BRAND Transferpette S Single-Channel Manual Adjustable Pipette

Overview

The BRAND Transferpette S is a precision-engineered single-channel manual adjustable pipette designed for high-reproducibility liquid handling in research, clinical diagnostics, quality control, and pharmaceutical development laboratories. Operating on the air displacement principle, it delivers accurate and consistent aspiration and dispensing across its full volume range—from ultra-low volumes of 0.1 µL up to 10 mL—without requiring electronic components or external power sources. Its robust all-metal shaft construction, combined with a chemically resistant polypropylene body and precision-machined piston system, ensures long-term dimensional stability and resistance to common laboratory solvents and decontamination agents. The Transferpette S is manufactured in Germany under strict adherence to ISO 8655-2 (volumetric performance requirements) and conforms to DIN EN 285 for steam sterilization validation, making it suitable for GLP- and GMP-regulated environments where traceability and process integrity are critical.

Key Features

• Ergonomic Optimization: Engineered with a low actuation force (< 1.5 N for full stroke), shortened plunger travel distance (≤ 12 mm), and balanced weight distribution (≤ 95 g), the Transferpette S significantly reduces operator fatigue during repetitive pipetting tasks—validated through independent biomechanical studies on hand muscle load.
• Volumetric Integrity: Each unit undergoes individual factory calibration against gravimetric reference standards traceable to national metrology institutes (e.g., PTB, NIST). Accuracy specifications meet or exceed ISO 8655-2 Class A tolerances across the entire range, with typical CV values < 0.5% at nominal volume.
• Volume Lock Mechanism: Integrated mechanical volume lock prevents inadvertent adjustment during operation or transport—critical for assay reproducibility and regulatory audit readiness.
• Autoclavability: Fully autoclavable at 121 °C / 2 bar for 20 minutes per cycle without disassembly. Post-sterilization performance verification confirms no measurable drift in volume delivery or seal integrity.
• Tool-Free Calibration: The Easy Calibration system enables user-performed recalibration using only standard certified weights and distilled water—no proprietary tools or service technician required. Calibration data can be recorded in lab notebooks or LIMS-compliant formats.

Sample Compatibility & Compliance

The Transferpette S is compatible with all ISO 8655-3–compliant conical pipette tips, including BRAND’s own sterile, low-retention, and filter tip lines. It handles aqueous solutions, buffers, diluted acids/bases, ethanol/water mixtures, and viscous liquids (up to ~50 cP) when operated with pre-wetted tips and reverse pipetting technique. Regulatory compliance includes conformity with EU Directive 2014/30/EU (EMC), 2014/35/EU (LVD), and CE marking under Annex II self-declaration. For regulated workflows, the device supports ALCOA+ data integrity principles when paired with documented calibration logs and maintenance records aligned with FDA 21 CFR Part 11 expectations for non-electronic equipment.

Software & Data Management

While the Transferpette S is a fully manual instrument with no embedded electronics or connectivity, its design facilitates seamless integration into digital lab ecosystems. Calibration certificates include unique serial-numbered traceability documentation suitable for import into LIMS or ELN platforms. Users may generate standardized calibration reports using BRAND’s free online Pipette Calibration Report Generator (accessible via brand.com/support), which outputs PDFs compliant with ISO/IEC 17025–recommended content structure—including uncertainty budgets, environmental conditions, and operator signatures. All documentation templates align with internal audit requirements for ISO 15189, ISO 17025, and CLIA-certified laboratories.

Applications

This pipette serves as a foundational tool in molecular biology (cDNA synthesis, qPCR setup), cell culture (media and reagent addition), clinical chemistry (calibrator and control dilutions), and analytical sample preparation (HPLC/GC vial loading, standard curve generation). Its wide dynamic range supports both nanoliter-scale enzymatic assays and milliliter-volume buffer preparation—eliminating the need for multiple dedicated pipettes in resource-constrained labs. In teaching laboratories, its intuitive operation and visual volume display support student competency development in Good Pipetting Practice (GPP) as defined by the International Society for Laboratory Automation and Screening (ISLAC).

FAQ

Is the Transferpette S suitable for handling corrosive or volatile solvents?
Yes—its stainless-steel piston and PTFE-coated seals provide chemical resistance to most organic solvents, dilute mineral acids, and bases. However, prolonged exposure to strong oxidizers (e.g., concentrated HNO₃) or halogenated hydrocarbons is not recommended.
Can I use non-BRAND tips with this pipette?
Yes—the Transferpette S adheres to ISO 8655-3 geometry specifications and demonstrates reliable sealing and ejection performance with major third-party tip brands meeting ISO tip dimensional tolerances.
How often should I calibrate my Transferpette S?
Per ISO 8655-5, calibration frequency depends on usage intensity and risk assessment; typical intervals range from every 3 months (high-throughput labs) to annually (low-use settings), always following documented SOPs and post-maintenance verification.
Does the pipette require lubrication during routine maintenance?
No—its sealed piston system is permanently lubricated at manufacture and requires no periodic oiling. Routine cleaning with 70% ethanol and air-drying is sufficient between uses.
What documentation accompanies each unit?
Each Transferpette S ships with a Certificate of Conformance, factory calibration report (including gravimetric test data), DIN EN 285 sterilization validation summary, and multilingual operating instructions compliant with IEC 62366-1 usability engineering requirements.
