Longer L100-1F Intelligent Touchscreen Peristaltic Pump

Overview

The Longer L100-1F Intelligent Touchscreen Peristaltic Pump is an engineered solution for precise, repeatable, and programmable fluid handling in regulated laboratory, pharmaceutical, and industrial process environments. Based on the peristaltic principle—where rollers compress a flexible tubing against a curved housing to generate positive displacement—the L100-1F delivers contamination-free, pulse-dampened flow without valve or seal wear. Its design eliminates fluid contact with pump mechanics, ensuring integrity of shear-sensitive, corrosive, or sterile media. The system supports volumetric accuracy through factory-calibrated speed-to-flow mapping and optional user-initiated calibration routines, making it suitable for applications requiring traceable volumetric delivery under GLP or GMP-aligned workflows.

Key Features

• 7-inch full-color industrial touchscreen with intuitive graphical interface—enables real-time monitoring of speed, direction, elapsed time, and active program state
• Auto-recognition of pump head and tubing models via NFC-compatible identification tags (compatible with designated Longer pump heads and certified tubing sets)
• Programmable multi-step protocols: up to 7 user-saved schemes, each supporting up to 10 sequential steps with independent parameter assignment (speed, duration, direction, acceleration profile)
• Comprehensive motion control architecture: 9 built-in motion modules including constant-speed, linear ramp, sinusoidal oscillation, and volumetric dispensing modes
• Flexible logic sequencing: 8 programmable logic elements—including conditional triggers, time-based delays, status outputs, loop iterations, and external-event interrupts—enabling complex automation sequences
• Multi-modal control integration: native support for front-panel touch, footswitch activation, 0–5 V / 0–10 V analog input, and Modbus RTU serial communication over RS-485 (DB9) or TTL-level UART (RJ11)
• Modbus RTU protocol implementation compliant with standard register mapping, enabling seamless integration into SCADA, PLC, or LIMS platforms with configurable baud rates (1200–38400 bps)
• Calibration utility allowing users to input measured dispensed volume and automatically adjust internal flow-rate coefficients for improved long-term accuracy

Sample Compatibility & Compliance

The L100-1F accommodates a wide range of tubing materials—including silicone, Viton®, Tygon®, and PharMed® BPT—across inner diameters from 0.5 mm to 6.4 mm, enabling flow rate scalability from microliter-per-minute to 500 mL/min. Pump heads are mechanically interchangeable and validated for specific tubing sizes to maintain consistent occlusion and roller compression geometry. While the base unit does not carry CE marking by default, CE-compliant variants (L100-1FS) are available upon explicit order specification and include documented conformity with EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions). The device meets general electrical safety requirements per IEC 61010-1 for laboratory equipment and supports audit-ready operation when used with version-controlled parameter schemes and timestamped calibration logs.

Software & Data Management

No proprietary PC software is required for basic operation; all configuration, execution, and diagnostics occur locally via the embedded HMI. However, the Modbus RTU interface enables bidirectional data exchange with external supervisory systems. Register maps expose real-time operational states (e.g., running/stopped, forward/reverse, current speed), fault codes, and user-programmed scheme identifiers. For laboratories operating under 21 CFR Part 11 requirements, external systems may implement electronic signatures, audit trails, and role-based access control around commands issued via Modbus—though native electronic signature functionality is not embedded in the pump firmware. Language selection (English/Chinese) is configurable at startup and persists across power cycles.

Applications

The L100-1F serves critical roles in analytical sample introduction (e.g., HPLC mobile phase delivery, ICP-MS nebulizer feed), bioprocess media transfer (cell culture perfusion, buffer exchange), pharmaceutical formulation (dosing of APIs into dissolution vessels), and environmental testing (sequential reagent addition in automated wet-chemistry analyzers). Its programmable dispensing modules support gravimetric validation studies, while logic-triggered pauses and event-driven jumps enable synchronization with spectrophotometric detection windows or fraction collector actuation. In QC/QA labs, its reproducible flow profiles support method transfer between instruments and facilitate SOP-driven calibration verification per ISO/IEC 17025 guidelines.

FAQ

Does the L100-1F support automatic pump head and tubing identification?
Yes—when used with NFC-enabled pump heads and tubing assemblies (e.g., YZ15, DT14, or WG series), the system reads model-specific parameters from embedded tags near the handle, eliminating manual input errors and ensuring correct flow coefficient application.
Can the pump be integrated into a PLC-controlled production line?
Yes—via Modbus RTU over RS-485 (DB9) or TTL-level serial (RJ11), with full read/write access to operational registers, status flags, and scheme selection commands.
Is CE certification available for this model?
CE-marked versions (designated L100-1FS) are available upon request and include technical documentation aligned with EU Machinery and EMC Directives.
What is the maximum number of steps supported in a single program?
Each saved scheme supports up to 10 discrete steps, with independent speed, duration, direction, and motion profile settings per step.
How is flow accuracy maintained over time?
Users may perform periodic volumetric calibration by dispensing into a precision balance and entering the measured mass; the firmware recalculates and stores updated flow coefficients based on fluid density and tubing characteristics.
