Longer L600-1F Intelligent Touchscreen Peristaltic Pump

Overview

The Longer L600-1F Intelligent Touchscreen Peristaltic Pump is an industrial-grade, microprocessor-controlled peristaltic pump engineered for precision fluid handling in regulated laboratory, pharmaceutical manufacturing, and pilot-scale process environments. Based on the fundamental principle of peristalsis—where rollers compress a flexible tubing segment against a rigid housing to generate positive displacement—the L600-1F delivers pulse-free, contamination-free, and shear-sensitive fluid transfer without valve or seal contact. Its design eliminates fluid-path wetted parts beyond the tubing itself, ensuring compliance with Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) requirements where material compatibility and cleanability are critical. Unlike fixed-speed or analog-controlled pumps, the L600-1F integrates real-time motor feedback, closed-loop speed regulation, and automatic pump head/tubing recognition to maintain volumetric accuracy across variable backpressure conditions and extended operation cycles.

Key Features

• Automatic pump head and tubing identification via NFC-enabled recognition zone—eliminates manual model entry errors and ensures correct flow calibration parameters are applied at startup.
• 7-inch full-color industrial TFT touchscreen with intuitive graphical interface supporting multi-language operation (English/Chinese), real-time status visualization, and drag-and-drop workflow configuration.
• Advanced programmable architecture: stores up to 7 user-defined parameter schemes, each supporting up to 10 sequential steps with independent speed, direction, duration, and logic triggers.
• Nine motion control modules: constant speed, linear acceleration/deceleration, stepwise ramping, sinusoidal modulation, uniform/incremental/decremental dispensing—enabling precise delivery profiles for gradient elution, cell culture media feeding, or reagent dosing.
• Eight logical control modules: direction switching, time-delayed execution, event-based triggering (e.g., sensor input), status output signaling, pause/resume, conditional jump, loop iteration, and emergency stop—facilitating integration into automated workflows.
• Multi-modal control support: local touchscreen, footswitch (optional), 0–5 V / 0–10 V analog input, digital I/O (RJ11), serial communication (DB9 RS-485), and USB host/device connectivity.
• Modbus RTU protocol implementation compliant with industry-standard SCADA and PLC integration frameworks; configurable baud rates (1200–38400 bps) and CRC error checking ensure robust data exchange.

Sample Compatibility & Compliance

The L600-1F accommodates a broad range of tubing materials—including silicone, Viton®, Tygon®, and Pharmapure®—with inner diameters from 0.5 mm to 13 mm, enabling flow rates from sub-mL/min to 3000 mL/min depending on tubing selection and pump head configuration. All tubing paths comply with USP Class VI and FDA 21 CFR Part 11 readiness guidelines when paired with audit-trail-enabled software systems. While the base unit carries CE marking upon explicit request (to be specified at order entry), its electrical safety conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions). The IP31 enclosure rating provides protection against vertically falling drips and solid objects >2.5 mm, suitable for controlled indoor laboratory and cleanroom-adjacent environments (ISO Class 8 or lower).

Software & Data Management

The pump operates autonomously without external PC dependency but supports bidirectional data exchange via Modbus registers for real-time monitoring of rotational speed, direction, elapsed runtime, and fault codes (e.g., overload, stall, tubing fatigue warning). Calibration routines allow users to input measured dispensed volume over a defined interval, automatically adjusting internal flow factor tables to compensate for tubing elasticity, wear, or temperature-induced viscosity shifts. Audit-ready operation is supported through timestamped parameter change logs stored in non-volatile memory. When integrated into validated systems, the L600-1F’s deterministic behavior, repeatable start/stop timing (<±50 ms), and deterministic I/O response align with ALCOA+ principles for data integrity under GxP-regulated applications.

Applications

• Pharmaceutical: Aseptic buffer preparation, continuous chromatography feed, bioreactor perfusion, and formulation transfer under cGMP-compliant processes.
• Life Sciences: Automated cell culture media exchange, chemostat dilution control, and microfluidic device priming with low-shear pumping.
• Chemical & Materials R&D: Precise catalyst slurry metering, polymer solution dosing, and solvent recycling loops requiring chemical resistance and inert fluid paths.
• Food & Beverage QA/QC: Standardized sample introduction for HPLC or titration systems, where tubing-only wetted surfaces prevent cross-contamination.
• Environmental Testing: Continuous wastewater sampling, nutrient dosing in bioremediation reactors, and field-deployable peristaltic metering in mobile labs.

FAQ

Does the L600-1F support FDA 21 CFR Part 11 compliance?
The hardware provides foundational capabilities—including electronic signatures, audit trails, and role-based access control—when deployed with validated third-party SCADA or MES software. Longer does not supply Part 11–certified firmware out-of-the-box.
Can I use non-Longer branded tubing with automatic recognition?
No. Automatic identification requires NFC tags embedded in Longer-certified pump heads and tubing assemblies. Third-party tubing may be used manually but will bypass auto-calibration and model-specific flow compensation.
What is the maximum allowable backpressure for continuous operation?
Maximum sustainable backpressure depends on tubing ID, wall thickness, and material; typical limits range from 0.2 bar (for 13 mm ID silicone) to 2.5 bar (for 3.2 mm ID Viton®). Refer to Longer’s Tubing Performance Handbook for pressure vs. flow curves.
Is remote firmware update supported?
Firmware updates require local USB connection using Longer-provided utilities; over-the-air (OTA) updates are not implemented.
How is flow accuracy maintained over time?
Flow calibration is retained in non-volatile memory and can be re-validated periodically using gravimetric or volumetric measurement. Tubing fatigue compensation is not automated but can be addressed by scheduled recalibration or programmable flow factor adjustment within saved schemes.
