Celebrating over 60 years...
...designing, developing and manufacturing innovative platelet technologies that have revolutionized Platelet Function testing in Clinical and Research Laboratories. Providing the most comprehensive platelet tests available from any one company, CHRONO-LOG® Platelet Aggregation and Secretion methodologies have been reliable tools in the diagnosis of platelet function defects, monitoring of anti-platelet drugs and assisting researchers in developing novel therapies.

Testing in whole blood requires less sample, eliminates excessive sample manipulation and has been shown to be more sensitive to the effects of anti-platelet drugs such as Aspirin and Plavix. While improving turn-around time in the Laboratory, Impedance Aggregation has also become more user-friendly with the development of Disposable Impedance Electrodes.

Chrono-log innovation has revolutionized Platelet Function Testing in Clinical and Research Laboratories, providing the most comprehensive platelet tests available from any one company. CHRONO-LOG® Platelet Aggregation and Secretion methodologies have been reliable tools in the diagnosis of platelet function defects such as Von Willebrand Disease, Glanzmann’s Thrombasthenia, Storage Pool Disease and Secretion Defects.

Today, CHRONO-LOG® Platelet Aggregometers and Lumi-Aggregometers are used world-wide in hospitals, medical centers, universities and pharmaceutical companies and we have formed a network of independent distributors on six (6) continents.
