Airflux condenser apparatus

        
 

Efficient aluminum heat sink disperses heat. Remove plastic cap on heat sink to fill with distilled water. Water passes through to glass condenser. Complete apparatus includes Airflux aluminum heat sink, removable glass condenser, and boiling flask.
  • Use with flasks up to 250mL size and heating mantles with 60W max. output
  • Condensers can be mounted in tandem* for flasks sizes up to 1L and 300W heating mantles with a controller for steady reflux rate
  • Mounts to 1/2in. lattice-rods or support stands via built-in clamp on heat sink

*Note: Do not use tandem mounted water-cooled Airflux units to condense solvents boiling over 100°C. The lower unit works at a temperature close to the boiling point of the solvent at high reflux rates. Alternative coolants such as ethylene glycol may be suitable. Tests should be carried out to determine satisfactory performance.

Coiled reflux condensers



The coiled reflux condenser circulates coolant through the coil. The jacketed version provides additional cooling capacity by allowing vapors to condense on the inner wall of the jacket.
