Overview
The Thermo Scientific Finnpipette Color 8-Channel Adjustable Volume Pipette (5–50 µL) is an ergonomically engineered manual multichannel pipette designed for high-throughput, precision liquid handling in molecular biology, clinical diagnostics, and pharmaceutical quality control laboratories. Built upon the legacy of Finnpipette’s ISO 8655–compliant piston-driven positive displacement architecture, this instrument delivers reproducible volumetric performance across all eight channels simultaneously—enabling efficient parallel dispensing into 96-well and 384-well microplates. Its core operating principle relies on air displacement with a calibrated, temperature-stable stainless-steel piston and low-resistance sealing system, minimizing evaporation-induced variability and ensuring consistent aspiration and dispense kinetics across diverse aqueous and low-viscosity reagents.
Key Features
- Ergonomic design with contoured soft-grip handle and integrated finger rest to reduce repetitive strain injury (RSI) risk during extended use—validated per ISO 5349–1 hand-transmitted vibration guidelines.
- Patented spring-assisted plunger mechanism requiring significantly lower actuation force (≤2.2 N for full stroke), reducing operator fatigue during high-frequency pipetting cycles.
- Enhanced blow-out capability via a proprietary retractable piston seal that minimizes capillary holdback and residual droplet formation—critical for viscous or surfactant-containing solutions.
- Color-coded volume adjustment dial and channel indicators (5–50 µL range) support rapid visual verification and error-resistant operation in multi-user environments.
- Half-body autoclavable construction (up to 121°C, 20 min) enables routine decontamination without disassembly; O-rings and seals are certified for ≥20 sterilization cycles.
- Interchangeable tip cones compatible with universal low-retention pipette tips (including filtered and sterile options) meeting ASTM D7212 specifications for tip fit integrity.
Sample Compatibility & Compliance
This pipette is validated for use with standard aqueous buffers (e.g., PBS, Tris-HCl), cell culture media, DNA/RNA dilutions, enzyme solutions, and common organic-aqueous mixtures (≤15% v/v ethanol, ≤5% v/v glycerol). It is not recommended for highly volatile solvents (e.g., chloroform, acetone), corrosive acids/bases, or viscous liquids (>10 mPa·s at 20°C) without prior validation. All performance specifications adhere to ISO 8655–2 (volumetric accuracy) and ISO 8655–5 (mechanical durability). The device carries CE marking under Directive 2014/30/EU (EMC) and 2011/65/EU (RoHS), and conforms to IEC 61326–1 for laboratory equipment electromagnetic compatibility.
Software & Data Management
As a manually operated instrument, this pipette does not incorporate onboard electronics or digital interfaces. However, it supports full traceability within GLP/GMP-compliant workflows through integration with external calibration management systems. Users may log calibration dates, operator IDs, and verification results using paper-based or LIMS-integrated electronic records. Thermo Scientific provides a downloadable ISO 8655–compliant calibration certificate template (Form F-8655-CAL) and recommends annual verification per ASTM E2758–21 guidance for multichannel pipettes. Audit trails for maintenance and calibration history satisfy FDA 21 CFR Part 11 requirements when implemented via validated electronic documentation platforms.
Applications
- High-throughput ELISA and immunoassay plate setup (coating, blocking, detection antibody addition)
- qPCR and RT-qPCR master mix distribution across multiwell plates
- Cell seeding and media exchange in 96-well adherent culture formats
- Serial dilution workflows requiring identical volumes across multiple columns
- QC release testing of raw materials and intermediates in pharmaceutical manufacturing (per USP Analytical Instrument Qualification)
- Genomic library preparation steps including adapter ligation and PCR cleanup transfers
FAQ
Is this pipette fully autoclavable?
No—only the lower half (tip cone, piston shaft, and ejector assembly) is autoclavable at 121°C for 20 minutes. The upper body housing contains non-heat-resistant elastomers and must not be sterilized by steam.
What tip types are compatible?
It accepts standard conical universal-fit tips (0.5–1000 µL nominal capacity) and low-retention filtered tips meeting ANSI/SLAS 4–2004 dimensional tolerances.
Does it meet ISO 8655 accuracy requirements across the full range?
Yes—when used with certified tips and operated according to manufacturer instructions, it achieves ±2.5% accuracy at 5 µL and ±1.0% at 50 µL, satisfying ISO 8655–2 Class A tolerances for multichannel devices.
Can it be used for viscous or volatile samples?
For optimal accuracy, viscosity should remain below 10 mPa·s. Volatile solvents require pre-wetting and reverse pipetting techniques; performance validation is required prior to routine use.
How often should calibration be performed?
Initial calibration upon receipt, then annually—or more frequently if used >100 times per day—per ISO/IEC 17025 and internal SOPs aligned with ISO/IEC 17025 Clause 6.5.
