1Pc Laboratory Alumina Corundum Crucible with Lid 5/10/20/25/30/50/100/150/200ml/300ml High-Temperature ResistantProduct Description:1. Product: Crucible (with lid)2. Material: Alumina3. Quantity: 1Pc4. Product Features:Alumina Ceramic Crucible Series: Suitable for analyzing various laboratory metal and non-metal samples and melting materials. Crucible Series—Meets laboratory and diverse industrial analysis requirements.Alumina Crucible/Alumina Ceramic Crucible Characteristics:1). 1). High Purity: Al₂O₃ > 99%, excellent corrosion resistance2). Superior Temperature Resistance: Long-term use up to 1600°C, short-term tolerance up to 1800°C3). Excellent Thermal Shock Resistance: Resistant to cracking4). High casting densityPrecautions:1. Slightly larger outer diameter of the lid compared to the crucible is normal.2. Minor color variations result primarily from different temperature zones during firing. Materials are identical; use with confidence.Precautions1. For initial use, bake the crucible in a 105°C oven for 120 minutes to remove moisture.2. Never use gasoline torches, acetylene torches, alcohol torches, or direct heating on corundum crucibles to prevent cracking from uneven heating.3. Avoid rapid temperature changes. Below 1200°C, temperature variation should not exceed 5°C/min; above 1200°C, variation should not exceed 10°C/min.Place of Origin: Mainland China
