The COLT is an automatic biopsy instrument used for quick, full, and precise bioptic maneuvers. It is versatile, reliable, and easy to use with one hand due to its automatic function and color coded handles for distinguishing various needle sizes. It is also suitable for procedures that need guidance of ultrasound. The COLT's features include fast firing or two-stage firing. Products for CT-guided procedures and endo-urologic use are also available.
