The E-Pipette series represents ConductScience's electronic pipetting solution for precise liquid handling across laboratory applications. Available in six volume configurations ranging from 0.1-10 μL to 500-10,000 μL, each model features electronic volume control with high-resolution increment adjustment for accurate dispensing. The system incorporates digital displays and programmable protocols to reduce operator variability and enhance reproducibility in liquid transfer protocols.
Electronic pipettes address the limitations of manual micropipettes by providing consistent force application and timing control during aspiration and dispensing cycles. The series supports standard pipette tips and integrates with existing laboratory workflows while offering enhanced precision through electronic servo control systems. Digital interfaces enable protocol storage and recall for repetitive procedures commonly required in analytical chemistry, molecular biology, and pharmaceutical applications.
How It Works
Electronic pipettes employ servo-controlled piston mechanisms to achieve precise liquid aspiration and dispensing. The system uses digital encoder feedback to monitor piston position with high resolution, enabling accurate volume control independent of operator hand strength or technique variation. Electronic control circuits regulate the speed and force of piston movement during both aspiration and dispensing phases, ensuring consistent liquid handling characteristics across multiple operators and extended use periods.
Volume selection occurs through digital interfaces that control stepper motor positioning of the piston assembly. Pre-programmed dispensing protocols can be stored and recalled, allowing standardization of complex liquid handling procedures including multi-step dispensing, mixing cycles, and reverse pipetting techniques. The electronic system monitors tip attachment and provides feedback on proper sealing to prevent volume inaccuracies due to poor tip fit.
Calibration systems within electronic pipettes enable periodic verification of volume accuracy using gravimetric methods. Digital displays show real-time volume settings and operational status, while programmable features support advanced pipetting modes including sequential dispensing, dilution protocols, and automated mixing cycles that enhance reproducibility in analytical procedures.

Practical Tips
Perform gravimetric calibration verification monthly using analytical balance and distilled water at room temperature.
Why: Regular calibration monitoring ensures volume accuracy compliance and identifies potential drift before affecting experimental results.
Clean tip cones daily with distilled water and inspect sealing surfaces for residue buildup.
Why: Contamination on sealing surfaces affects volume accuracy and can cause tip attachment problems during pipetting operations.
Pre-wet tips with sample liquid before critical volume measurements to minimize surface tension effects.
Why: Pre-wetting eliminates volume errors caused by liquid retention on dry tip surfaces, particularly important for small volumes.
Program standardized protocols for repetitive procedures and train all operators on stored protocol access.
Why: Consistent protocol execution reduces inter-operator variability and ensures reproducible results across different research sessions.
Check tip attachment security if experiencing volume inconsistencies or air bubbles during aspiration.
Why: Poor tip sealing creates air leaks that compromise volume accuracy and can introduce sample contamination.
Document electronic pipette serial numbers and calibration dates in experimental records for traceability.
Why: Equipment traceability supports quality assurance requirements and enables investigation of systematic errors if detected.
Use appropriate tip types rated for chemical compatibility with samples and reagents being handled.
Why: Chemical incompatibility can cause tip degradation leading to volume errors and potential sample contamination.
Store pipettes in upright position when not in use to prevent contamination of internal components.
Why: Proper storage orientation prevents liquid intrusion into electronic components and maintains calibration stability.
