Semi Auto Chemistry Analyzer
Introduction
The Semi Auto Chemistry Analyzer is a reliable and cost-effective diagnostic tool that combines manual flexibility with automated precision. In modern laboratories, this analyzer plays a crucial role in biochemical testing for assessing organ function, metabolic activity, and disease markers—making it an ideal solution for small to medium-sized labs.
What Is Semi Auto Chemistry Analyzer?
A Semi Auto Chemistry Analyzer is a clinical laboratory instrument designed to measure biochemical substances in blood and other body fluids. Using the principle of colorimetric photometry, it quantifies compounds like glucose, urea, cholesterol, and enzymes such as ALT and AST. While it requires manual sample preparation and reagent addition, it automates absorbance reading and result computation—balancing precision with affordability for diagnostic labs.
