  Standard accessories





High temperature gloves


one double

It has good comfort and can keep hands warm; it is resistant to cutting, wear and heat (it can resist contact heat at 350 ℃ for 60 seconds, and 100 ℃ for 180 seconds) for long-lasting durability.


Heating element

Silicon carbide


two branch

Silicon carbon components and use temperature is high, hard and brittle, used after molding, such as silicon carbide made of silicon carbide rod, silicon carbon tube heating temperature can reach one thousand and five hundred The operating temperature is 1000-1200 ℃ in vacuum and 1350 ℃ in nitrogen atmosphere

Silicon molybdenum rod


two branch

When heated to high temperature in oxidizing atmosphere, a dense quartz glass film is formed on the surface of the rod to protect it from oxidation. Therefore, Si Mo rod has high temperature oxidation resistance. In the oxidation atmosphere, the temperature can reach one thousand and eight hundred It can be used as heating element of high temperature furnace for electronics, ceramics, magnetic materials, glass, metallurgy, refractory, etc.

Crucible tongs


one hold

1. A common chemical instrument. It is usually used to clamp the crucible. It is generally made of stainless steel, or nonflammable and refractory hard materials.

2. Clean crucible tongs are required.

3. When taking out the hot crucible with crucible tongs, it is necessary to preheat the tongs first, so as to prevent the crucible from cracking due to local cooling. After use, the tongs should be placed upward on the table top or asbestos net.

4. After the experiment, the crucible tongs should be wiped clean, put into the experimental equipment cabinet, and placed dry.

5. The bending part is used for holding the crucible, and the tip is used for other purposes.

6. Crucible tongs may not be used together with crucible, but can also be used alone
