HSW ECO MATIC® TWIN 

Dear Ben, thanks a lot for your comment. Could you please contact us under info@henkesasswolf.de with some further details on your findings? We at HSW are always very thankful for constructive feedback from the field and will try our best to help you make the Eco-Matic® Twin syringe work with the iron product of your choice. Some advice in advance: In general, iron products tend to be very sticky, especially once in contact with air. Dried iron product on a veterinary applicator may cause blocked valves and a sluggish operation. Therefore, it is very critical and important to clean any veterinary injector thoroughly after use with iron. For the cleaning procedure, feel free to follow the instructions described in our video above. If you take those steps into account, our applicators will work fine, no matter the product used with it.
