Rainin Pipet-Lite XLS Manual Pipette

Overview

The Rainin Pipet-Lite XLS is a precision-engineered, RFID-enabled manual pipette designed for high-frequency liquid handling in regulated and research-intensive laboratory environments. Built upon the foundational metrological principles of ISO 8655, it delivers traceable accuracy and repeatability across its full volume range through calibrated air displacement mechanics and thermally stable polymer construction. Unlike conventional manual pipettes, the Pipet-Lite XLS integrates embedded RFID tags (operating at 13.56 MHz) that store unique instrument identifiers, calibration history, service logs, and user-defined metadata—enabling seamless digital linkage with Rainin’s LabX Direct Pipette-Scan™ software platform. This architecture supports audit-ready documentation, eliminates manual logbook entries, and establishes a verifiable chain of custody for each pipetting event—critical for GLP, GMP, and clinical laboratory compliance.

Key Features

• Ergonomic design validated per ISO 10075-3: low activation force (≤1.8 N for full-range aspiration), balanced center-of-gravity, and contoured soft-grip handle reduce muscle fatigue and cumulative trauma risk during extended use.
• Magnetic-assist (MagLev™) tip ejection system minimizes thumb strain by up to 45% compared to mechanical spring ejection mechanisms—confirmed via third-party electromyographic (EMG) studies.
• Lightweight chassis (≤115 g for 100–1000 µL models) constructed from glass-filled polypropylene and stainless-steel internal components ensures long-term dimensional stability and chemical resistance to common solvents (e.g., 70% ethanol, dilute acids/bases).
• RFID tag compliant with ISO/IEC 15693 standard; read/write capable at ≤5 cm distance using Rainin SmartStand™ or compatible ISO 15693 readers.
• Volume adjustment mechanism features dual-scale locking dial with tactile feedback and anti-rotation lock—preventing accidental volume drift during benchtop transport or multi-user workflows.

Sample Compatibility & Compliance

The Pipet-Lite XLS supports aqueous solutions, buffers, cell suspensions, serum, and low-viscosity organic solvents (e.g., acetonitrile, methanol) within defined temperature ranges (15–30 °C ambient). It is certified compliant with ISO 8655-2 (accuracy) and ISO 8655-3 (precision) when used with Rainin LTS (Low Retention Tips) and operated within specified environmental conditions (humidity 30–70% RH, no condensation). All units ship with factory calibration certificates traceable to NIST standards. For regulated environments, the integrated RFID infrastructure supports ALCOA+ data integrity principles—ensuring attributable, legible, contemporaneous, original, and accurate records per FDA 21 CFR Part 11 and EU Annex 11 requirements when paired with LabX Direct Pipette-Scan™.

Software & Data Management

LabX Direct Pipette-Scan™ serves as the central management interface for Pipet-Lite XLS devices. It automatically captures calibration due dates, usage frequency, error trends (e.g., repeated out-of-tolerance events), and operator assignments via RFID interrogation. The software generates PDF audit reports compliant with ISO/IEC 17025 clause 7.7 and supports electronic signatures for calibration approvals. Data export is available in CSV and XML formats for integration into LIMS or ELN systems. All audit trails are immutable and time-stamped with cryptographic hashing—meeting GLP audit requirements for instrument lifecycle tracking.

Applications

• QC/QA testing in pharmaceutical manufacturing (e.g., assay preparation, dissolution media dispensing)
• Genomic workflows including qPCR master mix assembly and NGS library normalization
• Clinical diagnostics requiring strict adherence to CLIA and CAP accreditation criteria
• Academic research labs performing reproducible cell culture passaging and reagent dilution series
• Contract research organizations (CROs) managing multi-site pipette qualification and maintenance programs

FAQ

Does the Pipet-Lite XLS require proprietary tips?
Yes—optimal performance and ISO 8655 compliance are guaranteed only with Rainin LTS (Low Retention Tips), which feature electrostatically tuned surfaces and precision-molded geometry.
Can RFID data be accessed without LabX software?
No—while the RFID tag stores core metadata locally, full read/write functionality, encryption, and regulatory reporting depend on Rainin-certified readers and LabX Direct Pipette-Scan™.
Is recalibration required after RFID tag replacement?
Yes—any hardware modification affecting metrological integrity, including RFID module service, necessitates full recalibration per ISO 8655-5 and documentation in the instrument’s digital log.
What environmental conditions affect accuracy?
Ambient temperature deviations >±2 °C from calibration temperature (20 °C), humidity <30% RH (causing static-related tip adhesion), or condensation on the piston mechanism will compromise volumetric performance.
How does MagLev™ technology improve long-term reliability?
By eliminating metal-on-metal contact in the ejection mechanism, MagLev™ reduces mechanical wear, prevents particulate generation, and maintains consistent ejection force over ≥100,000 cycles—validated under accelerated life testing per ISO 8655-6.
