Raypa ID Culture
RARaypa · Model ID Culture
Incubation by natural convection. Setting temperature range from room temperature +5°C to 80°C. Heating by electric elements assembled in an independent chamber for optimal temperature stability. Temperature and time controlled by digital PID microprocessor, with 10 editable programs of customizable name, programmable with up to 10 temperature/time segments. Timer start and timer stop adjustable by date, hour and minute. Intuitive alphanumeric 3,5’’ LCD touchscreen user interface that displays time, temperature and cycles in graphs, has audiovisual alarms and advanced cycle and timer programming.
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not hold set temperature
HighSymptoms: Chamber above or below setpoint, temperature alarm, slow recovery after the door opens.
Root cause: Heater element, a temperature-sensor / controller fault, a door / gasket leak, or a circulation-fan fault.
CO2 concentration fault (CO2 incubator)
HighSymptoms: CO2 above or below setpoint, CO2 alarm, pH drift in cultures.
Root cause: CO2 sensor (TC or IR) drift, an empty / low CO2 supply, or a solenoid / regulator fault.
Humidity fault (CO2 incubator)
MediumSymptoms: Low humidity, plates drying out, condensation problems.
Root cause: Empty water pan, or an evaporation / airflow issue.
Over-temperature safety trip
MediumSymptoms: Chamber stops heating, over-temp alarm, will not restart.
Root cause: Controller / sensor fault driving the heater high, or an independent over-temp thermostat.
Door / gasket fault
LowSymptoms: Door will not seal, temperature swings, condensation at the door.
Root cause: Worn door gasket or a sagging hinge.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set temperature
- Compare the chamber to an independent calibrated thermometer at several points.
- Confirm the door seals and the gasket is intact.
- Check the circulation fan runs.
- Verify the heater draws current.
- Replace the sensor, controller or heater as isolated, then verify stability over several hours.
Symptom: CO2 out of range (CO2 incubator)
- Verify CO2 with an independent calibrated analyser (Fyrite or electronic).
- Confirm the CO2 supply pressure and that the cylinder is not empty.
- Check / calibrate the CO2 sensor per the manual (TC sensors drift with humidity and door openings).
- Inspect the inlet filter and solenoid.
- Recalibrate and re-verify against the reference.
