Longer L600-1FS Intelligent Touchscreen Peristaltic Pump

Overview

The Longer L600-1FS is an industrial-grade intelligent peristaltic pump engineered for high-precision, repeatable fluid handling in regulated and research-intensive environments. Based on the principle of positive displacement through occlusive rotor compression of flexible tubing, it delivers accurate volumetric flow without fluid contact with internal mechanical components—ensuring contamination-free transfer of sensitive, corrosive, or sterile media. Designed for integration into automated laboratory workflows, bioprocessing skids, and pharmaceutical manufacturing lines, the L600-1FS combines robust mechanical architecture with advanced digital control logic. Its bidirectional speed range (0.1–300 rpm), sub-microliter-per-minute resolution at low speeds, and wide dynamic flow span (0.15 µL/min to 3000 mL/min) make it suitable for both micro-scale reagent dosing and bulk liquid transfer applications. The pump complies with electromagnetic compatibility requirements exceeding IEC 61326-1 Class II thresholds, supporting stable operation in electrically noisy industrial settings.

Key Features

• Auto-recognition system for pump heads and tubing: RFID-based identification eliminates manual model entry errors and ensures correct flow calibration parameters are loaded automatically.
• 7-inch full-color TFT touchscreen (1024×600 resolution) with intuitive graphical interface—supports dual-language operation (English/Chinese) and real-time visualization of speed, direction, elapsed time, and remaining volume.
• Comprehensive programmability: Up to 7 user-defined parameter schemes, each supporting up to 10 sequential steps; schemes include naming capability for traceable workflow management.
• Nine operational modules: Constant speed, linear acceleration/deceleration, stepwise ramping, sinusoidal modulation, uniform distribution, incremental/decremental dispensing.
• Eight logical control modules: Direction reversal, time delay, event-triggered execution, status output signaling, pause/resume, conditional jump, loop iteration, and emergency stop—enabling deterministic multi-stage fluid protocols.
• Multi-mode control architecture: Native support for touch, footswitch, analog voltage/current signals (0–5 V, 0–10 V, 4–20 mA), frequency input (0–10 kHz), and Modbus RTU communication over USB or RS485 (RJ11).
• Integrated calibration utility: Users input measured dispensed volume; the system calculates and applies correction factors to flow rate and total volume counters—critical for GLP/GMP-aligned process validation.

Sample Compatibility & Compliance

The L600-1FS accommodates a broad range of peristaltic pump tubing materials—including silicone, Viton®, Tygon®, and PharmPure®—across inner diameters from 0.1 mm to 13 mm, enabling compatibility with ISO 8536-4 compliant IV sets, USP Class VI-certified bioprocess tubing, and FDA-listed elastomers. While the base unit is manufactured in Hebei, China, CE-marked configurations are available upon explicit request and subject to harmonized conformity assessment under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). For regulated pharmaceutical use, the device supports audit-trail-ready operation when paired with validated SCADA or MES platforms via Modbus—facilitating alignment with FDA 21 CFR Part 11 data integrity requirements where electronic records and signatures are employed.

Software & Data Management

No proprietary PC software is required for basic operation; however, the pump’s native Modbus RTU implementation enables seamless integration with LabVIEW, MATLAB, Python (via PyModbus), or commercial SCADA systems. All programmable schemes, calibration offsets, and runtime logs are stored non-volatilely in onboard flash memory. Status outputs (e.g., “running”, “paused”, “direction change”) can be mapped to discrete TTL-level signals via DB9 pins for PLC synchronization. Time-stamped operational events—including start/stop timestamps, scheme invocation, and error codes—are accessible via serial query, supporting retrospective analysis during QA investigations. Firmware updates are delivered via USB mass storage mode, ensuring field-upgradability without service intervention.

Applications

• Pharmaceutical R&D: Precise buffer exchange in chromatography system priming, fraction collector triggering, and continuous perfusion bioreactor feed control.
• Diagnostic assay automation: Metered delivery of reagents, wash buffers, and conjugates in ELISA and lateral flow platforms.
• Chemical synthesis: Controlled addition of catalysts or monomers in exothermic reactions where heat-sensitive pumping is essential.
• Food & beverage QC labs: Consistent sample homogenization, dilution series preparation, and viscosity-standardized dispensing for texture analyzer calibration.
• Environmental testing: Automated leachate sampling, titrant delivery in potentiometric titrators, and peristaltic-driven filtration manifold control.

FAQ

Does the L600-1FS support FDA 21 CFR Part 11 compliance?
The pump itself does not embed electronic signature functionality, but its Modbus-enabled data logging, non-volatile parameter storage, and deterministic control behavior allow it to operate as a compliant component within a validated system architecture—provided the host software implements appropriate audit trails, role-based access, and electronic signature controls.

Can I use third-party tubing with the auto-recognition feature?
No. Auto-recognition relies on factory-programmed RFID tags embedded exclusively in Longer-branded pump heads and certified tubing assemblies. Generic tubing will require manual configuration and may compromise flow accuracy unless independently calibrated.

What is the maximum allowable backpressure for continuous operation?
The L600-1FS is rated for continuous operation at ≤2 bar (29 psi) with standard silicone tubing (ID 3.2 mm). Higher pressures require reinforced tubing and reduced speed to maintain tube life and positional repeatability.

Is firmware update capability available in the field?
Yes. Firmware updates are distributed as .bin files and applied via USB mass storage mode—no external programmer or service technician is required.

How is flow accuracy validated across the full range?
Accuracy is verified using gravimetric measurement per ISO 8570:2020 Annex B methodology: three independent 5-minute dispensing trials at 10%, 50%, and 90% of maximum rated flow, with results reported as mean ± standard deviation relative to theoretical volume.
