BRAND Transferpette® S Single-Channel and Multi-Channel Adjustable/Automatic Pipettes

Overview

The BRAND Transferpette® S is a precision-engineered air-displacement pipette system designed for high-reproducibility liquid handling in regulated life science laboratories. Built upon decades of German engineering heritage, it implements a robust, modular architecture centered on ergonomic efficiency and metrological integrity. Its operating principle relies on controlled air displacement within a sealed piston chamber: depression of the central plunger compresses air above the piston, creating negative pressure during aspiration and positive pressure during dispensing—ensuring consistent volumetric delivery across the full range. The system’s design prioritizes operator safety and long-term repeatability, with mechanical stability maintained under repeated thermal cycling and routine sterilization. Unlike disposable or semi-disposable alternatives, the Transferpette® S is engineered as a durable, recalibratable instrument intended for daily use in molecular biology, clinical diagnostics, pharmaceutical QC, and academic research environments where traceability and compliance are non-negotiable.

Key Features

• Ambidextrous central plunger button with independent tip ejection—enabling true one-handed operation for both right- and left-handed users without compromising control or accuracy.
• Full autoclavability at 121 °C and 2 bar pressure—validated for complete sterilization of the entire pipette body, including internal mechanisms, without disassembly.
• Tool-free Easy Calibration system—allows field adjustment of volume output using only the included calibration key; changes to factory-set values are externally visible via a dedicated indicator window.
• Optimized short plunger travel of just 12.5 mm—reducing muscular effort and mitigating risk of repetitive strain injury (RSI) during high-throughput workflows.
• Corrosion-resistant stainless-steel piston and tip ejector assembly—ensuring long-term dimensional stability and resistance to organic solvents, acids, and bases commonly used in sample preparation.
• High-contrast 4-digit LCD display—providing unambiguous volume readout with resolution appropriate to each model’s nominal range (e.g., 0.01 μL for 0.1–1 μL models).
• ISO-compliant color-coding system—aligned with international tip diameter standards (e.g., yellow for 10–100 μL, blue for 100–1000 μL), minimizing user error during tip selection.
• Volume lock function—mechanically prevents accidental adjustment during benchtop transport or multi-step protocols.

Sample Compatibility & Compliance

The Transferpette® S is validated for aqueous, viscous, and volatile liquids—including ethanol, DMSO, glycerol solutions, and enzyme-containing buffers—across its specified volume ranges. It meets essential regulatory requirements for in vitro diagnostic (IVD) applications under the European CE-IVD directive. While not intrinsically GLP/GMP-certified, its design supports compliance with ISO 8655 (pipettes — specification and testing), ISO/IEC 17025 (for calibration laboratories), and FDA 21 CFR Part 11 when integrated into validated laboratory information management systems (LIMS). Autoclaving validation reports and calibration certificates are available upon request for audit readiness.

Software & Data Management

As a manually operated mechanical device, the Transferpette® S does not incorporate embedded electronics or wireless connectivity. However, its Easy Calibration system generates a physical record of adjustments—each change is marked by a visible shift in the calibration indicator window, enabling manual logbook entry per GLP requirements. Laboratories implementing electronic lab notebooks (ELN) may document calibration events, maintenance history, and usage logs alongside instrument IDs for full traceability. Optional accessories include serialized calibration tools and traceable NIST-traceable reference weights for in-house verification.

Applications

• Molecular biology workflows: cDNA synthesis, PCR/qPCR setup, restriction digestion, and CRISPR reagent dispensing—particularly leveraging the 0.1–1 μL model’s enhanced accuracy for low-volume enzymatic reactions.
• Clinical microbiology: serial dilution of bacterial cultures, inoculation of blood agar plates, and preparation of antimicrobial susceptibility test panels.
• Cell culture & immunology: uniform seeding of 96-well plates for ELISA, cytokine assays, and high-content screening; compatible with multi-channel variants for rapid, parallel transfers.
• Pharmaceutical quality control: buffer preparation, standard curve generation, and dissolution testing sample aliquoting where volumetric precision directly impacts assay validity.
• Academic teaching labs: durable construction and intuitive interface support student training in Good Laboratory Practice (GLP) fundamentals and pipetting technique validation.

FAQ

Is the Transferpette® S compliant with ISO 8655?
Yes—the entire Transferpette® S series is manufactured and tested in accordance with ISO 8655-2 (volumetric accuracy) and ISO 8655-5 (calibration procedures). Certificates of conformance are supplied with each unit.
Can I autoclave the multi-channel version without disassembly?
Yes—both single- and multi-channel Transferpette® S models are fully autoclavable as assembled units at 121 °C, 2 bar, for up to 20 cycles without performance degradation.
Does BRAND provide calibration services or certified reference materials?
BRAND offers optional factory calibration services with ISO/IEC 17025-accredited certificates. Traceable gravimetric calibration kits—including Class E2 weights and temperature-controlled balance platforms—are available through authorized distributors.
How often should I recalibrate my Transferpette® S?
Calibration frequency depends on usage intensity and application criticality; BRAN recommends baseline verification before first use, after autoclaving, following impact events, and at least every 3–6 months in routine QC environments.
Are replacement parts and service manuals available globally?
Yes—original spare parts (seals, plungers, tip cones), service toolkits, and multilingual technical documentation are distributed through BRAND’s global network of certified service centers and authorized partners.
