How to Heat Large Masses

Industrial and academic institutions use various pieces of heating equipment (steam baths, oil baths, heating mantles, Bunsen burners, sand baths, hot water baths), depending on the specific materials being heated and the specific reactions taking place. When heating large masses, steam baths are the best option. Steam baths, which are often used to heat solutions to about 100 degrees Celsius, come in a variety of sizes and have concentric rings as covers, which you can add or remove to "control" the size of the bath. Moreover, steam baths, which are supplied by a central steam boiler, eliminate any potential fire hazards.

Instructions

- 1
  Find the two inlets on the steam bath. One of them is designated "steam in," and the other is designated "steam out." Specific designations may vary, depending on the manufacturer. Connect both inlets to flexible laboratory plastic tubing.
- 2
  Connect the plastic tubing on the "steam in" inlet to a steam source in your laboratory. Place the "steam out" plastic tubing so that condensed water from the bath can easily flow out of the tubing into a nearby sink.
- 3
  Place your substance to be heated in an appropriately sized beaker, on top of the steam bath. For more efficient heating, you can remove some of the inner concentric rings of the bath, and immerse your beaker in the actual bath.
- 4
  Turn on the steam source. Place a thermometer inside the beaker of the substance that you are heating, and heat your substance until it reaches the desired temperature.
