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 or a standard plastic bottle cap from any 20 oz soda bottle, which holds just over a teaspoon of water when full.

Reusable. Only use with clean water. Contaminating the pipette with drug residue will influence your test results.
