The Ferro-matic vaccinator is manufactured by Henke-Sass Wolfe of Germany. This company is known around the world for its manufacture of high quality medical and veterinary equipment.
The Ferro-matic is especially for use attached directly to the vial or remedy bottle.
* An air inlet system is incorporated to prevent vacuuming of the bottle. If remedy is in a pillow-pack (collapsing) bottle, where air admission is not desired, the optional No. 2 adaptor should be used.
