These pipettes hold 5 ml (one teaspoon) of water, ideal for properly diluting your drugs when using our fentanyl test strips. Alternative tools are a measuring teaspoon (like the ones for baking) or a standard plastic bottle cap from any 20 oz soda bottle (which holds just over a teaspoon of water when full).
Reusable, but only put clean water in the pipette or it may become contaminated with drug residue and influence the test results.
