Bioburden Enumeration & Recovery
Count viable microorganisms on a product before sterilization or during process investigation. Recovery efficiency and neutralization are part of the method, not optional corrections.
Methods, applicability and limitations
High-level scope references only, not standards text or a claim about a current edition. Confirm product applicability, adopted edition, jurisdiction and provider authorization before ordering.
- ISO 11737-1 concerns determination of microbial populations on products; distinguish enumeration from sterilization-process validation.
- Define extraction, agitation, filtration or plating, incubation and recovery-efficiency assessment for the actual product.
- Preservatives and antimicrobial surfaces can suppress recovery. Agree neutralizers, controls and method-suitability evidence.
Sample and project requirements
No universal sample quantity is promised. Ask the receiving provider to confirm containers, minimum amount, preparation, hazards, storage, transport and acceptance before collection or shipment.
- Product materials, size, surfaces, manufacturing stage and antimicrobial ingredients
- Representative lot sampling, destructive preparation permission and shipping/storage limits
- Report counts per defined unit, recovery approach, controls and organism characterization
Compare provider proposals
- Request the selected method, suitability work, controls, detection/reporting limits and stated exclusions.
- Confirm relevant experience, actual accredited or authorized scope where needed, subcontracting and quality responsibilities.
- Agree raw data, reviewed results, interpretation, confidentiality, price and a provider-confirmed schedule.
- Laboratory Vortex coordinates requests; independent providers perform the work. No capability, award, compliance or turnaround guarantee is implied.
