It’s possible, but the amount of substance that remains in the vial is clearly not much.I'm not sure I understand it correctly, but in the vials I have tried so far, the thickness is not uniform, there is a gap in the middle like a canyon. You can see the needle there, and I usually pull it back almost to the opening to get the last drops out. Maybe the products you use come in different vials and don't have the canyon.
