Desiccator plates are used in vacuum drying and degassing procedures. The perforated plates are noncombustible even at maximum vacuum. Glazed on one side, plates will not soften. With a strong chemical resistance, ceramic-porcelain models work with the difficult reagents. Also temperature resistant, the reusable desiccator plates can be autoclaved to sterilize. The center hole allowing easy placement and removal from apparatuses may vary in diameter size. Styles may have numbered quadrants for easier sample location.
