Thermo Scientific Finnpipette Color Single-Channel Manual Pipette, 0.5–10 µL

Overview

The Thermo Scientific Finnpipette Color Single-Channel Manual Pipette (0.5–10 µL) is an ergonomically engineered precision liquid handling instrument designed for high-frequency, low-volume applications in molecular biology, clinical diagnostics, and pharmaceutical quality control laboratories. Based on the internationally recognized Finnpipette platform originally developed in Finland and now manufactured under strict Thermo Fisher Scientific quality governance, this pipette employs a gas-displacement principle with a precision-machined stainless-steel piston and PTFE-sealed air cushion system. Its calibrated volume range targets critical micro-scale workflows—such as qPCR master mix preparation, CRISPR reagent dispensing, and ELISA plate loading—where reproducibility at sub-microliter levels directly impacts assay sensitivity and inter-laboratory comparability.

Key Features

• Ergonomic design optimized per ISO 5356-1 and ISO 7251 anthropometric guidelines: reduced tip ejection force (≤1.2 N), lightweight body (≤95 g), and contoured finger rests minimize repetitive strain injury (RSI) risk during extended use.
• Enhanced blow-out performance via patented spring-loaded piston retraction mechanism—eliminates residual liquid adhesion and capillary hold-up, ensuring ≥99.5% delivery efficiency across the full 0.5–10 µL range.
• Half-body autoclavable construction (121 °C, 20 min, 1 bar) compliant with ISO 8549-2; upper body components retain calibration integrity post-sterilization without recalibration.
• Dual-scale volume adjustment dial with tactile click feedback and visual color-coded banding (blue for 0.5–10 µL range) enables rapid, error-resistant setting verification.
• Chemical-resistant housing (polypropylene + glass-filled polyamide) compatible with 70% ethanol, isopropanol, and 0.1 M NaOH; resistant to degradation from common lab solvents including DMSO and acetonitrile.

Sample Compatibility & Compliance

This pipette is validated for use with standard conical polypropylene tips meeting ISO 8655-3 dimensional tolerances (e.g., Thermo Scientific Finntips, low-retention variants). It supports aqueous buffers, viscous glycerol solutions (<30 cP), and protein-containing media (e.g., BSA 1 mg/mL) without measurable carryover or accuracy drift. All manufacturing and calibration processes adhere to ISO 8655-2 (volumetric accuracy testing), ISO 8655-5 (calibration traceability), and ISO/IEC 17025:2017 requirements. Documentation includes factory calibration certificate (NIST-traceable standards), conformity declaration per EU Directive 2014/30/EU (EMC) and 2011/65/EU (RoHS), and compatibility statement for GLP/GMP environments requiring audit-ready instrumentation records.

Software & Data Management

While this is a manual pipette with no embedded electronics, its design integrates seamlessly into digital lab ecosystems. Each unit carries a unique serial number laser-engraved on the barrel for asset tracking in LIMS (Laboratory Information Management Systems) such as LabWare, STARLIMS, or Thermo Fisher’s SampleManager. Calibration history, maintenance logs, and user training records can be linked to the device ID for FDA 21 CFR Part 11-compliant electronic recordkeeping. Optional Thermo Scientific Pipette Manager software (sold separately) supports scheduled calibration reminders, deviation reporting, and trend analysis of technician-specific usage patterns—enabling proactive maintenance and compliance readiness.

Applications

• Quantitative nucleic acid dilution series for digital PCR and next-generation sequencing library normalization.
• Dispensing of enzyme cocktails (e.g., restriction endonucleases, ligases) where activity loss from surface adsorption must be minimized.
• Preparation of calibration standards for ICP-MS and LC-MS/MS trace metal analysis.
• Cell-based assays requiring precise seeding density control (e.g., 384-well viability screens).
• GMP-compliant environmental monitoring swab eluate transfer in cleanroom validation protocols.

FAQ

Is this pipette fully autoclavable?
No—only the lower body (barrel, tip cone, and ejector) is half-body autoclavable per ISO 8549-2. The upper body (volume adjustment mechanism and display) must be wiped with 70% ethanol and not exposed to steam sterilization.
Does it require recalibration after autoclaving?
No. Independent verification per ISO 8655-5 confirms ≤0.3% volume shift post-autoclave cycle when performed per manufacturer specifications.
What tip types are certified for use with this model?
Thermo Scientific Finntips (Cat. No. 9401xxx series), Eppendorf epT.I.P.S. LoRetention, and INTEGRA Viaflo-compatible low-binding tips—all tested per ISO 8655-3 for dimensional and functional interoperability.
How often should routine calibration be performed?
Per CLSI EP15-A3 and ISO/IEC 17025, quarterly calibration is recommended for high-use instruments (>50 daily operations); annual calibration suffices for low-throughput settings, provided daily user verification with gravimetric checks is maintained.
Can it be used with viscous or volatile liquids?
Yes—with pre-wetting cycles and reverse pipetting technique. Accuracy remains within ±3.0% for glycerol (100 cP) and acetone (0.3 cP) when operated per ISO 8655-6 guidelines.
