  1. You can transfer oil from another bottle by using a plastic syringe or glass dropper. After the oil is in the bottle, place the orifice reducer in the hole and press until fully inserted.
  2. Better yet, our 45-drop pipette works extremely well for filling (and refilling) these sample vials because the tip can fit through the orifice reducer, allowing you to put oil in after inserting the orifice reducer. This reduces mess and waste.
  3. Once the oil is in and the cap is on your samples, you may want to place rectangle labels on the vials. For professional-looking samples along with information cards, you can purchase our Premium Sample Card and Label Set.
