Important Properties of CoorsTek

• Chemical-Porcelain Ware
• Thermal-Shock Resistance
• Average coefficient of expansion from 20° C to 200° C is 3.56 x 10-6, gradually increasing to 4.69 x 10-6 at 1000° C
• Experience has indicated suitability of particular shapes for specific uses
• It remains the responsibility of the user to determine the suitability for his or her use
• To prevent thermal stress cracks on porcelain ware, CoorsTek strongly recommends a heating/cooling rate not to exceed 200° C/hour
• High-alumina labware temperature change rate should not exceed 150° C/hour

Prolonging Labware Life

• Follow gradual heating and cooling rates.
• Use an oven or hot plate as an intermediate step when quicker heating/cooling rates are required.
• Gradually increase flame intensity when using a gas burner.
• Avoid contact of heated ware with a cold surface.
• Carefully inspect your labware prior to each use.
• Do not use any product that appears defective.
