Overview
The Thermo Scientific Finnpipette Color Series Single-Channel Manual Pipette (5–50 µL) is an ergonomically engineered precision liquid handling instrument designed for high-frequency, low-volume dispensing in molecular biology, clinical diagnostics, pharmaceutical quality control, and academic research laboratories. Based on the proven air-displacement principle, this pipette delivers consistent volumetric performance across its calibrated range through a tightly controlled piston-seal mechanism. Its design integrates decades of human factors research from Thermo Fisher Scientific’s legacy Finnpipette platform—originally developed in Finland—to minimize operator-induced variability and musculoskeletal strain during repetitive pipetting tasks. The instrument operates without electronic components or power sources, ensuring intrinsic reliability, minimal maintenance, and full compatibility with standard ISO 8655-compliant calibration protocols.
Key Features
- Ergonomic Architecture: Lightweight body (≤105 g), contoured finger grip, and low-force plunger activation reduce hand fatigue and cumulative trauma disorders (CTDs) associated with prolonged use—validated per ISO 10993-5 biocompatibility and EN 61326-1 electromagnetic compatibility standards.
- Enhanced Blow-Out Mechanism: Patented retractable piston design increases residual volume expulsion efficiency, minimizing capillary retention and improving delivery consistency—critical for viscous, volatile, or surfactant-containing solutions.
- Half-Body Autoclavability: Upper housing and internal components withstand repeated sterilization at 121 °C, 1 bar for 20 minutes (ISO 17664), preserving metrological integrity while supporting GLP/GMP workflows requiring traceable decontamination.
- Volume Adjustment System: Dual-scale, lockable dial with tactile feedback ensures precise, repeatable setting of volumes within the 5–50 µL range; graduation resolution of 1 µL supports fine-tuned assay optimization.
- Chemical Resistance: Seals and internal surfaces constructed from fluoropolymer-coated stainless steel and PTFE composites resist degradation from common solvents including ethanol, isopropanol, DMSO, and diluted acids/bases.
Sample Compatibility & Compliance
This pipette is compatible with universal conical tip formats (including low-retention and filtered tips) meeting ANSI/SLAS standards for dimensional tolerance. It maintains accuracy when dispensing aqueous buffers (e.g., PBS, Tris-HCl), DNA/RNA solutions, cell suspensions, and protein-containing media (BSA, FBS). Performance adheres to ISO 8655-2 (volumetric accuracy) and ISO 8655-5 (repeatability), with documented uncertainty budgets traceable to NIST-certified reference standards. For regulated environments, the device supports audit-ready documentation under FDA 21 CFR Part 11 when paired with validated calibration management software and logbook practices.
Software & Data Management
As a manual instrument, the Finnpipette Color Series does not incorporate onboard electronics or digital interfaces. However, it fully integrates into laboratory quality systems via external calibration tracking platforms. Users may document usage history, maintenance events, and calibration certificates using Thermo Fisher’s PipetteTrack™ cloud-based asset management module (sold separately), which enables version-controlled records, automated expiry alerts, and exportable PDF reports compliant with ISO/IEC 17025 requirements. Calibration data can be imported into LIMS or ELN systems via CSV or XML schema, supporting ALCOA+ data integrity principles.
Applications
- Preparation of qPCR and RT-qPCR master mixes requiring sub-microliter precision

- Spotting of nucleic acid samples onto microarrays and blotting membranes
- Cell seeding in 96- and 384-well plates for high-content screening
- Standard curve generation in ELISA and multiplex cytokine assays
- Quality control testing of raw materials in ISO 13485-certified medical device manufacturing
FAQ
Is this pipette manufactured in Finland?
No. While engineered to original Finnpipette specifications and quality benchmarks, this unit is assembled and distributed under Thermo Fisher Scientific’s global supply chain network, with final production located in Jiangsu Province, China.
Can I autoclave the entire pipette?
Only the upper body (half-body configuration) is autoclavable at 121 °C for 20 minutes. The lower tip cone and O-rings must be removed prior to sterilization to prevent seal deformation.
What calibration frequency is recommended?
Per ISO 8655-6, calibration should occur before first use, after any impact or disassembly, following extended storage (>3 months), and at intervals aligned with risk assessment—typically every 3–6 months for routine QC labs.
Does it support filtered tips?
Yes. The tip ejection force and cone geometry are optimized for secure engagement with certified filtered tips (0.2 µm hydrophobic PTFE membrane), preventing aerosol contamination and cross-sample carryover.
How does the blow-out enhancement compare to conventional pipettes?
Independent inter-laboratory studies demonstrate a 30–40% reduction in residual volume retention versus legacy designs, particularly at the lower end of the 5–50 µL range, due to dynamic piston retraction during ejection.
