Injections labeled for veterinary use are exempt from packaging and storage needs check here regarding the limitation to single-dose containers plus the limitation on the amount of many-dose containers.
B: The constituted Answer is not really drastically much less crystal clear than an equivalent quantity on the diluent or of Purified Water contained in an identical vessel and examined equally.
