To take a small sample of the liquid for testing, remove the plastic cap from the tip of the bottle (if present) and then use a small knife or screwdriver to remove the small central circular metal piece covering the rubber stopper (Fig 15B.1). This will expose the rubber seal. The needle of the hypodermic can then be pushed through the stopper into the bottle. Use the hypodermic 0.5ml syringe supplied with the Exit Nembutal Test Kit (or an equivalent). With the needle in place, invert the bottle and carefully withdraw the syringe plunger until there is 0.01ml of liquid in the syringe.
