An orifice reducer allows you precise dispensing of essential oil without waste. O-Presto makes it easy to replace orifice reducers in sample vials.
Features: 2 slots—shallow for ¼ dram vials; deep for ⅝ dram vials.
Directions: Fill a sample vial with oil, leaving room for the orifice reducer at the top. Lift the pressure bar. Place the sample vial in the appropriate slot. Set an orifice reducer on top of the vial. Press down on the bar to push the orifice reducer into the bottle. Screw the cap onto the bottle. It's that easy!
