Reflux - Wikipedia

A mixture of reactants and solvent is placed in a suitable vessel, such as a round bottom flask.This vessel is connected to a water-cooled Liebig or Vigreux condenser, which is typically open to the atmosphere at the top.The reaction vessel is heated in order to boil the reaction mixture; vapours produced from the mixture are condensed by the condenser, and return to the vessel through gravity.

Compact—Save valuable bench space with the small footprint of our general purpose baths.; Effortless—Automatically preheat and turn off your bath for efficient work scheduling with new auto-on and auto-off timers. Intuitive—Simplify parameter setting and monitoring with new icon-based controller interface to help ensure safe operation.

- Division of Research Safety | Illinois

Cooling is mandatory if heat generated by the reaction exceeds the vessel's heat transfer ability. Always have a means to cool the reaction vessel if the reaction gets out of control, e.g., pull the heat source and cool in a water bath. Good temperature control (albeit addition rates or cooling) is key to preventing thermal runaways!

Stability Measurement – Preparing the reaction vessel .

Before the sample is weighed into the reaction vessel (6.1429.040, 6.1429.050), contamination, such as dust particles and small pieces of cardboard, must be removed. A sharp jet of nitrogen, for example, is suitable for this. This can be used to blow particles off both the internal and external surface of the reaction vessel.

Working Principle of Water Bath? - Lab Instrument Manufacturer

Water baths are used to heat those substances, which can't be heated directly on Bunsen burner or hot plate or any other media. However only those materials can be heated with water bath whose boiling point is less than that of water. The water bath is used in the lab to allow a chemical reaction .
