49-Well Alumina Microreaction Plate | Multi-Compartment Ceramic Titration Plate

This 49-Well Alumina Microreaction Plate is made from high-purity Al₂O₃ (>99%) using a precision slip-casting process to ensure high density and smooth, uniform surfaces inside and out. It offers excellent resistance to high temperatures and chemical corrosion, making it ideal for multi-sample reactions, titration experiments, or high-temperature laboratory applications.
Designed for continuous use at temperatures up to 1600°C, it can also be customized to meet specific laboratory or industrial requirements.

Precautions for Using 99% Alumina Crucibles

1. Pre-drying: Before first use, place the crucible or plate in an oven at approximately 105°C for 120 minutes to remove moisture.

2. Avoid direct flame: Do not heat directly with gasoline, acetylene, or alcohol torches to prevent cracking from uneven heating.

3. Maintain distance: Keep at least 2 cm between the crucible and heating elements (carbon tubes, silicon carbide rods, heating wires, etc.).

4. Controlled temperature change:

   • Below 1200°C: heating/cooling rate ≤5°C per minute

   • Above 1200°C: heating/cooling rate ≤4°C per minute

   • Use controlled power cooling to avoid thermal shock.

5. Support placement: For large crucibles, avoid direct contact with the furnace floor. Use corundum or other heat-resistant plates to elevate the crucible, promote air circulation, and extend its lifespan.
