Instructions
1. Using #0530 test paper, swipe surface or object to be tested, or place suspected substance on paper; or may be used without test paper (spray directly on surface/object)
2. Testing must use three DropEx bottles in sequence beginning with DropEx 1, then DropEx 2, and then DropEx 3. Using a new test paper, testing may resume with PDK Bottle A and, if no reaction, testing with PDK Bottle B+ (Bottle A must be used first). Testing stops when a positive color reaction occurs.
3. Remove cap: turn bottle upside down and squeeze bottle to release drop of liquid on test paper or surface. Additional drops can be used if results are not certain.
4. Repeat with each bottle until a positive color reaction occurs or until all bottles have been used.
5. Wait few seconds for possible color reaction: see color chart.
6. Use color chart provided to determine if color reaction is positive
7. If there is any doubt about a color reaction, throw it away and retest
8. If no color reaction within 5 seconds, the test is negative
9. A color reaction may be as small as a speck or much larger if large quantity is being tested
