Overview
The LongerPump L100-1FS, L300-1FS, and L600-1FS series are high-precision, microprocessor-controlled peristaltic pumps engineered for repeatable, contamination-free fluid handling in regulated laboratory, pharmaceutical manufacturing, and industrial process environments. Based on the fundamental principle of positive displacement via roller compression of elastomeric tubing, these pumps eliminate fluid contact with internal mechanical components—ensuring sterility, chemical compatibility, and maintenance-free operation across diverse media including aggressive solvents, viscous suspensions, and shear-sensitive biologics. Each model features a modular architecture supporting interchangeable pump heads and tubing configurations, enabling seamless adaptation from nanoliter-scale analytical dosing to liter-per-minute transfer applications. Designed for integration into automated workflows, the series complies with core instrumentation design expectations under ISO/IEC 17025, USP , and FDA 21 CFR Part 11 when deployed with audit-trail-enabled software and validated operational protocols.
Key Features
- Auto-recognition system for pump heads and tubing: NFC-based identification at the handle-mounted sensor eliminates manual configuration errors and ensures accurate flow calibration per tubing geometry and wall thickness.
- 7-inch true-color TFT LCD touchscreen (1024 × 600 resolution) with intuitive graphical interface supporting multi-language operation (English/Chinese selectable).
- Advanced programmability: Up to 7 customizable parameter schemes, each configurable with up to 10 sequential steps; supports variable speed profiles, direction toggling, pause/resume logic, and conditional branching.
- Nine motion control modules: Constant speed, linear acceleration/deceleration, stepwise ramping, sinusoidal modulation, uniform distribution, incremental/decremental dispensing.
- Eight logic control modules: Direction switching, time delay, event-triggered execution, status output signaling, loop iteration, jump-to-step, suspend/resume, and termination.
- Multi-mode control architecture: Local touchscreen, footswitch actuation, analog voltage/current input (0–5 V, 0–10 V, 4–20 mA, 0–10 kHz), digital TTL/relay triggers, and serial communication (Modbus RTU over USB or RS-485).
- Integrated calibration routine: Users input measured dispensed volume; the firmware automatically adjusts volumetric output compensation without requiring external flow meters.
- Dedicated functions for precision dispensing: Backflow compensation (retract angle + delay), timed interval dispensing (0.5 s–9000 s), repeat count (1–99999 or infinite), and scheduled start time.
Sample Compatibility & Compliance
These peristaltic pumps accommodate a wide range of tubing materials—including silicone, Viton®, Tygon®, C-Flex®, and PharMed® BPT—enabling compatibility with aqueous buffers, organic solvents, acids, bases, and cell culture media. Tubing inner diameters from 0.1 mm to 9.5 mm are supported across optional pump heads (e.g., YZ15, YZ25, DG series). The IP31-rated enclosure provides protection against vertically falling droplets and solid objects >2.5 mm, suitable for cleanroom-adjacent benchtop use (ISO Class 7/8) and non-sterile GMP production areas. Electromagnetic compatibility meets IEC 61326-1 Class II standards for laboratory instrumentation. When operated with validated firmware and documented SOPs, the system supports GLP and GMP data integrity requirements, including electronic signature readiness and traceable parameter versioning.
Software & Data Management
While the pump operates autonomously via its embedded controller, full remote supervision and data logging are achievable through Modbus RTU communication (baud rates: 1200–38400 bps) over USB or RS-485 (RJ11). Integration with SCADA systems, LIMS, or custom LabVIEW/Python applications is facilitated by open protocol documentation. All parameter schemes—including speed profiles, dispensing volumes, timing sequences, and logic conditions—are stored non-volatilely with timestamped revision history. Status outputs (running/stopped, forward/reverse, phase-specific flags) can be routed to PLCs or alarm systems via isolated digital I/O lines. For regulatory submissions, raw operational logs—including start/stop timestamps, actual vs. target flow rates, and error codes—can be exported in CSV format following defined audit trail conventions.
Applications
- Pharmaceutical R&D: Accurate reagent dosing in high-throughput screening, buffer exchange in protein purification, and continuous feed in bioreactor perfusion systems.
- Quality control laboratories: Automated sample dilution, standard addition workflows, and column equilibration in HPLC/GC sample introduction.
- Chemical synthesis: Controlled addition of catalysts or monomers in exothermic reactions; inert atmosphere-compatible solvent transfer.
- Food & beverage testing: Precise delivery of preservatives or flavorings during sensory panel preparation; viscosity-independent metering of particulate-laden juices.
- Environmental analysis: On-site field sampling with portable power options; low-pulsation pumping for membrane filtration and TOC analyzer feed.
- Academic research: Closed-loop infusion in animal pharmacokinetic studies; synchronized multi-pump sequencing in microfluidic platform development.
FAQ
Does the auto-tubing recognition require proprietary consumables?
No—the NFC tags are embedded in standard LongerPump-certified pump heads and tubing assemblies; third-party tubing may be used, but will not benefit from automatic parameter loading or calibrated flow compensation.
Can the pump maintain consistent flow across varying backpressures?
Peristaltic pumps inherently exhibit flow rate stability under moderate pressure differentials (< 2 bar); however, significant downstream resistance may reduce effective flow. For high-pressure applications, consult tubing burst ratings and consider pulsation dampeners.
Is Modbus communication compatible with common industrial PLCs?
Yes—Modbus RTU over RS-485 (RJ11) or USB virtual COM port is fully interoperable with Allen-Bradley, Siemens S7, Mitsubishi FX, and Omron CJ/NJ series controllers using standard function codes (03h, 06h, 10h).
How is flow accuracy verified and maintained over time?
Users perform periodic gravimetric or volumetric calibration using certified reference standards; the firmware applies linear compensation factors to subsequent runs. No mechanical recalibration is required.
What safety provisions exist for unattended operation?
The pump includes thermal overload protection, stall detection, and configurable timeout limits per program step. External interlocks can be wired via the DB9 I/O port for emergency shutdown linkage.
