1. Distillation Flask
Capacity            :    500mL
Type                  :    Side-arm type having the dimensions shown in Fig. 1 of ASTM D402.

2. Condenser
Type              :    Standard glass-jacketed,
Length          :    200 to 300 mm
Overall tube length    :    450 ± 10 mm

3. Electric heater with Digital Temperature controller
Electric heater with Microprocessor based AUTO-TUNE PID Digital temperature controller cum indicator with PT-100 Sensor.

4. Adopter
Heavy-wall (1-mm) glass, with reinforced top, having an angle of approximately 105°.  The inside diameter at the large end will be approximately 18 mm, and at the small end, not less than 5 mm. The lower surface of the adapter will  be on a smooth descending curve from the larger end to the smaller.
