Product Description:

Some situation, porcelain cuple cannot reach the requirement of user to use it in high temperature, but use the 95% Alumina Ceramic Cuple can solve the problem.

Storage .
1. The Alumina Ceramic Cuple for Laboratory Analysis shall be kept in a dry, gentle and ventilated place. Because the crucible is hygroscopic, it will absorb moisture from the air and from the humid ground. If the storage is under unfavorable conditions of humidity or foggy, high humidity, it is recommended that the crucible be drained of moisture before installation.

2. The Alumina Ceramic Cuple should always be placed on the pallet, not directly on the cement floor, crushed stone floor or soil floor, if the wet crucible is violently heated or comes into contact with the molten floor, it may cause cracking or violent reflection.
