#28 diluent with dropper cap. This is used for 1000 doses of the Newcastle or Newcastle Bronchitis vaccines, to give individual doses of the vaccine by eye or nose drop method. The problem is that those vaccines no longer come in 1000 dose bottles. But, if you reduce the dry vaccine cake you use to 1000 doses worth before mixing with the diluent, then you can use the dropper method like we used to for individual birds.
MAKE SURE YOU DO NOT USE THE WHOLE 5,000 OR 10,000 DOSES OF DRY VACCINE CAKE IN ONE OF THESE BOTTLES OF DILUENT, IF YOU DO, YOU WILL OVERDOSE YOUR BIRDS AND MAKE THEM SICK!!!
