Disposable Combination Cleaning Brush, Working length: 2200mm. Designed to facilitate maximum cleaning performance while ensuring compatibility with the endoscope channel. A wide variety of line-up facilitates cleaning of various scopes or different cleaning methods. The plastic tip at the distal end protects the scope from the wire of the brush. The Olympus cleaning brush has thick, stiff bristles that allow it to make better contact with the inside surface of the scope channel when the scope is wound up. All of the bristles touch and bend equally, allowing the brush to make contact with the entire inside surface of the channel. UOM: 50/BX.
