  2. Cooling bath - Wikipedia

    en.wikipedia.org/wiki/Cooling_bath

    A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation , to remove solvents using a rotary evaporator , or to perform a chemical reaction below room temperature ...

    A laboratory bath could refer to any of the following: Cooling bath: a laboratory device that lowers the temperature of the bath or improves heat conduction; Heated bath: a laboratory device that raises the temperature of the bath to enhance a chemical reaction; Laboratory water bath: a laboratory device that maintains the temperature of the bath

  5. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a vacuum pump. [2] Liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in an insulating layer of ...

  6. Frigorific mixture - Wikipedia

    en.wikipedia.org/wiki/Frigorific_mixture

    A frigorific mixture may be used to obtain a liquid medium that has a reproducible temperature below ambient temperature. Such mixtures were used to calibrate thermometers. In chemistry a cooling bath may be used to control the temperature of a strongly exothermic reaction. A frigorific mixture may be used as an alternative to mechanical ...

    This chilling towel is made from high-quality Polyvinyl Alcohol (PVA) which absorbs water really well. Once absorbed, the water slowly evaporates to keep you for long stretches.

  8. Cloud point - Wikipedia

    en.wikipedia.org/wiki/Cloud_point

    The entire test subject is then placed in a constant temperature cooling bath on top of a gasket to prevent excessive cooling. At every 1 °C, the sample is taken out and inspected for cloud then quickly replaced. Successively lower temperature cooling baths may be used depending on the cloud point.
