By means of the first brush of this product you can retrieve tissue-odds out of the biopsy channel. With the second brush you can bring out remaining contamination. This allows double cleaning in one process and means working facilitation. * Two brushes clean the biopsy channel in half the time. » Texturized catheters with grip for save handling of slippy instruments, * Soft speacially shaped bristle made of nylon for better cleaning performance. » Rounded tip made of plastic protecting the working channel against damage. * The single-use avoids cross contamination between endoscopes and similar devices.
