What do I do if the sample vial does not work?

Sometimes it happens that samples come under vacuum after filling, to fix this, after removing the protective cap, you can very carefully remove the top of the tube by removing the atomizing part of the tube. You can do this by holding the tube straight and pulling the nozzle at an angle. When air is added again, you can click the atomizer back on, after spraying again a few times, the sample will work again.
