1. PREPARATION Remove components from the box and place the 2
test tubes into the holder in the front of the box.
2. SAMPLE INTRODUCTION
dispensing cap from Tube #1. Work the plunger of the sampling syringe
a few times to ensure that it slides easily. Place the tip of the syringe
into the well-mixed oil sample to be tested and slowly pull back on the
plunger until it reaches the stop and cannot be pulled further, making
sure the sample contains no air bubbles. Remove the syringe from the
oil sample and wipe any excess oil from the outside of the syringe with
the enclosed tissue. Dispense the oil sample into Tube #1.
3. REACTION Replace the black dispensing cap on the test tube tightly.
Break the bottom (colorless, white-dot) ampule in the test tube by
squeezing the tube firmly once in the center of the ampule. Shake the
tube well for 15 seconds.
4. EXTRACTION Remove the caps from both test tubes and pour the
clear buffer solution from Tube #2 (white cap) into Tube #1 (black
dispensing cap). Replace the black cap tightly on Tube #1 and break
the top (blue-dot) ampule in Tube #1. Shake the mixture vigorously for
30 seconds. Vent the tube by partially unscrewing the dispensing cap
one half turn and re-tighten the cap securely. Stand the tube upside
down on its cap and allow the phases to separate for a full three
minutes.
