Setting up for normal distillation

(Starting from the position for reflux
distillation)
For normal distillation the collection
flask has to point down. Slacken the
red locking knob (14), pull out the
fastening knob (13) and swivel the
condenser (with flask and support
rod) through 180° until the fastening
knob (13) latches in the second posi-
tion. Then re-tighten the red locking
knob (14).

Setting up for reflux distillation

(Starting from the position for normal
distillation)
For reflux distillation the condenser has to be in
upright position and a vacuum cap (0) is used
instead of the collection flask (L). To re-position
the condenser, loosen the locking knob (14),
pull out the fastening knob (13) and swivel the
condenser with flask and support rod through
180° until the fastening knob (13) latches home.
Then tighten the locking knob (14).
