Proper handling of chemical test equipment

This test equipment is designed to provide years of dependable service.
Following these suggestions will help increase equipment performance:

1. Carefully follow all instructions.
2. Do not handle tablets; dispense from cap to test tube.
3. Carefully wash and rinse all apparatus used.
4. Tighten reagent caps immediately after use. Do not interchange caps.
5. Avoid prolonged exposure to direct sunlight.
6. Avoid temperature extremes.
7. Anticipate your requirements for replacement reagents.
8. Keep all reagent containers out of reach of young children.
9. Reagents marked with an * are considered potential health hazards.
Read MSDS at www.lamotte.com before use.

The accompanying Garden Guide Manual provides:

1. Instructions on the proper collection and preparation of soil samples.
2. Essential information for interpretation of test results.
3. Lime and fertilizer recommendations.
4. A soil test record form.

When matching a test color to a color chart, stand with
the light source behind the observer and hold the test
tube approximately one-half inch away from the color
chart. If the color of a test reaction falls between two
standard colors on a color chart, the mid-point between
the two standard values is taken as the test result. For
example, a pH test color reaction falling between the
standard colors for pH 4.0 and pH 5.0 represents a test
result of pH 4.5. In the other tests color reactions may
either match, fall between, or fall beyond the three
standard colors representing “Low,” Medium,” and
“High.” Therefore seven different test results are
possible: Very Low, Low, Medium Low, Medium,
Medium High, High, and Very High.
