screw-cap vials.
Check that your vial is crimped as follows:
1. Cap has no metal folds or wrinkles on the part of the cap that wraps under
the neck of the vial.
• If there are folds or wrinkles, flatten any wrinkles by turning the vial
about 10° and crimping it again. Adjust the crimper for a looser crimp
by turning the adjusting screw clockwise.
2. Cap is too tight to turn by hand.
• If the cap is loose, adjust the crimper for a tighter crimp by turning the
adjusting screw counterclockwise. Crimp the cap again.
