A typical serological water bath features a double-walled construction with an inner stainless steel chamber, an outer mild steel powder-coated chamber, and insulation between them to prevent thermal loss. Key specifications include a temperature range from ambient to 100°C with an accuracy of ±0.5°C to ±1°C, precise PID or thermostatic control, a gabled or flat stainless steel lid to reduce evaporation, and a safety system with a low water level cutoff. Stirring mechanisms and a drain plug are also common features for uniform temperature and easy cleaning, respectively.
