Overview
The Thermo Scientific Finnpipette Color Single-Channel Manual Pipette (20–200 µL) is an ergonomically engineered precision liquid handling instrument designed for high-frequency, repetitive pipetting tasks in molecular biology, clinical diagnostics, pharmaceutical QC, and academic research laboratories. Based on the internationally recognized Finnpipette platform—originally developed by Labconco and now manufactured under Thermo Fisher Scientific’s quality system—the device employs a spring-loaded air displacement mechanism compliant with ISO 8655-2:2022 for volumetric accuracy and reproducibility. Its core function relies on calibrated piston movement within a sealed chamber to aspirate and dispense defined volumes of aqueous or low-viscosity liquids, with performance validated across temperature ranges of 15–30 °C and relative humidity ≤70%. Unlike electronic pipettes, this manual model delivers consistent mechanical feedback and zero battery dependency—critical for environments requiring long-term operational stability and minimal maintenance overhead.
Key Features
- Ergonomic lightweight design (≤95 g), reducing hand fatigue during extended use—validated via ISO 5349-1 thumb force testing
- Adjustable finger rest and low-force plunger activation (≤1.8 N for full stroke), minimizing strain on wrist flexor muscles
- Patented piston seal geometry enabling >99.5% blow-out efficiency, mitigating capillary retention and residual film formation
- Half-body autoclavable construction (121 °C, 20 min, 1 bar) with chemically resistant PTFE-coated internal components
- Volume adjustment dial with dual-scale readout (µL and %) and positive click-stop at set points for tactile confirmation
- Interchangeable tip compatibility with universal conical tips (ISO 8655-3 compliant) and low-retention variants
- Calibration certificate traceable to NIST standards included; field recalibration supported using gravimetric method per ISO 8655-6
Sample Compatibility & Compliance
This pipette is optimized for aqueous buffers, saline solutions, diluted acids/bases (pH 2–12), ethanol/water mixtures (10 mPa·s), volatile solvents (e.g., chloroform, acetone), or corrosive agents (e.g., concentrated HNO₃, HF). All materials contacting liquid—including piston, O-rings, and tip cone—are certified non-cytotoxic (ISO 10993-5), non-pyrogenic, and free of detectable RNase/DNase activity. The device meets ISO 8655-2:2022 requirements for accuracy (±2.5% at 200 µL, ±3.5% at 20 µL), precision (CV ≤1.0%), and linearity across its operating range. It supports GLP and GMP workflows through documented calibration history, user-accessible service logs, and compatibility with laboratory audit trail systems.
Software & Data Management
As a manually operated instrument, this pipette does not incorporate embedded electronics or firmware. However, it integrates seamlessly into digital lab ecosystems via third-party calibration management platforms (e.g., LabWare LIMS, Veeva Vault QMS) through standardized calibration record templates (PDF/CSV export). Each unit ships with a unique serial number and factory calibration report containing gravimetric test data at three volume points (20 µL, 100 µL, 200 µL), uncertainty budgets, and environmental conditions. Users may generate electronic maintenance logs using Thermo Fisher’s free PipetteTrack desktop application, which supports scheduled recalibration reminders, technician sign-offs, and PDF report archiving aligned with FDA 21 CFR Part 11 principles (when deployed with appropriate IT validation).
Applications
- Preparation of qPCR master mixes and NGS library normalization
- Serial dilution of ELISA standards and antibody titration panels
- Cell seeding in 96-well microplates for cytotoxicity assays
- Sample transfer in clinical chemistry analyzers and hematology workstations
- Reagent dispensing in automated liquid handler deck setup and validation
- Teaching labs requiring robust, student-proof instrumentation with intuitive volume setting
FAQ
Is this pipette fully autoclavable?
No—only the lower half (tip cone, ejector, and shaft) is autoclavable at 121 °C for 20 minutes. The upper body (volume adjustment mechanism and plunger housing) must be cleaned with 70% ethanol and air-dried.
What is the recommended recalibration interval?
Per ISO 8655-6 and typical lab SOPs, recalibration is advised every 3–6 months for daily use, or after any impact event, disassembly, or observed drift in performance.
Can I use filtered tips with this pipette?
Yes—standard universal filtered tips (0.2 µm hydrophobic PTFE) are fully compatible and recommended when handling RNase-sensitive or aerosol-prone samples.
Does it support traceable calibration to national standards?
Yes—each unit includes a certificate referencing NIST-traceable mass standards and gravimetric methodology per ISO 8655-6 Annex A.
How does the blow-out enhancement reduce carryover?
The tapered piston seal creates controlled back-pressure during ejection, ensuring complete expulsion of liquid from the tip interior and eliminating meniscus hang-up caused by surface tension effects.
