A chemical technician runs the tests that tell scientists and plant managers what a material actually is and whether it meets spec. You will weigh, dilute, measure, run instruments like HPLC, GC and spectrophotometers, record everything, and flag anything off. The path is friendly to beginners: many labs hire with an associate degree or a bachelor's in chemistry, and some hire strong high school graduates with lab coursework. Build in this order: safe lab habits and solution math first, then core wet-chemistry and instrument methods, then data, quality systems and troubleshooting. Every skill

Stage 1 of 3 · about 10 weeks
Work safely at a bench, do accurate solution math and basic measurements, and keep a clean record of what you did.
Lab safety and hazard communication
Safety is the first thing a lab teaches and checks. You handle acids, solvents and unknowns, so you must read hazards before you touch anything. OSHA's Hazard Communication and Laboratory Standards are the rules employers follow.
General chemistry essentials
Every test rests on moles, concentration, stoichiometry, acids and bases and gas laws. If you understand why 1 M HCl is not the same as 1 N or 1 %, you will avoid costly errors.
Measurement, accuracy and significant figures
A result is only useful if you know how good it is. Balances, pipettes and volumetric flasks each have limits, and rounding wrongly can make a passing sample look failing.
Lab notebook and documentation
In a regulated lab, if it is not written down, it did not happen. Good records follow ALCOA: attributable, legible, contemporaneous, original, accurate.
Excel for lab data
Most labs record and check results in spreadsheets. Formulas, charts and linear fits are daily tools.
