Job description

Chemical Technician – Production & Quality Control

• Full-time

Founded in 1976, E K Industries, Inc. (EKI) manufactures high-purity chemical and reagent
solutions used in laboratories, hospitals, and industrial applications nationwide. As an ISO
9001:2015 and ISO 13485:2016 certified manufacturer, EKI upholds rigorous standards for
quality, traceability, and safety across all production operations.

We’re seeking a dependable, disciplined individual with real-world chemistry experience to join
our production laboratory. The Laboratory Production Technician prepares and tests chemical
batches, performs wet-chemistry QC (pH, titrations, spectrophotometric checks), and ensures
every batch meets specification before packaging. This is a hands-on, production-focused
laboratory role—mixing, measuring, cleaning, and documenting work in a regulated, team-
oriented ISO environment under the supervision of the Quality & Regulatory Manager.

Position Summary
The Laboratory Production Technician plays an important role in EKI’s batch production and quality control operations. This position involves preparing, blending, and testing batches of chemical and reagent solutions according to written formulations and laboratory procedures.

Technicians are responsible for performing all tasks associated with laboratory production — from weighing and mixing raw materials to conducting quality control tests such as pH, spectrophotometric, and titration analysis. The role also includes maintaining accurate batch documentation, cleaning and calibrating laboratory equipment, and supporting general lab operations.

This is a hands-on position that requires attention to detail, accuracy in measurement, and consistent adherence to laboratory safety, GMP, and ISO standards.

Key Responsibilities

• Prepare and produce chemical batches according to established formulations and written batch instructions.
• Accurately weigh, measure, and blend components to meet required specifications.
• Filter, label, and package finished laboratory products.
• Perform in-process and final quality control testing (pH, titration, spectrophotometric checks).
• Document all test results and production data accurately within the laboratory record system.
• Calibrate and maintain laboratory instruments (pH meters, spectrophotometers, analytical balances, etc.).
• Maintain laboratory organization, cleanliness, and equipment readiness in accordance with Good Manufacturing Practices (GMP) and ISO 9001:2015 / ISO 13485:2016 requirements.
• Track and maintain inventory of lab materials, chemicals, and packaging supplies.
• Collaborate with the Laboratory Manager and Production team to align daily production with current orders and priorities.
• High school diploma and a minimum of two years of hands-on experience in a chemical laboratory or chemical manufacturing environment required.
• Additional coursework or certification in chemistry, laboratory science, or a related field is preferred.
• Demonstrated proficiency in wet-chemistry testing methods, including but not limited to pH measurement, titration, and solution preparation.
• Experience using laboratory instruments such as balances, pH meters, and spectrophotometers.
• Strong understanding of safe chemical handling and personal protective equipment (PPE) use.
• Dependable, organized, and detail-oriented with strong record-keeping and documentation skills.
• Must be able to lift up to 50 lbs and stand for extended periods.
• Reliable transportation to workplace required.

Compensation and benefits

• Full-time, hourly position (40 hours per week).
• Paid time off (vacation, holiday pay, sick pay)
• Medical/Dental insurance benefit
