Re-open the 2 liter container and insert the test strip of a spot test cassette into the liquid. Wait and read the result. A clear positive should be recorded. A clear positive is a single clear line at ‘C’ on the cassette, with no line forming at the ‘T’ level (see Fig 18.3).
Use a 3ml syringe attached to a 2ml micro-pipette to take exactly 2ml of liquid from this 2 liter container and add this to the second 2 liter distilled water container - label this bottle #2.
Reseal and again invert to mix thoroughly. Finally, use a new cassette to test bottle #2. Another positive should be recorded, although a faint line may now be noticed at ‘T’. A clear ‘C’ confirms that the test sample has a purity of better than 70%.
Note: To test veterinary Nembutal liquid, use a syringe with a 25G needle. Remove exactly 3ml of the sample and add this directly into the first distilled water bottle - proceed as above.

Max Bromson Quantitative Test Results
Home purity testing requires care and the results obtained can sometimes be difficult to interpret. The benefit of the Max Bromson Triple Test is that it enables three tests to be carried out.
A spurious or unexplained result from one test can then reasonably be disregarded if the other two tests return an adequate result.
