About Sadguru Research & Analysis Laboratory
Sadguru Research & Analysis Laboratory is a food and water testing laboratory operating from Saltee Plaza on K B Sarani in North Kolkata. We serve food manufacturers, packaged water plants, restaurants and cloud kitchens, housing societies, hospitals, schools, hotels, industrial units and households across Kolkata and West Bengal.
Our reports are written to be read by someone who has to act on them: every parameter is shown with its test method, the applicable limit and the observed value, so a consultant, an inspector or an equipment vendor can work from the document without calling us for an explanation.
On accreditation, stated plainly
This page will list our accreditations and their certificate numbers once they are in hand. Until then we make no claim to NABL, ISO/IEC 17025 or FSSAI-notified status, and you should treat any laboratory that displays such a claim without a verifiable certificate number with caution. If your submission requires a report from an accredited laboratory, tell us at enquiry stage and we will say so honestly.
What we can and cannot do
- Physical, chemical and bacteriological water analysis
- Food microbiology, pathogens and shelf-life studies

Partner laboratories
Vetted partner laboratories across Kolkata, Mumbai, Delhi and South India support specialised scope routing for tests beyond our own bench.
Who signs your report
Every report is reviewed and signed by a named analyst with their qualification printed beside the signature. An unsigned or anonymously signed report is worth very little to an auditor, and a laboratory that will not name its analysts is telling you something.
