Rainin Pipet-Lite XLS+ Single-Channel Manual Pipette with Conical Tip Holder

Overview

The Rainin Pipet-Lite XLS+ Single-Channel Manual Pipette with Conical Tip Holder is an ergonomically engineered liquid handling instrument designed for high-precision, low-volume manual pipetting in regulated and research-intensive laboratory environments. Unlike LTS™ (Low-Torque Sealing) systems—standard across most Rainin XLS+ models—this variant features a conical tip interface compatible with legacy or non-LTS-certified consumables, offering flexibility in tip sourcing without compromising mechanical integrity or volumetric accuracy. The device operates on a precision-machined air displacement principle, where piston movement within a sealed chamber generates controlled aspiration and dispensing of liquids. Its core architecture integrates patented magnetic-assist™ technology to reduce actuation force by up to 50% compared to conventional manual pipettes, significantly lowering biomechanical load during repetitive operations. Designed for daily use in QC labs, clinical diagnostics, genomics workflows, and GLP-compliant assay development, the SL-2XLS+ delivers traceable performance across its calibrated range of 0.1–2 µL.

Key Features

• Ergonomic conical tip holder compatible with standard conical (non-LTS) pipette tips—enabling seamless integration with existing tip inventories and third-party consumables.
• Magnetic-assist™ piston mechanism minimizes thumb force required for plunger actuation, reducing cumulative strain and supporting compliance with ISO 9241-5 and ANSI/HFES 100 human factors standards.
• Patented smooth-seal polymer piston seal and low-friction O-ring system ensure consistent vapor-tight sealing across repeated cycles, critical for volatile or viscous samples.
• Tool-free volume adjustment with tactile feedback dial and anti-slip knurled ring—designed for glove-compatible operation and resistance to accidental volume drift.
• Integrated RFID chip (ISO 15693 compliant) stores unique serial number, calibration history, service logs, and user-defined metadata—accessible via Rainin ProFlow™ RFID reader and PipetteTrack™ software.
• Autoclavable upper body (excluding electronics and RFID module); full chemical resistance to 70% ethanol, isopropanol, and dilute acids/bases per manufacturer specifications.

Sample Compatibility & Compliance

The SL-2XLS+ supports accurate handling of aqueous buffers, cell suspensions, serum, DNA/RNA solutions, and low-viscosity organic solvents within its specified volume range. It is validated for use with Class A and Class B pipette tips meeting ISO 8655-2 tolerances. The device conforms to ISO 8655-1 (general requirements), ISO 8655-5 (testing methods), and EN ISO/IEC 17025 for accredited calibration laboratories. Its embedded RFID functionality supports 21 CFR Part 11-compliant audit trails when paired with validated software, making it suitable for FDA-regulated environments including pharmaceutical QC, clinical testing, and contract research organizations operating under GLP or GMP frameworks.

Software & Data Management

Calibration data, usage frequency, maintenance records, and operator assignments are stored directly on the pipette’s RFID tag. When interfaced with the Rainin ProFlow™ desktop reader and PipetteTrack™ v3.2+ software (Windows 10/11, 64-bit), users can generate automated calibration reminders, export CSV/Excel reports for internal audits, and synchronize instrument status across multi-site lab inventories. All RFID transactions are timestamped and digitally signed, fulfilling ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate) data integrity requirements. Software validation packages—including IQ/OQ documentation and risk assessments—are available upon request for regulated deployments.

Applications

• High-sensitivity qPCR and digital PCR setup requiring sub-microliter precision.
• Microfluidic device loading and nanoliter-scale reagent dispensing in assay development.
• Cell-based assays involving small-volume cytokine or inhibitor titrations.
• Reference standard preparation in metrology labs adhering to ISO/IEC 17025.
• Teaching laboratories emphasizing ergonomic best practices and traceable technique training.
• Regulatory submissions where documented pipette performance history is mandatory (e.g., ICH M4, USP ).

FAQ

Is the conical tip holder interchangeable with LTS tips?
No—the SL-2XLS+ uses a dedicated conical interface and is not mechanically or dimensionally compatible with LTS tips. Attempting to mount LTS tips may result in poor sealing or inconsistent delivery.
Can this pipette be calibrated in-house using standard gravimetric methods?
Yes. It supports ISO 8655-6-compliant gravimetric calibration at accredited facilities or qualified internal labs equipped with Class I analytical balances and climate-controlled weighing chambers.
Does the RFID chip require battery replacement?
No. The RFID tag is passive (powered wirelessly by the reader) and has no internal power source—ensuring indefinite operational lifespan without maintenance.
What is the recommended recalibration interval?
Per ISO 8655-5 and industry best practice, recalibration is advised every 3–6 months for routine use, or after 10,000 cycles—whichever occurs first. Frequency may increase in high-humidity or corrosive environments.
Is technical support available for international customers?
Yes. Rainin provides multilingual application engineering support, remote calibration assistance, and certified service centers across EMEA, APAC, and the Americas—fully documented under ISO 9001 quality management systems.
