What is a Science Technician?
Science Technicians provide specialized technical support to scientists and engineers in research, development, and production. This broad category includes roles like Biological Technicians, Chemical Technicians, and Environmental Science Technicians. Their primary duties involve setting up and maintaining laboratory equipment, conducting routine experiments, analyzing samples, collecting data, and recording results. They are critical for the practical execution of scientific projects in laboratories, manufacturing facilities, or field sites.
Typical Education
An associate's degree or a postsecondary certificate in a related scientific or technical field is typically required, though many enter the field with a bachelor's degree in a science discipline.
Salary Range in the United States
The median annual wage for Biological Technicians was $53,440 and for Chemical Technicians was $56,660 as of May 2023.

Day in the Life
How to Become a Science Technician
- Obtain Education: Earn an Associate's degree in a specialized technology field (e.g., Clinical Lab Technology) or a Bachelor's degree in a natural science (Chemistry, Biology).
- Focus on Laboratory Skills: Take laboratory-heavy coursework and seek internships to gain experience with common lab practices (e.g., volumetric measurements, titration, spectroscopy).
- Master Equipment Calibration: Learn to operate, troubleshoot, and calibrate complex analytical instruments relevant to your field (e.g., pH meters, PCR machines, gas chromatographs).
- Develop Documentation Habits: Practice meticulous record-keeping in a lab notebook, focusing on writing clear, detailed procedures and results, which is critical for quality control.
- Seek Certification (Optional): Depending on the field, certification (e.g., Certified Chemical Technician) may improve job prospects, particularly in regulated industries.
Essential Skills
- Laboratory Techniques: Proficiency in sterile techniques, sample preparation, and conducting precise measurements and chemical reactions under supervision.
- Instrumentation Operation: Skill in setting up, monitoring, and maintaining advanced analytical and measurement equipment (e.g., chromatographs, microscopes, environmental sensors).
- Data Recording and Integrity: Meticulous attention to detail for accurately recording raw data and strictly adhering to quality assurance (QA) protocols and Standard Operating Procedures (SOPs).
- Safety and Compliance: Comprehensive knowledge of chemical handling, disposal protocols, and strict adherence to laboratory safety regulations (e.g., OSHA, biosafety levels).
- Basic Data Analysis: Ability to perform routine calculations, interpret charts and graphs, and use spreadsheet software to organize and present findings.
Key Responsibilities
- Preparing and Testing Samples: Collecting, preparing, and analyzing various samples (e.g., chemical compounds, biological cultures, environmental water) using standardized scientific methods.
- Instrument Maintenance and Calibration: Setting up, adjusting, and calibrating laboratory equipment to ensure accurate performance and troubleshooting basic operational issues.
- Conducting Routine Experiments: Carrying out a series of defined tests or experiments according to detailed protocols provided by a scientist or engineer.
- Data Recording and Documentation: Maintaining detailed and accurate laboratory notebooks of all experimental parameters, observations, and raw data for audit and review purposes.
- Inventory and Safety Management: Monitoring chemical and supply inventory, ordering necessary materials, and ensuring the laboratory maintains a clean, safe, and compliant working environment.
