A water bath instrument is an essential laboratory device used to heat samples gently and uniformly at a predetermined temperature. It is especially useful for experiments and procedures that require controlled heating without exposing samples to direct heat sources.
Due to its accuracy and safety, water baths are commonly found in clinical laboratories, pharmaceutical units, research institutions, biotechnology labs, and academic colleges.
Principle of Water Bath Operation
The working principle of a water bath is based on indirect heating. Water inside the chamber is heated using an internal heating element. When laboratory vessels are placed in the water, heat is transferred evenly, ensuring stable temperature conditions throughout the process.
This method helps maintain sample integrity and prevents sudden temperature fluctuations.
Different Variants of Water Baths
• Laboratory Water Bath
Used for general heating purposes.
• Digital Temperature Water Bath
Offers precise temperature control and digital readout.
• Serological Water Bath
Designed for blood serum and clinical testing.
• Constant Temperature Water Bath
Maintains a steady temperature for prolonged experiments.
• Shaking Water Bath
Provides heating with continuous agitation.
