Description

Porcelain Desiccator Plate with Large Holes

The plates feature a large central hole, along with 6 to 10 additional perforations depending on the plate size, and are glazed on one side.
For thermal shock resistance, the average coefficient of expansion from 20°C to 200°C is 3.56 x 10⁻⁵, increasing to 4.69 x 10⁻⁵ at 1050°C. Every batch of porcelain undergoes heat testing at the factory. The glaze remains stable and doesn’t soften up to 1000°C, maintaining an extremely white appearance. In terms of chemical resistance, the plates perform excellently against acids and alkalis, with the exception of hydrofluoric acid.
