VIALS IDENTIFICATION
Vials related to different parameters can be distinguished by mean of a
letter printed on the vial (beside the Hanna logo) and the cap color:
64
• Preheat the Hanna Reactor C 9800 to 150 °C (302°F). For correct
use of the reactor follow Reactor Instruction Manual.
Use of the optional HI 740217 safety shield is strongly recommended.
Do not use an oven or microwave because leaking samples can
generate a corrosive and possibly explosive atmosphere.
• Remove the cap from a Reagent
Vial.
• Add exactly 5.0 mL of sample to
the vial, while keeping the vial at
a 45-degree angle.
• Add the content of one packet of Potassium Persulfate for
Phosphorus analysis. Replace the cap and shake gently the vial
until all the powder is
completely dissolved.
• Insert the vial into the reactor and
heat it for 30 minutes at 150°C.
• At the end of the digestion place the
vials carefully in the test tube rack and
allow to cool to room temperature.
Warning: as the vials are still hot, be
careful in handling them.
• Select the program number
corresponding to Total Phosphorus on
the secondary LCD by pressing
PROGRAM t and s.
• Remove the cap from the vial and
add exactly 2.0 mL of Sodium
Hydroxide (NaOH) Solution 1,54 N,
while keeping the vial at a 45-degree
angle.
