This appears to be a standard laboratory-grade rectangular water bath designed for precise temperature control in experiments involving incubation, heating, or evaporation of samples. It’s commonly used in chemistry, biology, and material testing labs for maintaining stable water temperatures around beakers or flasks placed in the holes on the lid. The design emphasizes durability, insulation for energy efficiency, and ease of use with concentric rings to accommodate various vessel sizes.

Note:-Size should be difference and as per order
