Distillation is a process in many laboratories for the purpose of
separating and/or purifying components of a liquid mixture. The distillation apparatus used consists of
three major parts: <span>distillation flask - to heat the mixture and volatilize the components,
a condenser to cool the vapors back to liquid state, and a collection vessel. The apparatus is typically made of glass and
therefore subject to breakage.</span> <span>All components of the distillation apparatus
should be protected to a stable stand or rack to avoid it from falling over.</span>
