?Compact analyzer for turbidimetric reading with built-in printer. Perfect for all kinds of laboratories, the Wiener lab. Col 4 is the ideal way to systematize all routine determinations from the Coagulation Department, complying at the same time with the Quality Control regulations. Procedure Wiener lab. Col 4 is a compact 4-channels analyzer whose principle of measurement is Turbodensitometry. When the starter reagent is added, and as the clot is formed, the passage of light begins to decrease. A small steel cylinder is magnetically stirred inside the cuvette in order to keep the particulate reagents in suspension. At a certain level, the reaction stops and the instrument informs and prints the obtained values. The different functions are selected on the liquid crystal screen. The instrument is also provided with a standard RS 232 output port. The reagents and samples block, heated through Peltier system, contains 1 measuring cell with a magnetic mixing motor, one reagent position and 16 positions for reaction cuvettes. Technical features Action principle: Turbodensitometric. Reading cuvettes: microcuvettes. Total volume: 150-300 µl Display: LCD (Liquid Crystal Display) – 2 line of 20 characters Control Panel: membrane keyboard. Memory: maximum storage of 7 methods.
