Core Roles &

- Responsibilities

- High-Volume Sample Processing: Collect, centrifuge, filter, and dilute routine time-course samples from fermentation bioreactors and chemical reactors.

- Analytical Screening: Run daily quantitative wet chemistry tests, including acid-base/redox titrations, Karl Fischer moisture testing, and gravimetric analysis (TS/VS/TDS/VSS/ etc.), Nitrogen estimation by Kjeldahl method.

- Instrument Sample Queue Prep: Prepare, clean, and pipe complex biomass, biodiesel, and fermentation broth samples into manual sample injection and analysis of vials for downstream HPLC and GC-MS analysis.

- Media &
- Reagent Buffering:

Accurately compound, autoclave, and validate bulk microbial growth media, standard chemical reagents, and chromatographic mobile phases.

- Lab Hygiene &

- Equipment Calibration:

Manage glassware cleaning/sterilization protocols and perform daily standard calibrations on pH meters, analytical balances, and micro-pipettes.

- Data Documentation: Log raw testing metrics and physical measurements accurately into MS Excel sheets or the company Laboratory Information Management System (LIMS).

Required Technical Skills &

- Competencies

- Hands-on Wet Chemistry:



Demonstrated proficiency in manual titrations, solution preparation, molarity/normality calculations, and gravimetric testing.

- Optical Instrumentation: Experience operating UV-Vis Spectrophotometers for biomass optical density (OD) tracking and automated refractometers (Brix mapping).

- Sterile Execution: Foundational understanding of aseptic handling techniques to prevent cross-contamination of fermentation batches.

- Extraction Knowledge: Basic familiarity with solid-liquid and liquid-liquid extraction setups (e.g., preparation for fatty acid methyl ester/FAME analysis).

- Safety &
- Compliance:

Strict adherence to chemical hygiene plans, Material Safety Data Sheets (MSDS), and valuable laboratory practices (GLP)

Educational Profile &

- Qualifications

- Degree: Bachelors or Master’s degree (B.Sc. / M.Sc.) in Analytical Chemistry, General Chemistry, Biochemistry, or Microbiology / Biotechnology.

- Experience: 0 to 3 years of hands-on experience in an industrial R&D;, environmental testing, or academic research wet laboratory.
