Silicon Molybdenum Rods | | 2Please provide the Chinese content to be translated. | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, forming a dense quartz glass film on the surface to prevent further oxidation. Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800℃, can be used as heating elements for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles | | 1Please provide the Chinese content that needs to be translated into American English. | A common chemical instrument, typically used for gripping crucibles. Generally made of stainless steel or hard, non-combustible, and non-oxidizable materials. 2. Use clean tongs. 3. When handling a hot crucible with tongs, preheat the tip of the tongs to prevent the crucible from cracking due to local cooling. After use, place the tip of the tongs upwards on the desk or a asbestos pad. 4. After the experiment, clean the crucible tongs thoroughly and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent section for holding crucibles, and the pointed end for other uses. 6. Crucible tongs are not necessarily used with crucibles; they can also be used independently. | |

Special Note
Quality Warranty | One-year warranty on the entire unit, excluding related consumables (mat boards and heating elements excluded).Lifetime On-Site Maintenance |
Factory environment | 1. Indoor use 2. Environmental temperature within ±5-45°C range. 3. The relative temperature of the surrounding environment should not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulate corrosive gases around the stove. |
Safety Protection | 1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to dry the furnace to prevent cracking of the furnace chamber. 2. Keep the oven clean and inspect the electrical connections regularly to ensure good contact. 3. During operation, the furnace temperature must not exceed the rated temperature to prevent damage to the heating elements. It is strictly prohibited to pour various flammable liquids and molten metals into the furnace. 4. During the working process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, at the beginning of the heating, the furnace is cold and requires a significant amount of heat to be absorbed. |
After-sales Service | 1. We commit to addressing any technical inquiries from customers within one hour. 2. We promise to provide a test result within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials on a case-by-case basis. 3. Within one week of returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultations. |
Friendly Reminder | Do not operate the equipment continuously at the rated temperature to ensure its normal service life. 2. Carefully count and verify the quantity of goods and accessories upon receipt to avoid any inconvenience caused by shortages or omissions. 3. To extend the lifespan of the instrument, we recommend that the heating and cooling rates not exceed 10℃/min. 4. The cooling rate should not exceed 5°C/min. 5. This furnace does not have a vacuum-sealed structure; therefore, it is not suitable for introducing flammable or explosive gases. 6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. These can be repaired using an alumina coating. |
