Under general supervision, to perform routine chemical analyses and laboratory work on samples or specimens in accordance with established standards, procedure and laboratory operational guidelines; to collect samples and to conduct appropriate tests; keep accurate records of test results and procedures used; and to do other work as required.


The Laboratory Technician is a sub-professional class responsible for performing many of the more routine operations and procedures in the laboratory at a chemical laboratory. As knowledge and skill levels accelerate, the incumbent is expected to perform more professional and complex analyses on sample materials, and require less direction.

Laboratory Technician differs from Laboratory Analyst which is the journey-level class responsible for the overseeing and conducting of a wide range of professional, analytical functions. In addition, the Laboratory Analyst oversees all laboratory operations and procedures, provides necessary ministerial support for the lab, and conducts training for the Technician and other staff regarding appropriate laboratory procedures.
