Microbiological Testing

From routine coliform counts to pathogen detection, from surface swabs to environmental monitoring — a dedicated microbiology suite built around BSL-2 practice.

Overview

Microbiological Testing

JEICL operates a dedicated microbiology laboratory with separate clean and dirty zones, Class-II biological safety cabinet, dual autoclaves and multiple incubators (25 °C, 37 °C, 44 °C) to support the full range of indicator-organism and pathogen testing for water, food and environmental samples. Our methods follow IS 1622, APHA, IS 5401, ISO 4833 and FSSAI manual protocols.

Typical Turnaround

Standard samples: 3–7 working days. Urgent / rush testing: 24–48 hours on request, subject to parameter scope.

Reporting

Results issued on an ISO/IEC 17025:2017-aligned test report format with methodology references, measurement uncertainty where applicable, and digital signature of the Technical Manager.
