Hot plates are conceptually simple a flat surface with heating elements–They do not produce open flames and are well suited for oil or sand bath useBut there are key considerations on the proper choice of hot plates and important safety factors that users should be aware of.
IKA heating baths the best choice when it comes to heating and tempering in the labIKA heating baths shine due to their stellar safety characteristicsAll baths are equipped with a double jacket for protection against burns and a safety temperature monitor to keep the bath from over heating.
If you have previous experience using a Variac with heating mantles the settings will not translate to the oil bath as oil bath wires heat more rapidly than a heating mantles wiresA paper clip can also be used in an oil bath Figure 1.
Jan 04 2015 To address this heating under reflux is usedThis refers to heating a solution with an attached condenser to prevent reagents from escapingAs seen above any vapor will condense on the cool surface of the attached condenser and flow back into the flaskThe hot water bath pictured is an optional component of heating under reflux and is.
Jul 01 2014 heating mantle oil bath or hot plateRecently a new technique has come to the forefront of chemical research microwave dielectric heatingIn a similar way to the introduction of the heating mantle this technology will no doubt require a change in the chemist’s mindset.
