PREPARE SAMPLE
Prepare sample for testing using Mini Dilution Kit
II #487202.
1. Rinse 50mL graduated conical tube with
distilled or deionized (salt-free) water.
2. Rinse the 3.0mL syringe with saltwater sample
to be tested. Finally, fill the 3.0mL syringe to the
2.0mL line very precisely (plunger ring should
line up at the 2.0mL line and little or no air
bubble should be present).
3. Add the syringe content (2.0mL salt water
sample) to a clean 50mL graduated conical
tube by pushing plunger all the way down to
expel sample.
4. Now, fill the graduated conical tube to the 40mL
line with distilled or deionized (salt-free) water.
Cap graduated conical tube.
5. Mix content of graduated conical tube by turning
up side down at least three times. 1:20 Dilution
Sample is ready for testing.
