Standard Accessories
Name | Image | Quantity | Description | |
High-Temperature Gloves |
| 1Double | Comfortable and keeps hands warm; cut-resistant, wear-resistant, and heat-resistant (can withstand up to 350°C, contact heat for 60 seconds, 100°C contact heat for 180 seconds) - durable and long-lasting. | |
Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with high-temperature usage and hardness, are brittle and are used after molding. For example, silicon carbide rods and tubes, when used in air-dry conditions, can reach high-heat temperatures.1500100-120°C, for vacuum conditions; 1000-1200°C under nitrogen atmosphere; long-term use temperature 1350°C |
Silicon Molybdenum Rod |
| 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface to protect them from further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800°C, can be used as heating elements for industrial high-temperature furnaces in electronics, ceramics, magnetic materials, glass, metallurgy, refractory materials, etc. | |
Pot tongs |
| 1Please provide the Chinese content to be translated. | A common chemical instrument, typically used for holding crucibles. Generally made of stainless steel or hard, non-flammable, and non-oxidizable materials. 2. Use clean tongs. 3. When handling a hot crucible with tongs, preheat the tips to prevent the crucible from cracking due to localized cooling. After use, place the tongs with the tips facing up on the table or a fiber glass mat. 4. After the experiment, clean the crucible tongs and place them in the lab equipment cabinet for drying. 5. Use the bent portion for holding crucibles; for other uses, the pointed tip is suitable. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used alone. | |

Special Note
Quality Warranty | One-year full machine warranty, excluding related consumables (mat boards and heating elements excluded), lifetime on-site repair service available. |
Factory environment | 1. Indoor use 2. Ambient temperature range: ±5 to 45°C 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or gases capable of severely damaging metals and causing insulation corrosion are present 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 clean regularly and check the electrical furnace wiring for good contact on a schedule. 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 and molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300°C, and the heating rate should be moderate. This is because when heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |

Friendly Reminder | Do not operate the equipment for extended periods 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 service life of the instrument, we recommend a heating rate and cooling rate of 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 some use, the furnace may develop minor cracks, which is a normal occurrence and does not affect its operation. It can be repaired with an alumina coating. |
