Dishes(Crystallizing with Spout)

A Crystallizing Dish with Spout is a shallow laboratory vessel designed for the controlled crystallization and evaporation of solutions, featuring a small pouring spout integrated into the rim. This spout facilitates easy and precise pouring of liquids or transfer of solutions without spills, making it especially useful during sample handling or solution transfer steps. The dish typically has a wide diameter with low walls, maximizing surface area for efficient evaporation and crystal formation. The presence of a spout adds convenience when decanting supernatants or removing liquid phases after crystallization. These dishes are commonly made from porcelain or borosilicate glass, materials that offer chemical inertness, thermal stability, and durability under lab conditions. The spout is smoothly formed as part of the rim to maintain ease of cleaning and prevent damage.
