The STart® 4 semi-automated hemostasis analyzer features Diagnostica Stago's patented method of electro-mechanical clot detection (Viscosity-based Detection System). This method eliminates interference from lipemic, icteric or other optically turbid samples or reagents. The STart® 4 analyzer offers programmable and preprogrammed assays with calibration curve storage, four independently-timed incubation stations, electronically-linked multiple pipettor, 40-character liquid crystal display and an internal thermal printer. The lightweight, compact size makes it ideal for low-medium volume batch testing or as a back-up to optical clot detection systems.
