The Avi-Jector pneumatic vaccinator is now available with a double injection system for simultaneously injecting day-old chicks with oil and water based vaccines. This vaccination equipment decreases labor, time and bird stress since the vaccination is done in one quick process.

There is a wives΄ tale that oil and water based vaccines can never be mixed. The Double Injection Avi-Jector puts the vaccines in contact for a fraction of a second and then absorption into the chick body begins. It is less stressful for the birds than a two-needle system and laboratory and field tests prove that the double injection does not lessen the effectiveness of the vaccines.

The double injection system is composed of two dosage calibrators and one injection system with a needle. The system can be installed in existing Avi-Jector vaccinators.
