Large Hole Porcelain Desiccator Plates

Crafted from high-purity laboratory porcelain, each plate is finished with a brilliant white glaze on one side for rapid, residue-free cleaning and to prevent particulate shedding. Unlike small-perforation plates, this series features oversized 35 mm to 50 mm diameter holes alongside a central lift hole. These large openings allow deep-bottomed porcelain crucibles, weighing bottles, and narrow-necked flasks to sit lowered and nested securely within the plate, lowering their vertical center of gravity and eliminating the risk of tipping during chamber decompression.

Key Functional Benefits:

• Secure Nested Positioning: The large-capacity 35 mm and 50 mm holes allow wide-base crucibles to slide partially into the plate rather than resting on top, providing unmatched stability against tipping or sliding
• Exceptional Thermal Shock Resistance: Engineered with a remarkably low average coefficient of expansion (3.56 x 10 < sup>-5 from 20°C to 200°C), allowing hot crucibles straight from a muffle furnace to be transferred to the plate without structural fracturing
• High-Temperature Glaze Integrity: The brilliant white glaze shows zero softening or degradation at temperatures up to 1000°C, ensuring a clean, non-contaminating surface for analytical-grade workflows
• Universal Chemical Protection: Elite resistance to aggressive acids and alkalis guards your moisture-free environment from accidental reagent splashes or corrosive chemical vapors
