To heat a number of round bottom flasks simultaneously (for extractions, distillations, and digestions) extraction mantle may be used. All extraction mantles are fitted with individual energy regulators with indicator light for each heating surface, allowing liquids with different boiling points to be heated alongside each other. The robust construction permits continuous operation of the units as required by routine extraction tests.

Advantages of Quartz Double Distillation Apparatus (Demountable )

• Compact design, with all contact parts made of  high quality, pure Electronic Grade transparent Quartz only.
• The main unit consist of a bottom Boiler and top Boiler with Condenser, which can be easily separated (Demountable ) for necessary cleaning or  maintenance, if required. Bottom vent provided in bottom Boiler for general cleaning and maintenance
• The main constituent of Quartz is SiO2 >99.9% which make the apparatus highly resistant to any thermal shock, devitrification and resistant to water and acids.
• The electrical heaters are so designed, they do not come into contact with water because they are embedded inside a Quartz tube, hence nullifying the possibility of metal contamination by the heaters.
• The given Volume of water in the Boiler during the distillation process is very Less, resulting in low heat loss, hence power is saved.
• The distillate obtained from this apparatus is PYROGEN FREE. It is also FREE from metal ions.
• All water connections can be given with threaded connectors
• Demountable ball Joint
• Spiral Heater has better life span that tubular sheathed heater.
