This device is a semi-automatic injector. The Mesobasic is made in France and operates with two AA batteries. It does come with a skin stabilizer and has the capability for depth adjustment. The operator needs to push the device forward, puncturing the skin to the pre-adjusted depth, the gun then performs the injection. It is priced slightly higher than the Den’hub but well worth the extra money. This device is ideal for the beginner who is looking for an automatic injector to start with. Physicians also often purchase the Mesobasic as a back up gun. It comes with a 1-year manufacturer’s warrantee with an optional extended warrantee.
