Overview
The BIO-DL Colour Series Single-Channel Adjustable Manual Pipette is a precision-engineered liquid handling instrument designed for reproducible, low-volume dispensing in molecular biology, clinical diagnostics, and pharmaceutical quality control laboratories. Operating on the air displacement principle, this pipette delivers consistent aspiration and dispensing across its calibrated range of 0.5–10 µL—optimized for applications requiring high sensitivity, such as qPCR master mix preparation, CRISPR reagent handling, and nanoliter-scale assay development. Its ergonomic architecture minimizes operator fatigue during extended use, while color-coded volume indicators enable rapid visual identification of nominal settings—a critical feature in high-throughput or multi-user environments where cross-contamination risk and setting errors must be systematically reduced.
Key Features
- Color-coded volume scale and body ring for intuitive, error-resistant identification of nominal ranges (e.g., yellow for 0.5–10 µL)
- Ergonomic design with wide finger rest and lightweight construction (≤95 g), reducing hand strain during repetitive pipetting cycles
- High-precision adjustable volume mechanism with tactile click-stop feedback and lockable volume setting to prevent accidental drift
- Autoclavable tip cone assembly (121°C, 20 min, 1 bar), supporting ISO 13485-compliant sterilization protocols without disassembly
- User-serviceable internal components—including piston, O-rings, and spring—enabling routine maintenance and GLP-aligned recalibration without factory intervention
- Universal tip compatibility with industry-standard conical 200 µL and 300 µL pipette tips from major OEMs (e.g., Eppendorf, Gilson, Thermo Fisher, BRAND)
Sample Compatibility & Compliance
This pipette is validated for aqueous, viscous (up to 50% glycerol), and mildly corrosive solutions (e.g., 1× PBS, 70% ethanol, 0.1 M HCl). It complies with ISO 8655-2:2022 (volumetric performance requirements for air-cushion pipettes) and supports traceable calibration per ISO/IEC 17025:2017 when used with certified reference weights and distilled water at 20°C ± 0.5°C. The device meets essential requirements under the EU Medical Device Regulation (MDR 2017/745) Annex I for Class I non-sterile laboratory equipment and is suitable for use in GMP-regulated environments where documented calibration history and audit-ready records are required.
Software & Data Management
While the pipette itself is fully manual and requires no firmware or software interface, its design integrates seamlessly into digital lab workflows. Each unit includes a unique serial number engraved on the barrel for asset tracking within LIMS or CMMS platforms. Calibration logs—including date, technician ID, test points (0.5 µL, 5 µL, 10 µL), gravimetric deviation, and environmental conditions—can be recorded in accordance with FDA 21 CFR Part 11–compliant electronic notebooks. Optional accessories include a wall-mounted pipette rack (model PR-01) with individual slots labeled by color code, enabling spatial organization aligned with SOP-defined volume zoning.
Applications
- Preparation of high-fidelity nucleic acid dilutions for next-generation sequencing library quantification
- Dispensing of enzyme blends and restriction buffers in genotyping workflows
- Serial dilution of cytotoxic compounds in IC₅₀ assays where sub-microliter accuracy directly impacts dose-response curve fidelity
- Cell culture media supplementation with growth factors at picomolar concentrations
- Quality control testing of diagnostic reagents under ISO 15197:2013 guidelines for point-of-care device calibration verification
FAQ
Is this pipette suitable for handling volatile organic solvents such as chloroform or acetone?
No. Due to potential degradation of internal elastomers and lubricants, this model is not recommended for prolonged exposure to halogenated or highly volatile organics. Use positive-displacement pipettes for such applications.
Can the pipette be recalibrated without sending it to a service center?
Yes. The integrated adjustment screw allows in-lab calibration using standard gravimetric methods per ISO 8655-6. A calibration certificate template and uncertainty budget worksheet are available upon request from BIO-DL technical support.
What is the recommended recalibration interval under routine usage?
For daily use in regulated environments, recalibration every 3 months is advised; for low-frequency use (<5×/week), semiannual verification suffices—provided environmental conditions remain stable and no mechanical shock occurs.
Does the pipette meet USP <1058> Analytical Instrument Qualification criteria?
It satisfies the “Category B” classification (user-operated, non-automated) under USP <1058>. IQ/OQ documentation packages—including dimensional verification, leak testing, and volumetric accuracy verification protocols—are available for download via the BIO-DL Technical Portal.
Are replacement parts (O-rings, pistons, tip cones) available separately?
Yes. All wear components are stocked globally under part numbers listed in the BIO-DL Spare Parts Catalog (Rev. 2024.3), with lead times ≤5 business days for standard orders.
