Techne SBH130D/SBH200D
Techne · Model SBH130D/SBH200D
Choice of 130°C or 200°C maximum temperatureDigital setting and displayUniform and stable temperaturesDesigned for the precise heating of test-tubes, micro centrifuge tubes and cuvettes and microtitre plates.The bright, easy to read LED display facilitates very easy setting of the required temperature and also accurate monitoring of the actual temperature.Excellent temperature stability and uniformity is maintained via sensitive electronic controls.Heats to 100°C in less than 12 minutes.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Temperature control fault
MediumSymptoms: Chamber out of set-point range, alarm.
Root cause: Heater element or sensor drift.
CO2 / gas control fault
MediumSymptoms: Gas concentration alarm, contamination risk.
Root cause: Gas sensor or solenoid valve wear.
Door seal / humidity leak
LowSymptoms: Humidity drift, condensation.
Root cause: Aged door gasket.

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 QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Temperature control fault
- Confirm the presentation - typically chamber out of set-point range, alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: heater element or sensor drift.
- 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 temperature sensor 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: CO2 / gas control fault
- Confirm the presentation - typically gas concentration alarm, contamination risk - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: gas sensor or solenoid valve wear.
- 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 cO2 sensor 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.
