As filling of adhesive and as a dropper of fats and oils

When handling liquid containing volatile oil or solvent content, I tried using glass as a trial because it will be damaged by resin several times. This tip shape is safe because it is difficult to remove the tube because it can be inserted long. Sliding resistance of the piston is very small unlike resin syringe, so it is easy to come off if it gets out of oil, so just be careful about that point.
