Providing an efficient solution for low to medium-volume hemostasis laboratories, the Coag4D instrument is a compact, lightweight, manual 4-channel coagulometer designed to include everything that could be improved in its category: it is extremely user-friendly due to its large-sized and robust touchscreen; it has an easy to follow „traffic light guidance system” for error-free sample and test handling, and barcode reading for samples, reagents and test specific parameters with LIS connection through both USB and serial ports. Coag 4D offers the advantages of photo-optical clot detection by turbodensitometry and combines nephelometry and photometry in one instrument. Moreover, it can be conveniently used for D-Dimer testing. The instrument has excellent analytical performance for clotting and immunological assays with a throughput of up to 50 PT/hour used in quick mode with 4 independent channels. The coagulometer comes with a complete reagent system including PT / aPTT both in liquid and lyophilized formats, TT / Fib tests, bi-level controls and calibrator. Additional tests and special tests can be easily configured and adapted on the instrument, further assisted by an automated internal sensitivity setting. The Coag4D system is available both for distribution and customized OEM cooperation.
