To adjust or replace the nebulizer needle
Nebulizer Adjustment Fixture User Guide 9
7 If you need to replace the needle:
a Loosen the needle holder and pull it out of the nebulizer body. Dispose of
the used needle properly.
b Rinse the inside of the nebulizer body with water and an organic solvent
(methanol is preferred) to remove any contamination inside the
nebulizer body.
c Thread the new needle holder into the nebulizer body.
d While holding the adjustment fixture in a vertical position, install the
new
ferrule in the needle holder. The wider end goes into the needle
holder .
e Carefully remove the new needle from the shipping tube and adhesive
strip. Identify the sharp end of the needle.

Do not bend the needle as you slide it into the ferrule. The needle is fragile. A bent
needle results in poor alignment with the nebulizer body.
f Carefully slide the sharp end of the needle through the ferrule until 1 cm
of the needle remains at the ferrule.
g Push the needle into the ferrule until the needle is slightly visible flush
with the ferrule.
