1pcs Lab 5ml to 1000ml Cylindrical Corundum Crucible 99% Alumina Ash Crucible High Temperature Resistance 1600 Degrees(5ml)

Quantity: 1 PC/ManyProduct features:Corundum ceramic crucible series: suitable for various laboratory metal and non-metal sample analysis and molten materials. Crucible Series - Used for laboratory and various industrial analysesCharacteristics of alumina crucible and corundum ceramic crucible:1). High purity: Al2O3>99%, good chemical corrosion resistance2). Good temperature resistance, long-term use at 1600 ℃, short-term use at 1800 ℃3). Good cold and heat resistance, not easy to crack.4) High grouting density.precautions1. It is recommended to bake the crucible in an oven at around 105 ℃ for 120 minutes during the first use to remove moisture.2. The corundum crucible cannot be heated with gasoline spray gun, acetylene gun, alcohol spray gun or directly heated to avoid uneven heating and cracking of the crucible.3. The heating or cooling speed should not be too fast. For temperatures below 1200, the temperature change should be less than 5/min. For temperatures above 1200, the temperature change should be less than 4/min. It is recommended to turn on the power to control the temperature for cooling. At high temperatures, turning off the power in advance and using an electric furnace for cooling may cause the crucible to crack if the cooling rate is too fast.4. The distance between the crucible and the heating element (such as carbon tube, silicon molybdenum rod, or heating wire) should be greater than 5CM. It should not be used for carbon or iron related products.5. Avoid direct contact between the bottom of large crucibles (larger than 100mm) and the furnace bottom as much as possible. It is recommended to use a corundum pad and place the crucible on top of it (as shown in the figure below) to create air convection and extend the service life of the crucibleHighly concerned chemical substances: noneOrigin: Mainland ChinaCategory: Beaker
