Labs use automated instruments, data systems and software that analyze test results. Chemical technicians still prepare samples, run and maintain instruments, follow safety procedures and check whether results make sense.
The short answer: current evidence points to AI helping with data, not replacing lab work. The ILO's 2025 index rates chemical and physical science technicians as not exposed, with a score of 0.26. The US Bureau of Labor Statistics projects 5 percent growth for chemical technicians from 2025 to 2035, faster than average, with about 7,600 openings a year. Projections are estimates, not guarantees.
How exposed chemical technicians are
The International Labour Organization scores occupations' tasks from 0 (cannot be automated with generative AI) to 1 (could be done without a human operator), and groups them into gradients from 1 to 4, with 4 the most exposed; below them sit minimal exposure and not exposed (ILO Working Paper 140, 2025).
| Occupation (ISCO-08) | ILO category | Mean task score (0 to 1) |
|---|---|---|
| Chemical and Physical Science Technicians | Not exposed | 0.26 |
The ILO index measures generative AI, not robots or automated machines.
What the BLS projects
| Occupation | Projected change 2025 to 2035 | Openings a year |
|---|---|---|
| Chemical technicians | Grow 5% | About 7,600 |
The BLS points to the continued need to test new materials and monitor quality, and to greater interest in environmental issues such as pollution control, clean energy and sustainability. Its outlook does not mention AI.
Where AI is helping
- Processing and checking instrument data.
- Spotting out-of-range results and trends.
- Searching methods, standards and safety data.
- Drafting lab reports and records.
What stays with chemical technicians
- Bench work: preparing samples and running tests.
- Instruments: calibrating, maintaining and troubleshooting equipment.
- Safety: handling hazardous chemicals and following procedures.
- Checking AI help: automated analysis and lookups can be wrong, which NIST calls confabulation (NIST AI 600-1). See checking AI output.
How the job is changing
More data comes off each instrument, so data handling skills matter more alongside bench skills. Careful hands-on lab work stays central. This page is general information, not career advice.

Pay and how to get in
The US Bureau of Labor Statistics puts the median annual pay for chemical technicians at $60,390 in May 2025, against $50,980 for all workers. The typical education needed to enter is: associate's degree. See how this job compares in AI exposure by pay and AI exposure by education level.

The BLS points to testing new materials, quality monitoring and interest in pollution control, clean energy and sustainability.
How many chemical technician openings are expected?
The BLS projects about 7,600 openings a year.
What lab work stays human?
Bench work, instrument care, chemical safety and checking automated analysis.
