Validation for controlled environments and critical spaces
Operation theatres, cleanrooms, laminar flow cabinets and biosafety cabinets — validated against ISO/IEC 17025:2017-compliant test parameters, with NABL-accredited certification.
Where calibration ends, validation begins
Calibration confirms an instrument reads correctly. Validation confirms the environment it operates in — an operation theatre, cleanroom or biosafety cabinet — actually performs to the standard your patients, staff or products require. Vanavil carries out both, so hospitals and laboratories get one accountable provider for equipment and environment.
Our validation work follows ISO/IEC 17025:2017 procedures and is backed by NABL accreditation — see our Calibration services for instrument-level work.
Environments we validate
OT Validation
Operation theatre environmental validation for patient safety and infection control.
Laminar Flow Validation
Airflow and filtration performance testing for laminar flow work stations.
Biosafety Cabinet Validation
Containment and airflow verification, including UV sterilisation effectiveness.
Cleanroom Validation
Full environmental qualification — particle counts, pressure differential, temperature & humidity.
Temperature & Humidity Validation
Environmental monitoring validation for storage and controlled areas.
Pass Box Testing
Interlocking and air integrity testing for material transfer pass boxes.
PCR Hood Testing
Performance testing for PCR hoods used in molecular diagnostic workflows.
What we measure during validation
Applied across OT, cleanroom, laminar flow and biosafety cabinet validation as relevant to each environment.
- Airborne particle count and cleanroom classification
- Air changes per hour (ACPH)
- Pressure differential between rooms
- Airflow velocity and uniformity
- HEPA filter integrity (PAO/DOP)
- Temperature and relative humidity
- Recovery / clean-up time
- Containment and inflow velocity (LAF & biosafety cabinets)
