Small Hole Porcelain Desiccator Plates

Crafted from high-grade laboratory porcelain, each plate is finished with a brilliant white glaze on one side to facilitate easy cleaning and prevent particulate shedding. The surface features numerous 5 mm diameter perforations alongside an oversized 25 mm center hole, allowing for efficient convective airflow and easy finger-lift retrieval during chamber maintenance. With exceptional chemical durability and resistance to extreme thermal transitions, these plates are an indispensable asset for analytical chemistry, gravimetric determination, and sample drying protocols.

Key Functional Benefits:

• Elite Thermal Shock Resistance: Engineered with a remarkably low average coefficient of expansion (3.56 x 10^-5 from 20°C to 200°C), allowing hot crucibles straight from the muffle furnace to be placed directly onto the plate without risking structural cracking
• High-Temperature Glaze Stability: The single-sided glazed surface remains perfectly stable with no softening or degradation occurring up to 1000°C, ensuring a non-contaminating interface for high-purity assays
• Universal Chemical Protection: Delivers excellent resistance against aggressive laboratory acids and alkalis, protecting your drying setup from accidental reagent spills
• Optimized Convective Perforations: Structured with a uniform grid of 5 mm small holes to maximize vertical moisture diffusion toward the underlying desiccant bed while preventing small vials from tipping
