Used in the microbiological laboratory for incubations, water baths maintain samples at a precise temperature from just above room temperature up to 990C. Here are some important things you should know while using water baths
- The bath should be filled with water before it is switched on.
- Set it at the right temperature; if the bath is being used for an experiment, check to see that the temperature is maintained.
- Use only water as the bath liquid and make sure there is not contamination by other liquids.
- Ensure that water is always fresh and well oxygenated; changing the water on a regular basis and emptying the bath when not in use for a long time checks contamination and corrosion.
- Using de-ionised water helps prevent corrosion; though the immersed parts are usually made of high quality steel, certain types of corrosion can cause damage.
- Micro-organisms can grow in water baths, affecting performance as well as posing a health risk. Using biocides can guard against biological infestation and growth.
- The water and surfaces can be hot during and after use. Empty the bath only after the water has come down to a safe level.
- Keep the equipment in a place where there are no dangerous chemical mixtures.
- If any hazardous material is spilt on the device, remove it from the power supply and perform a thorough technical inspection before using it again.
There are many types of water baths in the market. General purpose water baths are ideal for general lab applications and offer excellent performance. In shaking water baths, the speed of shaking can also be set and the shaking mechanism can be turned on or off. Shaking water baths featuring orbital and reciprocating shaking ensure reliability, consistency and quiet operation. Regardless of the type of water bath you choose, always read the instruction booklet before use.
