High-temperature gloves |
| 1Double | High comfort and keeps hands warm; cut-resistant, wear-resistant, and heat-resistant (can withstand 350°C, can touch heat for 60 seconds, can touch heat for 180 seconds at 100°C) - durable and long-lasting. | |
Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with high usage temperatures, are hard and brittle. After molding, they are used, such as silicon carbide rods and tubes, which can reach high heating temperatures under air-dry conditions.1500100-120°C, for use under 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, 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°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 to hold crucibles. Generally made of stainless steel or hard, non-combustible, and difficult-to-oxidize 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 with the tip facing up on the table or a asbestos mat. 4. After the experiment, clean the crucible tongs and place them in the lab equipment cabinet for drying storage. 5. Use the bent portion for holding crucibles; for other uses, employ the pointed tip. 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 (mats and heating elements excluded).Lifetime On-Site Maintenance |
Factory environment | 1. Indoor use 2. Environmental temperature is within ±5-45°C range. 3. The relative humidity of the surrounding environment shall not exceed 85%. 4. No conductive dust, explosive gases, or gases capable of severely damaging metals and insulating materials are present around the stove. |
Safety Protection | 1. When initially using or reusing an electric furnace after a long period of disuse, the kiln must be seasoned; otherwise, the furnace chamber is prone to cracking. 2. Keep clean regularly and check the electrical furnace wiring for good contact periodically. 3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. Prohibition of pouring any 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 addressing any technical inquiries from our clients within 1 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 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 under-delivery or missing items. 3. To extend the service life of the instrument, we recommend that the warming 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 some time 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. |
