Pipettes precisely measure and transfer small liquid volumes, an essential tool across laboratory research, clinical testing, and quality control applications. We stock single-channel, multi-channel, and electronic pipettes in a range of volume ranges for manual and high-throughput liquid handling.

Manual vs. Electronic Pipettes

Manual (mechanical) pipettes use a spring-loaded piston operated by hand, offering a reliable, cost-effective option for routine pipetting tasks. Electronic pipettes use a motorized piston for consistent, programmable aspiration and dispensing, reducing hand fatigue during repetitive pipetting and improving reproducibility across multiple users.

Single-Channel vs. Multi-Channel Pipettes

Single-channel pipettes transfer one sample at a time, suited for general lab work and low-throughput tasks. Multi-channel pipettes (commonly 8 or 12 channels) transfer multiple samples simultaneously, matched to standard microplate well spacing, significantly speeding up high-throughput applications like ELISA and PCR plate setup.

Volume Range & Accuracy

Pipettes are available in fixed-volume and adjustable-volume models, covering ranges from sub-microliter volumes up to 10 mL or more depending on the pipette. Accuracy and precision specifications should be checked against your application’s requirements, particularly for volumes at the low end of a pipette’s rated range, where accuracy typically decreases.

Calibration & Maintenance

Pipettes should be calibrated on a regular schedule (commonly every 3 to 12 months depending on usage) to verify accuracy and precision remain within tolerance, since seals, pistons, and tips can wear or degrade with repeated use.

Frequently Asked Questions

Should I choose a manual or electronic pipette?

Manual pipettes are a reliable, cost-effective choice for routine work. Electronic pipettes reduce hand fatigue and improve consistency for repetitive or high-volume pipetting tasks, particularly useful in high-throughput lab environments.

Do I need a multi-channel pipette?

Multi-channel pipettes are recommended for high-throughput applications involving microplates, such as ELISA or PCR setup, since they transfer multiple samples simultaneously and significantly reduce setup time compared to single-channel pipetting.

How often should pipettes be calibrated?

Most labs calibrate pipettes every 3 to 12 months depending on usage frequency, with high-use or critical applications often requiring more frequent calibration to maintain accuracy.

Do you provide calibration certificates for pipettes?

Yes, select models are available with a NIST-traceable calibration certificate at the time of purchase. Look for the certification filter above or contact us for a custom calibration request.
