Overview
The Thermo Scientific Color-coded 8-Channel Manual Pipette (Finnpipette series, 50–300 µL) is a precision-engineered liquid handling tool designed for high-throughput, parallel dispensing in molecular biology, clinical diagnostics, and quality control laboratories. Based on the proven air displacement principle, this pipette delivers consistent volumetric transfer across all eight channels simultaneously—minimizing inter-channel variability and operator-induced error. Its ergonomic design, low actuation force, and tactile feedback mechanism support extended use without fatigue, while the color-coded volume adjustment ring (yellow-coded for the 50–300 µL range) enables rapid visual identification and reduces protocol errors in multi-assay workflows. Unlike fully autoclavable models, this variant is engineered for half-body sterilization—permitting thermal decontamination of the upper housing and plunger assembly while preserving the integrity of the O-ring seals and spring mechanism.
Key Features
- Ergonomic, lightweight construction with balanced weight distribution to reduce wrist strain during repetitive pipetting cycles
- Color-coded volume setting ring (yellow) aligned with ISO 8655-compliant labeling standards for unambiguous range identification
- Adjustable tip ejection force with dual-stage release—soft for standard tips, firm for high-retention or filtered tips
- Sealed, corrosion-resistant internal components resistant to common solvents including 70% ethanol, 10% bleach, and dilute acids
- Calibration-friendly design: single-screw access to internal spring tension adjustment, compatible with ISO/IEC 17025-accredited calibration services
- Tip compatibility with universal conical polypropylene tips (including low-retention, filtered, and sterile options) per ANSI/ASQ Z540.3 and ISO 8655-2 specifications
Sample Compatibility & Compliance
This 8-channel pipette is validated for aqueous buffers, cell culture media, serum-containing solutions, and moderately viscous reagents (up to 10 mPa·s). It complies with ISO 8655-1 (general requirements), ISO 8655-2 (volumetric performance), and ISO 8655-5 (testing methods) for manual piston-operated pipettes. While not certified for GLP/GMP environments out-of-the-box, its traceable calibration capability and documented maintenance procedures support integration into regulated workflows requiring audit-ready documentation per FDA 21 CFR Part 11 when paired with compliant lab management software. The half-body autoclave compatibility (121 °C, 20 min, 1 bar) meets EN 285 steam sterilization guidelines for reusable laboratory equipment—ensuring microbial reduction without compromising mechanical repeatability.
Software & Data Management
As a manually operated device, this pipette does not incorporate embedded electronics or firmware. However, it is fully compatible with external calibration management systems used in accredited laboratories—including Thermo Scientific’s Pipette Calibration Manager (PCM) software suite and third-party platforms such as LabVantage LIMS and STARLIMS. Users may log calibration history, maintenance records, and operator training status in accordance with ISO/IEC 17025 clause 6.4.10 and CLIA requirements. Optional QR-coded asset tags (sold separately) enable seamless integration into digital inventory tracking systems, supporting preventive maintenance scheduling and audit trail generation.
Applications
- High-density ELISA plate preparation (96-well and 384-well formats)
- cDNA synthesis and qPCR master mix setup across replicate samples
- Cell seeding uniformity validation in drug screening assays
- Quality control testing of buffer batches in biopharmaceutical manufacturing
- Standard curve generation in immunoassay development
- Parallel sample dilution in environmental water testing (EPA Method 1600 series)
FAQ
Is full autoclaving supported?
No—this model is rated for half-body autoclaving only. The lower barrel and tip cone must be removed prior to sterilization to prevent seal deformation and volume drift.
What is the recommended recalibration interval?
Per ISO 8655-6, recalibration is advised every 3–6 months under routine use; more frequently if exposed to corrosive agents or subjected to mechanical shock.
Can this pipette be used with positive-displacement tips?
No—it operates exclusively on the air displacement principle and is incompatible with positive-displacement (capillary) tips.
Does the color coding conform to international standards?
Yes—the yellow band corresponds to the 50–300 µL range per ISO 8655-1 Annex B and Thermo Scientific’s global color-coding matrix.
Is service documentation available in English?
Yes—full technical manuals, calibration worksheets, and disassembly guides are provided in English upon request via Thermo Scientific Technical Support.
