Autoclave & Steriliser Validation
An autoclave that completes its cycle and displays a green light has not necessarily sterilised anything. Chamber temperature, pressure and hold time all have to be right together — and only measurement inside the chamber proves it.
What we service
- Benchtop autoclaves in GP rooms, dental and veterinary practices
- Front-loading and pass-through sterilisers in day clinics and theatres
- Dry-heat sterilisers and instrument washers
- Steam generators and associated pressure vessels
Why the display is not evidence
A steriliser’s own display reports what its internal sensor believes, and that sensor is exactly the thing that drifts. If the probe reads two degrees high, the machine will end its cycle early and still report success. The load comes out hot, wet and unsterile, and nothing on the printout says so.
Validation places independent, calibrated sensors inside the chamber and measures what actually happened to the load:
- Chamber temperature against the machine’s own reading, at the set point
- Pressure correlation — steam at the right pressure for the right temperature
- Hold time at sterilising temperature, not just peak temperature reached
- Heat distribution, so the coolest point in the load still reaches specification
- Door seal integrity, safety interlocks and pressure-relief operation
Servicing that prevents the failure
Most steriliser failures are predictable wear. Door gaskets harden and leak steam, water quality leaves scale on elements and probes, filters block, and safety valves seize from disuse. We service these as part of the visit rather than waiting for a failed cycle to take your instruments — and your theatre list — out of action.
Documentation for inspections
You receive a validation report recording measured chamber conditions against the cycle’s requirements, the reference equipment used and its traceability, plus a service record of parts replaced. It is written to sit in your infection-control file and satisfy SAHPRA and ISO 13485 expectations without further explanation.

Autoclave FAQs
Annual validation is the common interval for practice and clinic sterilisers, alongside your routine chemical and biological indicator checks. Validate sooner after a relocation, a major repair, a change in the loads you process, or any cycle failure — those are the situations where chamber performance is most likely to have changed.
Yes, because a passing cycle is judged by the machine’s own sensor. If that sensor has drifted, the cycle can end early and still report a pass. Independent measurement inside the chamber is what distinguishes "the machine says it worked" from "the load reached sterilising conditions".
Usually not. Validation is performed on site with our own sensors and reference equipment, so the unit stays where it is. If servicing uncovers a fault needing workshop attention, we tell you before anything is removed.
Yes — gaskets, filters and water-treatment consumables are the parts that most often cause cycle failures, and we carry common items. Anything not in stock is quoted upfront before we order it.
Steriliser due for validation?
Book it before your next inspection rather than after a failed cycle.
