Overview
The Rainin EA6-300XLS is an electronically actuated, 6-channel pipette engineered for high-throughput liquid handling in regulated and research-intensive laboratory environments. Unlike fixed-spacing multichannel pipettes, the EA6-300XLS features motorized, programmable inter-tip spacing adjustment—enabling seamless transfer of samples between heterogeneous vessel formats including 96-well plates, 384-well plates, PCR strips, microcentrifuge tubes, and conical vials. This capability eliminates manual repositioning, reduces repetitive motion, and cuts pipetting steps by up to 98% when bridging workflows across plate layouts with differing well geometries. Its core operation relies on precision stepper-motor-driven piston displacement and closed-loop feedback control, ensuring consistent aspiration and dispensing across all six channels. Designed and assembled in Switzerland, the EA6-300XLS conforms to ISO 8655-2:2022 for gravimetric performance verification and supports traceable calibration in accordance with metrological best practices.
Key Features
- Motorized adjustable tip spacing (range: 4.5 mm to 14.2 mm), programmable via intuitive joystick interface and graphical display
- Electronic volume selection with 0.2 µL resolution across 20–300 µL range; real-time volume confirmation on OLED screen
- LiteTouch System (LTS) tip ejection—reducing force required by >50% versus standard systems, minimizing operator fatigue and tip damage
- Onboard memory for up to 20 user-defined protocols, including repeat dispense, serial dilution, reverse pipetting, and multi-dispense modes
- Password-protected configuration settings—including volume limits, alarm thresholds, service reminders, and protocol editing rights—to support audit readiness
- Integrated battery management with USB-C charging and >12 hours of continuous operation per full charge
- Ergonomic, low-center-of-gravity housing with balanced weight distribution (168 g) and textured grip surface for prolonged use
Sample Compatibility & Compliance
The EA6-300XLS accommodates standard LTS-compatible pipette tips (including filtered and low-retention variants) and maintains volumetric accuracy across a wide range of liquid classes—including aqueous buffers, glycerol-containing solutions (up to 40% v/v), and viscous cell lysates—when used with appropriate technique and tip conditioning. Its firmware architecture supports configurable compliance logging: all parameter changes, protocol executions, and service events are timestamped and stored locally with optional export to CSV. The device meets essential requirements for GLP and GMP environments, including user access control, electronic signature support (via external integration), and adherence to FDA 21 CFR Part 11 principles when paired with validated LIMS or ELN platforms. Calibration certificates conform to ISO/IEC 17025-accredited procedures and include uncertainty budgets per ISO 8655-6.
Software & Data Management
While the EA6-300XLS operates autonomously without PC dependency, it supports bidirectional communication via USB-C for firmware updates, protocol synchronization, and audit log extraction. Rainin’s free Pipette+ desktop application enables centralized fleet management—allowing administrators to push standardized configurations, validate calibration status, and generate compliance reports aligned with internal SOPs or external inspection criteria (e.g., ISO 15189, CLIA). All protocol files are digitally signed to prevent unauthorized modification. Service alerts—such as recalibration due dates, battery health warnings, or mechanical wear indicators—are configurable and enforce preventive maintenance schedules compliant with ISO 13485 quality system requirements.
Applications
- High-efficiency plate-to-plate transfers in ELISA, qPCR setup, and cell-based assay workflows
- Parallel sample preparation for NGS library construction, including tagmentation and indexing steps
- Automated serial dilution series generation across variable well spacing (e.g., from master mix reservoirs to assay plates)
- Quality control testing in pharmaceutical manufacturing—where traceability, repeatability, and change control are mandatory
- Biobanking operations requiring precise aliquoting into cryovials and barcoded storage tubes with non-uniform spacing
- Academic core facilities supporting shared instrumentation with role-based access and usage tracking
FAQ
What spacing ranges does the EA6-300XLS support?
It adjusts automatically between 4.5 mm and 14.2 mm center-to-center tip distance, covering common formats from 96-well (9 mm) to 384-well (4.5 mm) and tube racks (9–14.2 mm).
Is LTS tip compatibility mandatory?
Yes—the EA6-300XLS is mechanically and functionally optimized exclusively for Rainin LTS tips; use of non-LTS tips voids calibration validity and may damage the ejection mechanism.
Can the device be calibrated in-house?
Yes—users may perform routine performance checks using gravimetric methods per ISO 8655-6; however, full recalibration requires Rainin-certified service technicians or authorized calibration laboratories.
Does it support electronic signatures for regulated workflows?
The device itself does not host digital signature functionality, but its logged events and exported data are structured to integrate with validated third-party ELN/LIMS systems that provide 21 CFR Part 11-compliant electronic signature capabilities.
How is battery life monitored?
Remaining capacity is displayed as a percentage on the OLED screen; low-battery warnings activate at 15%, and the system enters sleep mode at 5% to preserve configuration memory.
