As a clot forms, the viscosity of the plasma increases.

, focus on these critical sections to ensure seamless operation: 1. The Startup "Self-Check"

16 positions for cuvettes; 2 positions for reagents. Printer Output: Compatible with external thermal printers. Sample Type: Plasma.

The STart 4 is designed for efficient workflow. The following provides a general overview of key daily tasks:

: Remember the "Blue Top" rule—sodium citrate tubes must be filled exactly to the line (1:9 ratio) to ensure accurate results. Final Verdict

: Primarily clotting assays, but also capable of chromogenic and immunoassay methodologies in random access mode. Labexchange.com Maintenance and Troubleshooting Daily Maintenance

The Stago STart 4 is a legendary benchtop coagulation analyzer, widely recognized for its "gold standard" mechanical clot detection system. Whether you are a lab manager setting up a new unit or a technician troubleshooting a measurement, understanding the manual’s core protocols is essential for accurate results.

The sensor detects the exact moment the ball’s oscillation amplitude drops below a predefined threshold. The internal timer stops instantly, recording the precise clotting time in seconds. 3. Installation and Setup

Ensure the cabled pipette is securely plugged into the rear port.

The formation of fibrin increases the sample's viscosity, restricting the movement of the steel ball.
