Overview
The Eppendorf Research plus Multichannel Pipette is a precision-engineered air-displacement pipetting system designed for high-frequency, multi-well liquid handling in molecular biology, clinical diagnostics, drug discovery, and quality control laboratories. Built upon Eppendorf’s proprietary PhysioCare Concept—a human-centered engineering framework grounded in biomechanical analysis and ISO 8549 ergonomics—the instrument minimizes repetitive strain injury (RSI) risk during prolonged use. Its core operating principle relies on controlled piston movement within a sealed air chamber to aspirate and dispense liquid volumes with traceable accuracy across its full range (0.5–300 µL). Unlike fixed-volume devices, the Research plus enables precise, stepless volume adjustment via a dual-stage rotary dial mechanism, delivering reproducible performance validated per ISO 8655-2:2022 (Piston-operated volumetric apparatus—Part 2: Piston pipettes). All models are fully autoclavable without disassembly—meeting stringent GLP/GMP requirements for contamination-sensitive workflows such as cell culture, PCR setup, and regulated bioassay preparation.
Key Features
- PhysioCare-certified ergonomics: Weighing up to 30% less than previous-generation multichannel pipettes, the Research plus reduces thumb force by up to 45% during volume setting and plunger actuation—validated through electromyographic (EMG) studies under ISO 11228-3.
- Elastic Tip Attachment (ETA) technology: Integrated spring-loaded tip cone delivers consistent, low-force tip attachment and ejection, improving inter-operator reproducibility and reducing tip leakage risk—particularly critical for low-volume transfers (≤10 µL).
- PerfectPiston system: Chemically resistant ceramic-coated piston and optimized seal geometry ensure long-term calibration stability across diverse solvents (including 70% ethanol, DMSO, and aqueous buffers), minimizing drift over >10,000 cycles.
- Density adjustment capability: Allows fine-tuning of aspiration/dispense parameters to compensate for liquid density variations (e.g., glycerol-rich solutions or viscous reagents), enhancing volumetric fidelity beyond standard air-displacement limits.
- Four-digit volume display with magnifying lens: Enables rapid, parallax-free reading under standard lab lighting; digits remain legible after repeated autoclaving cycles.
- Tool-free maintenance design: Quick-release lower sleeve facilitates routine cleaning and inspection of internal components without specialized tools—compliant with ISO 8655-5 maintenance guidelines.
Sample Compatibility & Compliance
The Research plus supports universal compatibility with standard conical polypropylene tips (including Eppendorf epT.I.P.S. LoRetention and sterile filtered variants). It is certified for use with Class I and II biological safety cabinets and laminar flow hoods per NSF/ANSI 49 standards. All units ship with EU Declaration of Conformity (DoC) referencing Directive 2014/30/EU (EMC), 2014/35/EU (LVD), and Regulation (EU) 2017/746 (IVDR) where applicable. Autoclavability is verified per EN 285:2015 (steam sterilizers) and validated for 20 consecutive cycles at 121 °C/20 min without degradation of metrological performance or mechanical integrity.
Software & Data Management
While the Research plus operates as a standalone manual device, its calibration records—including date, operator ID, verification method (gravimetric per ISO 8655-6), and deviation logs—can be integrated into laboratory information management systems (LIMS) via optional Eppendorf LabLog software (v3.2+). The instrument supports audit trail generation compliant with FDA 21 CFR Part 11 when paired with Eppendorf’s certified electronic calibration documentation package, enabling full traceability for GxP-regulated environments.
Applications
- High-throughput plate filling (96-/384-well formats) for ELISA, qPCR, and CRISPR screening assays
- Serial dilution series in assay development and reference standard preparation
- Cell suspension transfer in stem cell expansion and organoid culture workflows
- Reagent addition in HPLC/GC sample preparation and derivatization protocols
- Normalization of nucleic acid concentrations prior to NGS library construction
- Buffer exchange in protein purification and affinity chromatography setups
FAQ
Can the Research plus be calibrated in-house?
Yes—users may perform routine gravimetric calibration using certified weights and distilled water per ISO 8655-6, with optional traceable certificates available from Eppendorf Accredited Service Centers.
Is tip ejection force adjustable?
No—tip ejection force is mechanically optimized via the Elastic Tip Attachment system and is not user-adjustable; however, it remains consistently below 2.5 N across all volume ranges.
Does the density adjustment function require external software?
No—density compensation is implemented via mechanical offset of the piston travel path and is set manually using the secondary dial ring adjacent to the main volume selector.
What is the recommended recalibration interval?
Eppendorf recommends annual verification for routine use; quarterly calibration is advised for applications requiring ISO/IEC 17025 accreditation or regulatory submissions.
Are 8-channel and 12-channel versions interchangeable in terms of tip compatibility?
Yes—both configurations accept the same standardized tip racks and individual tips, ensuring seamless workflow transition between channel formats without retraining or consumable changes.
