O-Presto Tool to Put Orifice Reducers in Sample Vials (1/4 and 5/8 dram)

In stock

The O-Presto makes inserting orifice reducers back into your oil vials easy!

An orifice reducer is wonderful because it allows you to measure out precise amounts of essential oil without waste. But it can be difficult to insert the orifice reducer when filling or refilling your oil vials. O-Presto makes it easy! And it works with our ¼ and ⅝ dram vials.

Instructions: Fill a ¼ or ⅝dram 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 (shallow slot for ¼ dram vials; deep slot for ⅝ dram vials). 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, and you're finished!
