Pot tongs |
| 1Please provide the Chinese content you would like translated. | 1. A common chemical instrument, typically used for holding crucibles. Generally made of stainless steel or hard, non-combustible, and non-oxidizable materials. 2. Use clean tongs. 3. When gripping 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 tongs tip upwards on the table or asbestos mat. 4. After the experiment is complete, clean the crucible tongs and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent section for holding crucibles; use the pointed end for other applications. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Special Note
Quality Assurance | One-year full machine warranty, excluding related consumables (mat boards and heating elements are excluded), lifetime on-site repair service available. |
Factory environment | 1. Indoor Use 2. Environmental temperature: ±5-45℃ range 3. The relative temperature of the surrounding environment shall not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the stove. |
Safety Protection | 1. When an electric furnace is first used or after a long period of disuse, it must be seasoned; otherwise, the furnace chamber is prone to cracking. 2. Keep clean regularly and check the electrical furnace wiring for good contact on a routine basis. 3. When using the electric furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour various flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, when heating up initially, the furnace is cold and requires a significant amount of heat absorption. |
After-sales service | 1. We commit to resolving any technical inquiries from our clients within 1 hour. 2. We promise to issue the test results for equipment returned for repair within 1 working day and complete the repair within 3 working days. Special materials require customization and will be handled accordingly. 3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendly Reminder | Do not operate the equipment at the rated temperature for extended periods 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 a heating rate and cooling rate of 10℃/min. Cooling rate should not exceed 5℃/min. 5. This furnace does not have a vacuum-sealed structure; therefore, it is not suitable for introducing flammable and explosive gases. 6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. These can be repaired using an alumina coating. |
