Diagnostica Stago Start 4 Coagulation Analyzer Manual Jun 2026

The manual's instructions for the "Start 4 Pipette Interface" were clear: synchronization was everything. He connected the electronic pipette to the back of the analyzer. This was the "handshake." When Elias dispensed the reagent, the STart 4 would know the exact millisecond the reaction began.

Avoid using metal or magnetic tools near the measurement channels, as this can disrupt the internal magnetic field generation.

Core Measurement Principle: Viscosity-Based Detection System (VBDS)

The analyzer detects this change in motion and immediately stops the internal timer, calculating the precise clotting time in seconds. Step-by-Step Installation and Setup diagnostica stago start 4 coagulation analyzer manual

Diagnostica Stago STart 4 is a semi-automated, benchtop hemostasis analyzer designed for low-to-medium volume laboratories or as a backup for high-throughput automated systems. Its operating manual details a specialized system built around Stago's patented Viscosity-based Detection System (VDS)

The manual, , explained what happened next: “The START 4 uses a 540 nm LED. As fibrin forms, turbidity increases. The analyzer measures the time to reach 50% light transmission—this is your clotting time.”

, including one with a magnetic stirrer to keep reagents homogenous. The manual's instructions for the "Start 4 Pipette

The is a semi-automated, benchtop coagulation analyzer that uses an electro-mechanical detection method known as the Viscosity-based Detection System (VDS) . This system measures the change in plasma viscosity by tracking the movement of a stainless steel ball oscillating in a magnetic field. 1. System Overview

: Use only Diagnostica Stago divisible cuvette strips; these are single-use consumables. Assay Procedure

Includes an RS232-C interface for connection to a Laboratory Information System (LIS). Avoid using metal or magnetic tools near the

: 4 independent channels for clotting-based assays. Incubation Wells : 16 wells (4 columns of 4) maintained at

The manual includes detailed charts for reagent stability (open and closed) specifically optimized for Stago reagents. While this is standard, the clarity regarding on-board stability is helpful for inventory management in smaller labs.

: Load divisible cuvette strips into the incubation wells.
