Dry powder, wet-chemical and dry-chemical fire extinguishers working functions have to be explained. Concept Introduction: Solvents are used for many chemical reactions , in which traces of water or oxygen would in contamination and unsuccessful synthesis. The organic solvent is heated to boiling its vapour rise up the glassware and is condensed back to its liquid state using a water filled condenser. The repeated process of heating a solvent to boiling and condensing its vapour is known as reflux. The moisture/air-free solvent is collected in the receiver flask, which may be removed for use via syringe. A nitrogen bubbler system is used to flush the solvent still with an inert gas to prevent moisture and oxygen from dissolving in the solvent, and prevent a build-up of pressure that would result in a dangerous explosion.
