1. Why Maintenance Matters
Regular maintenance of benchtop pipettors ensures:
- Accuracy: Consistent and precise liquid handling for experiments.
- Longevity: Prolonged lifespan of the instrument.
- Cost-Effectiveness: Prevents the need for expensive repairs or replacements.
- Compliance: Meets laboratory standards and quality control requirements.
2. Daily Maintenance Tips
Incorporate these steps into your daily routine to maintain optimal performance:
- Inspect the Pipettor: Check for visible damage, wear, or residue on the pipettor.
- Clean Exterior Surfaces: Use a lint-free cloth and ethanol or isopropanol to clean the exterior.
- Check Tip Compatibility: Ensure tips fit securely without leakage.
- Store Upright: Use a pipettor stand to prevent contamination and misalignment.
3. Monthly Maintenance Tips
Set aside time each month for deeper maintenance:
- Disassemble and Clean: Remove the tip cone and piston assembly for thorough cleaning.
- Inspect Seals and O-Rings: Check for cracks, wear, or damage and replace if necessary.
- Lubricate Moving Parts: Use pipettor-compatible grease to ensure smooth operation.
- Test Calibration: Verify the accuracy of liquid volumes using a calibration kit.
4. Annual Maintenance and Calibration
At least once a year, conduct professional calibration and servicing:
- Send to a Certified Service Provider: Partner with experts like Sequence Biotech for comprehensive calibration and part replacement.
- Replace Wear Items: Update pistons, seals, and other consumables as needed.
- Document Calibration: Maintain records to comply with audit and regulatory requirements.
5. Troubleshooting Common Issues
If your pipettor isn't performing optimally, consider these solutions:
- Leaking Tips: Check for damage to the tip cone or improperly seated tips.
- Inconsistent Volumes: Inspect seals and calibrate the pipettor.
- Sticking Piston: Clean and lubricate the piston assembly.
6. Pro Tips for Longevity
Extend the lifespan of your benchtop pipettors with these strategies:
- Use Compatible Consumables: Avoid damage caused by poorly fitting pipette tips.
- Avoid Overuse: Rotate between multiple pipettors to prevent wear from high-frequency use.
- Handle with Care: Prevent accidental drops or misuse that can damage internal components.
