To reduce this problem, the crimping tool should be regularly checked to ensure that the cap
cannot turn once it is crimped, and that the under edge of the cap is flush with the vial lip. Also,
check that any obstacles do not hinder the turret and that the vial handlers at the end of the arm
are clean.
In that case we recommend to check:
• check the vial handlers are not broken;
• check the vial, septa and the crimp cap;
• check if the turret has had an unexplained collision with some object, and if vial handlers
or the vials are dirty.
• check the turret alignment, if not correct, contact your Supplier or the Technical
Assistance Centre.
