Longer L100-1FS Intelligent Touchscreen Peristaltic Pump

Overview

The Longer L100-1FS is an intelligent, microprocessor-controlled peristaltic pump engineered for precision fluid handling in regulated laboratory, pharmaceutical, and industrial process environments. It operates on the fundamental principle of peristalsis—using rotating rollers to compress flexible tubing, thereby generating positive displacement flow without fluid contact with mechanical components. This design ensures contamination-free transfer, chemical compatibility across a broad range of solvents and reagents, and maintenance of sterility in closed-loop systems. The L100-1FS integrates high-resolution speed control (0.1 rpm minimum increment), bi-directional operation, and real-time flow calibration capabilities—making it suitable for applications demanding reproducible volumetric delivery, such as reagent dosing, cell culture media perfusion, chromatography solvent delivery, and continuous sampling in online monitoring systems.

Key Features

• Auto-identification of pump heads and tubing via RFID/NFC tags mounted on compatible accessories—eliminates manual model entry errors and ensures accurate flow profile mapping.
• 7-inch true-color TFT LCD (1024 × 600 resolution) with intuitive graphical interface supporting dual-language (English/Chinese) operation and multi-touch gesture navigation.
• Advanced programmable architecture: up to 7 customizable parameter schemes, each supporting up to 10 sequential steps; schemes may be named alphanumerically for traceable recall.
• Nine configurable motion control modules: constant speed, linear acceleration/deceleration, stepwise ramping, sinusoidal modulation, uniform distribution, incremental/decremental dispensing.
• Eight logical control modules: direction switching, time delay, event-triggered execution, status output signaling, pause/resume, conditional jump, loop iteration, and termination—all combinable for complex multi-phase protocols.
• Multi-mode control interface: local touchscreen, footswitch, analog voltage/current signals (0–5 V, 0–10 V, 4–20 mA, 0–10 kHz), and digital communication via USB or RS-485 (RJ11 connector).
• Modbus RTU protocol compliance enables seamless integration into SCADA, PLC, and LIMS platforms; supports baud rates from 1200 to 38400 bps.
• Integrated backflow prevention: programmable retract angle and delay to minimize drip after dispensing—critical for low-viscosity aqueous solutions and sterile transfers.

Sample Compatibility & Compliance

The L100-1FS accommodates a wide selection of OEM-certified pump heads and chemically resistant tubing materials—including silicone, Viton®, Tygon®, and PharMed® BPT—enabling compatibility with aggressive solvents, biological buffers, and high-purity pharmaceutical formulations. Its flow range spans 0.15 µL/min to 500 mL/min, supporting both microfluidic precision and bulk transfer requirements. While the device meets CE marking requirements upon explicit request (subject to factory certification documentation), its electromagnetic compatibility (EMC) performance conforms to IEC 61326-1 Class B specifications, with immunity and emission levels exceeding EN 61000-4 series standards for industrial environments. For GxP-regulated use, audit trail functionality is enabled through external software logging; the pump itself supports timestamped parameter changes and state transitions when interfaced with compliant host systems adhering to FDA 21 CFR Part 11 principles.

Software & Data Management

No proprietary PC software is bundled, but the L100-1FS exposes all operational parameters—including speed, direction, elapsed time, total dispensed volume, and current phase status—via standardized Modbus registers. Third-party platforms (e.g., LabVIEW, MATLAB, Python-based control suites using PyModbus) can poll these registers at configurable intervals for real-time data acquisition and automated report generation. Internal non-volatile memory retains all saved schemes and calibration offsets across power cycles. USB connectivity permits firmware updates and configuration backup/restore operations. All parameter edits are logged with timestamps in external supervisory systems, satisfying basic GLP/GMP traceability needs when deployed within validated workflows.

Applications

• Pharmaceutical R&D: Accurate metering of APIs during formulation development and stability testing.
• Biotechnology labs: Continuous perfusion of bioreactors and automated feeding in single-use systems.
• Environmental analysis: On-line sampling and dilution in wastewater monitoring stations.
• Chemical synthesis: Controlled addition of catalysts or reagents in flow chemistry reactors.
• Food & beverage QC: Precise ingredient dosing in pilot-scale blending and homogenization lines.
• Academic research: Teaching instrument for fluid dynamics, pump mechanics, and automation logic design.

FAQ

Does the L100-1FS support FDA 21 CFR Part 11 compliance?
The pump itself does not provide electronic signature or built-in audit trail features. However, when integrated with validated third-party software that captures and signs all control commands and parameter changes, it can operate within Part 11–compliant workflows.
Can I calibrate flow rate directly on the device?
Yes—users may perform manual calibration by dispensing a known volume and entering the measured value; the system computes and applies a correction factor to subsequent flow calculations.
What tubing sizes are supported?
Tubing inner diameters from 0.1 mm to 6.4 mm are compatible, depending on selected pump head models (e.g., YZ15, YZ25, DG series). Full compatibility matrix is provided in the technical manual.
Is remote firmware update possible over RS-485?
Firmware updates require USB connection and dedicated utility software provided by LongerPump; RS-485 is reserved for runtime command/control only.
How is safety ensured during unattended operation?
The pump includes thermal overload protection, stall detection, and configurable timeout limits per program step. External interlocks (e.g., door switches, pressure sensors) can be wired to the status input terminals for emergency shutdown.
