Thermo Scientific Harvey Sterilemax
Thermo Scientific · Model Harvey Sterilemax
Largest bench-top sterilizer chamber available, it accommodates three 2-liter Erlenmeyer flasks Non-recirculation option ensures debris and contaminants are not recycled through the sterilizer, keeping the unit running longer with less cleaning Four preset cycle programs allow one-touch operation for liquids, wrapped goods, unwrapped goods and packs The 12" x 18" (30.4 x 45.7 cm) chamber contains removable racks and trays for smaller loads and other unique sterilization requirements Removable racks for easy cleaning Easy-to-read LCD display lets you view sterilization and diagnostic programs and displays all aspects of the cycle for quick visual verification Three locks on the chamber door ensure your safety, so the door will not open until the chamber is depressurized The SterileMax is ASME, UL, CE, and CUL approved and built to AAMI - ST-55 specifications Independent validation testing* for sterility, accuracy, and verification of all programs. Meets all current requirements for tabletop sterilizers.
Key tips
- ·A failed biological indicator means the entire load is not sterile - no exceptions, regardless of how the cycle printout looks.
- ·Door gasket wear is the most common real cause of a failed vacuum/pressure test - check it before deeper diagnostics.
- ·Water quality directly affects steam-cycle validity - don't ignore scale or mineral buildup.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Door gasket / seal leak
HighSymptoms: Pressure loss, long cycle, steam leak.
Root cause: Aged rubber gasket.
Vacuum pump failure
MediumSymptoms: Poor air removal, non-condensable gas fault.
Root cause: Worn vanes/seals.
Chamber temperature sensor drift
MediumSymptoms: Temp out of tolerance, failed Bowie-Dick.
Root cause: Sensor aging.
Water quality / feed fault
LowSymptoms: Scaling, conductivity alarm.
Root cause: RO/DI system failure.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily biological and chemical indicator test loads
- ·Door gasket / seal inspection
- ·Steam trap and drain strainer cleaning
- ·Annual full PM and pressure-vessel certification
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Door gasket / seal leak
- Confirm the presentation - typically pressure loss, long cycle, steam leak - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: aged rubber gasket.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the door gasket / seal per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Steam generator / heater fault
- Confirm the presentation - typically no steam, low temp, cycle abort - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: failed heating element or scale buildup.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the steam generator heating element per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
