Variable Volume Pipetting Systems

Variable volume pipetting systems are advanced liquid handling tools designed to dispense liquids with high accuracy and flexibility across a broad volume range. Users can adjust the dispensed volume within a defined setting, making these instruments versatile for diverse laboratory applications. Built from lightweight yet durable materials, they provide ergonomic comfort during extended use and maintain long-term reliability.

Available in a broad range of volumes from microliters to milliliters, adjustable designs deliver precise control, reproducibility, and universal tip compatibility. Many models are fully or semi-autoclavable, supporting safe maintenance and reducing cross-contamination risk. By combining precision, durability, and adaptability, variable volume micropipettes offer best-in-class performance for routine tasks and demanding research, from small-scale assays to large-volume handling. Compared with fixed volume formats, single channel options enable consistent, traceable transfers across workflows.

Key Features of Ergonomic Pipette Design, Volume Control, and Electronic Pipettes

• Ergonomic design for comfort: Ergonomic geometry reduces hand fatigue and supports neutral grip posture for sustained use with manual pipettes.
• Precise volume control: Finely adjustable volume settings, with increments from 0.05 µL to 10 µL (depending on the model), ensure accurate and reproducible liquid handling.
• Digital display and smooth adjustment: Clear display and smooth-turning control enable rapid volume verification and intuitive adjustment during high-throughput protocols.
• Autoclavable and UV sterilizable construction: The pipettes have components that support sterile technique and minimize cross-contamination in sensitive environments.
• Durable and chemically resistant materials: Robust, chemically resistant construction (for example, polycarbonate composites) enhances durability and reliability over repeated cycles.
• Secure volume lock mechanism: A volume lock prevents inadvertent changes during repetitive dispensing, preserving consistency in single channel workflows.
• Efficient blow-out and tip compatibility: The design reduces sample retention and improves transfer fidelity across micropipettes and electronic pipettes.
• Easy disassembly for maintenance: Tool-less disassembly streamlines cleaning and routine servicing, maintaining performance without complex maintenance.

Applications: Large-Volume Precision with Manual Pipettes, Electronic Pipettes, and a Micropipette Set

• Molecular biology: The pipetting systems are widely used for the preparation of PCR reactions, DNA/RNA extraction, and sequencing workflows with precise, adjustable aliquots to protect data quality.
• Cell culture: In cell culture, these systems help in media preparation, cell seeding, and the addition of growth factors or drugs with controlled transfers that help limit cross-contamination.
• Biochemistry & enzymology: They are essential for dispensing substrates, cofactors, and inhibitors for kinetic assays requiring reproducible timing and volumes.
• Clinical diagnostics: The systems are used in standardized patient sample preparation, dilutions, and reagents for ELISA and qPCR to support traceability and comparability.
• Pharmaceutical research: In drug discovery, the pipettes are used for dose-response studies and compound dilution, supporting high-throughput screening and maintaining rigorous liquid accuracy.
• Environmental & food testing: They play a role in reliable handling for contaminant assays and microbial testing, ensuring consistent, compliant sample preparation.
• Analytical chemistry: The pipetting systems are critical for precise sample prep in HPLC, GC, and mass spectrometry, safeguarding uniform injection quality and instrumental robustness.
