Overview
The BRAND Transferpette S is a precision-engineered, single-channel manual pipette designed for high-reproducibility liquid handling in regulated and research-intensive laboratory environments. Built upon BRAND’s decades-long heritage in German manufacturing excellence, the Transferpette S operates on the air displacement principle—relying on a tightly sealed piston-cylinder system to aspirate and dispense aqueous and low-viscosity solutions with minimal carryover and consistent plunger resistance. Its fully adjustable volume mechanism enables rapid, tool-free setting across a broad dynamic range—from ultra-low volumes (0.1 µL) up to 10 mL—making it suitable for applications spanning molecular biology, clinical diagnostics, quality control testing, and analytical sample preparation. The instrument is manufactured in Germany under ISO 9001-certified processes and conforms to ISO 8655-2 (volumetric performance) and ISO 8655-5 (calibration requirements), ensuring metrological traceability and long-term stability.
Key Features
- German-engineered stainless steel piston and precision-machined barrel for exceptional durability and chemical resistance against common lab solvents, alcohols, and diluted acids/bases.
- Ergonomic, low-force activation requiring only 15–25 N of thumb pressure across the full volume range—reducing operator fatigue during high-throughput workflows.
- Integrated volume lock prevents accidental adjustment during transport or bench use; volume settings are displayed via dual-scale, parallax-free windows with tactile feedback detents.
- Autoclavable tip cone (121 °C, 20 min, 1 bar) and full-disassembly capability for thorough cleaning and maintenance without specialized tools.
- DE-M certified metrological marking per German Measurement Act (Eichgesetz), confirming compliance with national legal metrology requirements for volumetric instruments used in accredited testing laboratories.
- CE-IVD marking indicates conformity with the In Vitro Diagnostic Medical Devices Regulation (EU 2017/746), validating suitability for diagnostic applications where regulatory documentation is required.
Sample Compatibility & Compliance
The Transferpette S delivers optimal performance with water-like liquids (e.g., PBS, Tris-HCl, saline, DNA/RNA dilutions) and exhibits predictable error profiles within ISO 8655-2 Class A tolerances when used with original BRAND sterile filtered tips (e.g., accuTIP™ or sterile BioClean™). It is not recommended for viscous, volatile, or highly corrosive media without prior validation. All units ship with a factory-issued calibration certificate traceable to PTB (Physikalisch-Technische Bundesanstalt), Germany’s national metrology institute. The device supports GLP/GMP-aligned workflows through documented calibration intervals (recommended annually or after 10,000 cycles), and its mechanical design facilitates audit-ready verification using standard gravimetric methods per ISO 8655-6.
Software & Data Management
As a manually operated instrument, the Transferpette S does not incorporate embedded electronics or digital interfaces. However, its metrological integrity integrates seamlessly into electronic lab notebook (ELN) and LIMS ecosystems via standardized calibration record templates and PDF-based certificates. The included calibration certificate contains unique serial number, date of verification, environmental conditions (temperature, humidity), test points (10%, 50%, and 100% of nominal volume), measured deviations, and uncertainty values—all formatted to satisfy FDA 21 CFR Part 11 requirements when archived with appropriate access controls and audit trails. Users may generate supplementary SOPs and equipment logs compliant with ISO/IEC 17025 and CLIA standards.
Applications
- Preparation of calibration standards and reference materials in analytical chemistry and environmental testing labs.
- Serial dilution of genomic DNA, cDNA, and qPCR master mixes in molecular diagnostics and academic research.
- Reagent dispensing in ELISA, lateral flow assay development, and clinical chemistry analyzers.
- Cell culture media and supplement addition under laminar flow hoods, where repeatable low-volume accuracy is critical.
- QC sampling for pharmaceutical raw material release testing, in alignment with USP Analytical Instrument Qualification guidelines.
FAQ
Is the Transferpette S autoclavable?
Yes—the lower tip cone assembly is fully autoclavable at 121 °C for 20 minutes at 1 bar; however, the upper body housing and plunger spring must be disassembled first per the manufacturer’s service manual.
Does it include a certificate of calibration?
Yes—each unit ships with a PTB-traceable calibration certificate covering three volume points, issued at the time of manufacture.
Can it be used with non-BRAND pipette tips?
While functional, using third-party tips may compromise accuracy and repeatability; BRAND recommends accuTIP™ or BioClean™ tips for guaranteed ISO 8655 compliance.
What is the recommended recalibration frequency?
Annually or after 10,000 operating cycles—whichever occurs first—under routine use conditions; more frequent verification is advised in high-precision or GxP-regulated settings.
Is CE-IVD marking sufficient for clinical diagnostic use in the EU?
Yes—CE-IVD certification confirms conformity with essential requirements for in vitro diagnostic devices under Regulation (EU) 2017/746, including performance evaluation and post-market surveillance obligations.
