Pipette FAQ Section
Q: How often should I calibrate my pipette?
A: For optimal performance, we recommend calibrating your pipette every 3-6 months, depending on usage frequency. Heavy daily use may require monthly calibration. Always calibrate after any maintenance or if you suspect inaccurate measurements.
Q: What's the proper way to store pipettes when not in use?
A: Store your pipette in an upright position using a pipette holder. For extended storage (more than 2 weeks), set the volume to the maximum capacity to relieve spring tension. Keep in a clean, dry environment away from direct sunlight.
Q: Can I use different brands of tips with your pipettes?
A: While our pipettes are designed for universal tip compatibility, we recommend using manufacturer-approved tips for best results. Third-party tips may affect accuracy and precision due to variations in manufacturing tolerances.

Choosing the Right Pipette
Selecting the appropriate pipette depends on several factors including required volume range, frequency of use, and application requirements. For general laboratory work, adjustable volume pipettes offer the most versatility. For specialized applications like PCR work, consider fixed-volume pipettes for maximum precision.

Q: What's the difference between air displacement and positive displacement pipettes?
A: Air displacement pipettes (standard type) use an air cushion to move liquid and work well for aqueous solutions. Positive displacement pipettes use a disposable piston that contacts the liquid directly, making them better for viscous, volatile, or dense liquids.
Q: How should I clean a contaminated pipette?
A: First, disassemble according to manufacturer instructions. Clean all parts with mild detergent and distilled water, then rinse thoroughly. For decontamination, autoclave at 121°C for 15-20 minutes or soak in appropriate disinfectant solution.
Q: Why does my pipette produce inconsistent results?
A: Inconsistent results can stem from several issues: worn piston seals, improper tip attachment, temperature differences between liquid and pipette, or calibration drift. Try changing tips, checking seal condition, and allowing equipment to temperature equilibrate before recalibrating.
Pipette Usage Tips
- Always pre-wet tips by aspirating and dispensing liquid 2-3 times before final measurement
- Hold pipette vertically when aspirating and at 45° angle when dispensing
- Use smooth, controlled plunger movement for best accuracy
- For small volumes, pause briefly after aspiration to ensure complete liquid transfer
- Never lay a pipette with liquid in the tip on its side
