Molecular Devices SpectraMax ABS
Molecular Devices · Model SpectraMax ABS
Eliminate filters Eliminate the need for purchasing and changing out filters with a monochromator-based wavelength selection for visible and UV-visible absorbance. Get consistent results Mix samples thoroughly in microplate wells with user-programmable Automix feature and monitor temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C. Integrate with ease Measure micro-volumes: Compatible with the SpectraDrop™ Micro-Volume Microplate, enabling high-throughput measurement of low volumes (<5um) – ideal for DNA, RNA and protein quantification.
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.
Absorbance / QC out of tolerance
HighSymptoms: Readings biased or noisy, calibration / self-test fails, poor plate-to-plate reproducibility.
Root cause: Lamp / LED ageing, dirty optics or filters, or a filter-wheel fault.
Plate-transport / carriage fault
MediumSymptoms: Plate not drawn in or positioned, carriage-error message, wells read at the wrong position.
Root cause: Worn transport belt / motor or a position-sensor fault.
Wash-manifold fault (washers)
MediumSymptoms: Wells not aspirated / dispensed evenly, high residual volume, needles blocked.
Root cause: Blocked or bent manifold needles, or a pump / vacuum fault.
Filter / optics fault
MediumSymptoms: A specific wavelength reads wrong, filter not found.
Root cause: Damaged interference filter or a filter-wheel position fault.
PC / printer / LIS fault
LowSymptoms: Results will not calculate, print or transfer.
Root cause: Onboard software, printer, or the interface.

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: Absorbance or QC out of tolerance
- Run the self-test and any absorbance-verification plate.
- Clean the optical path and inspect the filters.
- Check the lamp / LED energy and replace it if low.
- Read a known standard / QC plate.
- Escalate an optics / detector fault to the OEM.
Symptom: Plate transport or wash fault
- Clear any jammed plate and check the carriage moves freely.
- Inspect the transport belt and position sensor.
- For a washer, unblock / straighten the manifold needles and check the pump and vacuum.
- Run a wash-performance check (residual volume).
- Replace the belt, needles or pump tubing as isolated.
