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, in packs up to 100ml. 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.
