For Injections in cartridges or prefilled syringes, assemble the container with any needed equipment like a needle or plunger. Subsequent the same course of action as earlier mentioned, and with no emptying the needle, transfer the complete contents of each and every container into a dry, tared beaker by slowly but surely and consistently depressing the plunger.

 CSEs became an accepted source for planning of ordinary curve calibrators and as assay controls, and have supplied a value preserving to LAL consumers and assisted to protect the stock of primary criteria.  FDA encourages the continued use of CSEs which are suitably calibrated into the Intercontinental reference endotoxins common.
