Laboratory Services

ESI operate the only private laboratory in the central and northern regions of Sarawak that conducts environmental, industrial hygiene and microbiological analyses of water, wastewater and soil samples. The laboratory utilizes state of the art analytical equipment and stringent quality control procedures to ensure prompt, accurate and reproducible analyses within a high quality technical service package.

Laboratory equipment includes a modern (the latest version) gas chromatogram (GC) and an atomic absorption spectrophotometer (AAS). In addition, proven sampling strategies are adopted for conducting environmental monitoring that employ ISO recognized monitoring instruments.
