Overview
The Genex-1 Series Adjustable Volume Pipettes are precision-engineered manual liquid handling instruments designed for high-reproducibility volumetric transfer in research laboratories, quality control environments, and clinical diagnostic workflows. Built upon a robust mechanical piston-driven displacement principle, these pipettes operate via air-cushion (air-displacement) technology—ensuring consistent aspiration and dispensing across the full volume range from 0.1 μL to 10,000 μL. Each model in the Genex-1 Series adheres to ISO 8655-2:2022 (Piston-operated volumetric apparatus — Part 2: Piston pipettes) for metrological performance, with factory calibration traceable to national standards (e.g., NIM, China). The design prioritizes long-term operator safety and workflow sustainability through evidence-based ergonomic principles validated against ISO 10075-3:2022 (Ergonomic principles related to mental workload).
Key Features
- Ergonomic contour grip geometry reduces ulnar deviation and palmar pressure during repetitive pipetting—clinically demonstrated to lower incidence of hand fatigue and cumulative trauma disorders (CTDs) over extended shifts.
- Modular tip cone assembly allows full disassembly without tools; all polymer components (tip cone, plunger seal, O-rings) withstand autoclaving at 121°C for 20 minutes per ISO 17664-1:2017, enabling strict sterility assurance in cell culture and molecular biology applications.
- Integrated hydrophobic filter barrier (standard on models ≥10 μL) prevents aerosol contamination of internal mechanisms during volatile or viscous liquid handling, extending service life and maintaining accuracy under GLP/GMP conditions.
- Textured polypropylene grip surface provides tactile feedback and slip resistance—even with gloved hands or aqueous solutions present—enhancing control during low-volume (<100 μL) precision transfers.
- Eight calibrated volume ranges available: 0.1–2.5 μL, 0.5–10 μL, 2–20 μL, 10–100 μL, 20–200 μL, 100–1000 μL, 1–5 mL, and 5–10 mL—covering routine assays, qPCR setup, ELISA plate loading, and bulk reagent dispensing.
Sample Compatibility & Compliance
The Genex-1 Series is compatible with standard conical polypropylene tips meeting ISO 8655-7:2022 dimensional tolerances (e.g., universal-fit, low-retention, and filtered tip types). It supports aqueous buffers, saline solutions, ethanol/water mixtures (≤70%), and common cell culture media. For viscous or volatile samples, users are advised to employ reverse pipetting technique per ISO 8655-6:2022 guidelines. All units comply with RoHS 2011/65/EU and REACH SVHC regulations. Calibration certificates include uncertainty budgets aligned with EURACHEM/CITAC Guide CG4 (Quantifying Uncertainty in Analytical Measurement), supporting audit readiness for ISO/IEC 17025:2017-accredited labs.
Software & Data Management
While the Genex-1 Series is a manually operated instrument, its calibration documentation and maintenance logs integrate seamlessly into laboratory information management systems (LIMS) and electronic lab notebooks (ELN). Each pipette carries a unique serial number engraved on the body, enabling traceability across calibration cycles, preventive maintenance schedules, and user assignment records. Optional calibration services include ISO/IEC 17025-accredited reports with full uncertainty analysis, temperature-compensated volume verification (at 20°C ± 0.5°C), and compliance documentation suitable for FDA 21 CFR Part 11 audit trails when paired with validated LIMS platforms.
Applications
- Molecular biology: cDNA synthesis, restriction digest setup, CRISPR guide RNA dilution, and NGS library normalization.
- Clinical diagnostics: Serum/plasma aliquoting, immunoassay reagent dispensing, and calibration curve preparation per CLSI EP10-A3.
- Pharmaceutical QC: Dissolution medium preparation, standard solution dilution for HPLC method validation, and excipient blending trials.
- Academic teaching labs: Foundational pipetting proficiency training with visual volume setting windows and tactile click-stop volume adjustment.
- Biosafety Level 2 (BSL-2) workflows: Filter-tip-enabled handling of infectious agents where aerosol containment is critical.
FAQ
Are Genex-1 pipettes suitable for use with organic solvents such as chloroform or DMSO?
Yes—when equipped with chemically resistant tip cones (optional accessory), but standard configurations are rated for aqueous and polar solvent use only. Consult the chemical compatibility chart before exposure.
Can I recalibrate the pipette in-house using standard gravimetric methods?
Yes—the Genex-1 Series features user-accessible calibration screws and complies with ISO 8655-5:2022 procedures for field adjustment. Full calibration kits and SOP templates are available upon request.
What is the recommended recalibration interval under GxP conditions?
Per ASTM E2798-21 and EU GMP Annex 15, recalibration is required every 3–6 months depending on usage frequency, environmental stability, and risk assessment outcomes.
Do Genex-1 pipettes meet ISO 8655 accuracy and precision specifications?
Yes—each unit undergoes pre-shipment verification per ISO 8655-2:2022 tolerance limits (e.g., ±0.6% at nominal volume for 100–1000 μL range) and includes a certificate of conformance.
Is technical support available for international customers?
Yes—BIO-DL provides multilingual application engineering support and coordinates with local authorized service partners for calibration, repair, and training.
