quartz tube is sealed at one end. The rotating platform under the equipment is equipped with four heating devices, which can be used to heat the sample before sealing the tube.

3. The insulation material is high-purity alumina fiber with good insulation performance. The heating wire is placed inside the insulation material, and is formed by overall adsorption. It has a beautiful appearance and is energy-saving and environmentally friendly.

4. There is an insulation device above the heating furnace, which fits the diameter of the quartz tube to reduce temperature fluctuations inside the heating jacket.

5. The heating device is a lifting structure, and after heating is completed, the heating device can automatically descend, making it convenient to use a hydrogen oxygen flame to seal the quartz tube.

　　2、 Product advantages

1. High temperature fusion of quartz tube wall and built-in quartz column;

2. Automatic rotation of the dynamic seal, simple operation, and uniform heating;

3. Install a filtering device (sintered copper gasket, easy to replace) in the vacuum system to avoid drawing powder materials into the vacuum system;

4. High vacuum tube joint connection, with good sealing and high vacuum degree;

5. Compact structure, precise design, small size, easy operation;

7. Easy to operate, ready to learn and use, safe and reliable.
