Economical Constant Temperature Water Baths offer superior temperature control, range, and uniformity. Bath fluids can be controlled at temperatures as high as 100°C (60°C without cover) with 0.1°C precision and +/- 0.2°C uniformity.
What is constant temperature bath?
Constant Temperature Bath is used in hydrometer testing of soils to maintain sample temperatures at a uniform 68°F (20°C) ±. 05°C through gentle and thorough circulation. ... It is equipped with an over-temperature safety cutoff mechanism.
Why is it recommended to maintain a constant temperature of constant heat supply from the water bath?
Temperature control water baths are necessary when heating samples that cannot be exposed to open flames, such as certain flammable chemicals and cell lines. Water baths are susceptible to contamination so washing regularly and adding an antimicrobial formula to the bath is important.
Why is water bath used instead of direct heating?
Water baths are ideal for keeping reaction vessels at a constant, relatively low temperature (below 100 °C obviously), and also for ensuring an even distribution of heat.
