If a number of lyophilized vials are to be reconstituted, a multiadd metering device to deliver the diluent will increase the efficiency of reconstitution. The key part of the sterile set is a three way valve and syringe used for metering the diluent.

Pictured above is the multiadd set and bag of sterile water for injection.
