Overview
The Thermo Scientific Finnpipette F2 is a precision-engineered, adjustable-volume air-displacement pipette designed for high-reproducibility liquid handling in regulated and research-intensive laboratory environments. Built upon the ISO 8655-2:2022 standard for piston-operated volumetric apparatus, the F2 integrates an Advanced Volume Guard (AVG) system — a thermally isolated, self-supporting volume adjustment mechanism physically decoupled from the pipette barrel. This architectural separation minimizes thermal drift induced by operator hand contact, directly improving both accuracy (±0.5–1.0% depending on range) and repeatability (CV ≤ 0.2–0.6%) across its full operating range. The device employs a dual-piston design for low-volume models (≤50 µL), enhancing blow-out efficiency and reducing residual liquid retention. Its fully autoclavable construction — validated for 121 °C, 20-minute steam sterilization without disassembly — ensures compliance with biosafety Level 2+ workflows and supports routine decontamination in molecular biology, clinical diagnostics, and pharmaceutical QC labs.
Key Features
- Advanced Volume Guard (AVG) system: Thermally insulated volume adjustment module eliminates conductive heat transfer from hand to piston assembly, stabilizing calibration integrity during extended use.
- Ergonomic low-force operation: Plunger activation force remains below 1.5 N across all volume ranges; hook-shaped finger rest enables secure, grip-free handling during repetitive dispensing cycles.
- Vernier-scale volume display: White-background, black oversized digits with integrated 0.1-unit vernier scale provide unambiguous visual confirmation of setpoint; mechanical detents ensure discrete, tactile feedback at each graduation.
- Dual-control button architecture: Top rotary cap delivers consistent aspiration/dispense stroke control; bottom-dedicated volume adjustment dial permits fine-tuning without compromising pipette orientation or grip stability.
- Full-system sterilization capability: Compatible with standard laboratory autoclaves (121 °C, 20 min, saturated steam) and UV-C irradiation (254 nm, ≥30 min), eliminating need for component disassembly prior to decontamination.
- Modular service design: All critical wear components (seals, springs, piston assemblies) are replaceable using only the included calibration toolkit — no proprietary tools or technician dispatch required.
Sample Compatibility & Compliance
The Finnpipette F2 maintains metrological traceability to NIST-certified reference standards and conforms to ISO 8655-2:2022 (accuracy and precision requirements), ISO 8655-5:2022 (calibration procedures), and ISO 8655-3:2022 (tip compatibility). It is certified to ISO 9001:2000 and ISO 13485:2003 quality management systems, and bears CE marking under the EU Medical Device Regulation (MDR 2017/745) Annex II. For GLP/GMP environments, the included web-based Pipette Calibration Software supports 21 CFR Part 11-compliant electronic records, including user authentication, audit trails, and immutable calibration history export (CSV/PDF). Tip compatibility extends across all ISO-standard conical polypropylene tips (e.g., 10–1000 µL universal-fit, low-retention, and filter tip variants), ensuring interoperability with existing consumables infrastructure.
Software & Data Management
Thermo Fisher’s Pipette Calibration Software is a browser-based application compatible with Windows, macOS, and ChromeOS. It guides users through ISO 8655-5-compliant calibration workflows, automatically calculating deviation, repeatability, and linearity metrics against entered reference values. Each calibration session generates a timestamped, digitally signed report with embedded instrument ID, operator credentials, environmental conditions (ambient temperature/humidity), and pass/fail status per ISO tolerance bands. Audit logs record all user actions — including parameter edits, report exports, and software updates — satisfying ALCOA+ data integrity principles. Calibration certificates are exportable in PDF/A-1b format for archival in LIMS or QMS platforms.
Applications
The Finnpipette F2 is routinely deployed in applications demanding strict volumetric fidelity and operational robustness: qPCR master mix preparation, ELISA plate loading, cell culture media aliquoting, HPLC sample dilution, clinical specimen partitioning, and raw material assay in pharmaceutical manufacturing. Its low dead-volume design and high blow-out consistency make it particularly suited for viscous reagents (e.g., glycerol-containing buffers, serum supplements) and low-surface-tension solvents (e.g., DMSO, ethanol). The color-coded volume-range identification system (per ISO 8655-1:2022) streamlines workflow segregation in multi-user core facilities and teaching laboratories.
FAQ
Is the Finnpipette F2 suitable for use with corrosive or high-volatility solvents?
Yes — all wetted surfaces are constructed from chemically resistant PTFE-coated stainless steel and medical-grade polypropylene. However, prolonged exposure to strong oxidizers (e.g., concentrated HNO₃) or halogenated hydrocarbons (e.g., chloroform) is not recommended.
Can calibration data be exported to our LIMS?
Yes — calibration reports are exportable as CSV or PDF/A-1b files, and the software supports direct API integration with major LIMS vendors via RESTful endpoints.
What is the recommended recalibration interval under ISO 8655-5?
For routine use in non-GxP settings: every 3 months. In GLP/GMP environments: prior to each production batch or daily, whichever is more frequent, with documented verification.
Does the AVG system require periodic maintenance or recalibration?
No — the AVG mechanism contains no moving parts or lubricants; it is statically coupled to the volume adjustment spindle and requires no servicing beyond standard pipette calibration.
Are replacement parts available globally?
Yes — all consumable and repair components (O-rings, piston seals, tip ejectors, volume dials) are stocked by Thermo Fisher’s authorized distribution network and carry standardized part numbers traceable to ISO 8655-6:2022 component specifications.
