Reduce downtime and make sure your rigid endoscopes always perform like new with the PROTECTION1® Rigid Endoscope Partnership Program from KARL STORZ. Join the program and trade in some or all of your old rigid scopes for brand new state-of-the-art KARL STORZ rigid scopes. The scopes you trade in can be from other vendors, and it's OK if they have been repaired by an independent service provider. There's no limit to the number of endoscopes you can trade in, and you can choose any replacement size you want to right-size your inventory. Your new replacement scopes come with three years of comprehensive service coverage.
