Why one laboratory

One laboratory, seven divisions.

Most preclinical programmes are assembled from three or four vendors, and every boundary between them re-ships material, re-validates methods and loses weeks to email.

Here the divisions share one campus, one quality system, one archive and one chain of custody. Nothing is handed over, because nothing leaves.

One shared quality system

Toxicology

Safety assessments to evaluate toxicity, irritation, sensitisation and potential health effects.

Key capability
Multi-year
Runs with
Vivarium · Chemistry · Custom Studies

Shares one test-item record, one archive and one quality system with every other division.

The connections above are a shared quality system, one test-item record and one archive — not a fixed order of work. Which divisions a programme engages, and in what sequence, follows from the dossier it has to satisfy, and they run in parallel wherever the science allows.

The facility

One accredited site in Salem, Tamil Nadu.

Chemistry, toxicology, ecotoxicology, entomology, microbiology and the vivarium share one address. That is what lets a study change division without changing custodian.

    01Instrument operationEvery instrument qualified, calibrated and logged against the study that used it.
  • NSRL illustration: a glass-fronted containment cabinet lit from within, holding sample plates and pipettes on a stainless deck.
