Personally use the single ampoule, first one has then always what plug if you need fast times (z. B. as a rinse for foreign body in the eye) was there on the road, always at work, or .... and secondly, they are by the individual packaging fresh and you do not worry has to do, whether they are still usable. The individual vials can be used 24 hours after opening, mostly they are then already consumed. For larger packages (dropper bottle 5ml) you always have to pay attention to the date you opened (more than 6 weeks).
Can the product fully recommend, particularly the above mentioned reasons the Eizelampullen.
