NEED REAGENTS? For over 30 years, laboratories have relied on Chrono-log reagents and reagent kits for platelet function testing. We can supply your needs with prompt shipment from stock.

Chrono-log's wide range of Platelet Aggregometers allows you to choose the instrument with the capabilities to meet your particular needs. The NEW Model 700 Aggregometer provides up to four (4) channels of platelet aggregation in either whole blood or PRP with simultaneous measurement of secretion. Other Chrono-log models have single, dual and four sample units are available, with chart recorder outputs or digital computer outputs. Chrono-log supplies Platelet Aggregometers that measure:

OPTICAL AGGREGOMETERS, which measure platelet aggregation in platelet-rich-plasma (PRP), using the turbidometric method developed by Born.

WHOLE BLOOD AGGREGOMETERS which measure aggregation directly in whole blood, a more physiological milieu than PRP, while requiring less patient blood (0.5 mL/test vs. 2.0 mL/test for PRP), reducing labor costs and improving turn-around time for a complete panel(less than 30 minutes in whole blood, 1.5 to 3 hours in PRP). The advantages of the Whole Blood Aggregometers have been well documented in the peer-reviewed literature, as well as by many laboratory directors. A recent study confirms that whole blood aggregation yields information similar to optical aggregation in PRP.

LUMI-AGGREGOMETERS which simultaneously measure aggregation and ATP secretion to provide a quantitative determination of second wave aggregation and to simplify the diagnosis of storage pool defects and the effects of aspirin-like drugs.

INTRACELLULAR IONIZED CALCIUM AGGREGOMETERS, which measure intracellular ionized calcium flux simultaneously with aggregation.

SMALL, LOW COST WBA WHOLE BLOOD AGGREGOMETERS Now available with Disposable Electrodes capability, the Chrono-log WBA provide a front panel digital display of the aggregation amplitude as well as automatic setting of baseline and gain. Easy to use, they are ideal for drug studies and for platelet function testing in small and large laboratories. These low cost Aggregometers measure platelet aggregation directly in whole blood, eliminating the time and expense of preparing plasma. An accurate platelet aggregation result can be obtained within seven minutes of venipuncture.

The WBA is ideal for testing the effects of anti-platelet drugs on platelet function, since platelets are tested in their natural environment. Ease of operation, with automatic setting of baseline and gain and the elimination of sample manipulation, makes it feasible for platelet aggregation to be tested inexpensively in laboratories of any size. User training time is also reduced, resulting in additional cost savings.

The WBA is available as a single channel (Model 591 or 591A) or dual channel (Model 592 or 592A) unit. The "A" after the model number indicates that the WBA has Disposable Electrode capability. The aggregation amplitude in ohms is shown automatically on the front panel display. Analog outputs provide the option to interface a chart recorder for a hard copy record of the aggregation curves.

The WBA is valuable when you must have a rapid, reliable and cost-effective screen to detect specific platelet abnormalities.

Chrono-log Platelet Aggregation Systems are currently in use for the clinical diagnosis of platelet disorders and monitoring the effects of drugs on platelet function. They are also used to study Heparin-Induced Thrombocytopenia (HIT), leukocyte and neutrophil aggregation, and for the measurement of superoxides and free radicals.
