Key responsibilities

• Perform routine physicochemical and analytical testing of raw materials, intermediate products and finished products.
• Conduct wet chemistry analyses according to approved laboratory methods and
• Perform routine microbiological testing, including preparation of media, sample preparation, microbial enumeration and related analyses.
• Operate, maintain and perform basic troubleshooting of laboratory
• Prepare reagents, standards, solutions and culture media
• Perform laboratory calculations, record results and maintain complete laboratory
• Assist in method verification, method development and laboratory R&D
• Support sampling, sample preparation, testing and
• Maintain laboratory records in accordance with Good Laboratory Practice (GLP).
• Follow laboratory SOPs, safety procedures and quality control
• Support implementation and maintenance of laboratory systems aligned with ISO/IEC 17025
• Participate in calibration, verification and routine maintenance activities for laboratory
• Identify abnormal results, out-of-specification results and analytical problems and report them appropriately.
• Maintain laboratory cleanliness, organization, chemical safety and good
• Support QC and R&D testing activities as
