Overview
The LongerPump TS-2A/L0107-2A is a precision-engineered, four-channel independent-control syringe pump designed for demanding microfluidic applications in life science laboratories. Operating on the principle of linear stepper motor-driven plunger displacement, it delivers highly reproducible volumetric delivery and aspiration with deterministic control over fluid movement at nanoliter-to-milliliter scales. Its modular architecture—comprising a centralized controller and detachable actuator units—enables flexible integration into complex experimental setups, including micromanipulation rigs, stereotaxic frames, patch-clamp systems, and microinjection platforms. The pump supports both push and pull modes per channel, allowing bidirectional fluid handling without hardware reconfiguration. With a maximum stroke of 70 mm and sub-micrometer positional resolution (0.165 µm), the TS-2A achieves exceptional repeatability across extended operational cycles, making it suitable for long-duration perfusion, sequential dosing, and multi-step assay automation.
Key Features
- Four independently programmable channels with fully decoupled parameter control—each channel can operate in injection, withdrawal, injection-then-withdrawal, withdrawal-then-injection, or continuous cycling mode.
- High-resolution linear motion control: 0.165 µm stroke resolution and linear speed range from 7.94 µm/min to 79.4 mm/min—enabling precise adaptation to syringes ranging from 1 µL glass capillaries to 100 mL industrial barrels.
- Integrated syringe database covering major global manufacturers (e.g., Hamilton, BD, SGE, Ito) with support for up to four user-defined syringe inner diameters per channel—ensuring accurate flow calculation based on cross-sectional area.
- Dual OC-gate status outputs per channel (start/stop + direction), plus three TTL-level external trigger inputs (start, fast-forward, fast-reverse)—facilitating synchronization with electrophysiology recorders, fluorescence imaging systems, or PLC-based lab automation.
- RS485 serial interface compliant with Modbus RTU protocol for reliable multi-drop communication and remote orchestration via LabVIEW, Python, MATLAB, or custom SCADA environments.
- Robust mechanical design with >20 N rated linear thrust and integrated stall detection—automatically halts operation and triggers audible alarm upon occlusion or mechanical blockage.
- Power-loss recovery function: retains all runtime parameters and allows resumption from pre-interruption state upon power restoration, supporting GLP-aligned unattended overnight protocols.
Sample Compatibility & Compliance
The TS-2A accommodates standard Luer-lock and cemented-tip syringes from 1 µL to 100 mL capacity, with validated compatibility across borosilicate glass, polypropylene, and stainless-steel barrels. Its open syringe calibration framework supports traceable volume verification per ISO 8655-3 and ASTM E2713 guidelines. While not certified as IVD or medical device under FDA 21 CFR Part 820, the system meets general laboratory equipment requirements per IEC 61010-1 for electrical safety and EMC immunity. Its parameter logging, timestamped event records, and non-volatile configuration storage align with basic data integrity expectations for QC/QA workflows under ISO/IEC 17025 and internal SOPs. Firmware supports audit-trail-enabling configurations when deployed with compliant host software.
Software & Data Management
The pump operates autonomously using its embedded firmware but is fully compatible with LongerPump’s PC-based Longerkonfig software (Windows/macOS), which provides graphical workflow builder, real-time monitoring dashboards, and CSV export of time-stamped flow, volume, and status logs. All parameter changes—including volume, timing intervals, cycle counts, and delay offsets—are stored with metadata (user ID, timestamp, channel ID). When integrated into networked lab infrastructures, the RS485 interface enables integration with LIMS or ELN systems via middleware adapters. No proprietary cloud services or mandatory online activation are required—data remains local by default, satisfying institutional data sovereignty policies.
Applications
- Neuroscience: Stereotactic microinjection of viral vectors, tracers, or pharmacological agents into rodent brain regions with inter-channel temporal offset for multi-site delivery.
- Electrophysiology: Continuous perfusion of recording chambers with drug cocktails or ion substitution solutions while maintaining stable osmolarity and temperature.
- Single-cell analysis: Controlled loading of reagents into microfluidic chips for droplet generation, cell encapsulation, or on-chip lysis.
- Drug discovery: Automated multi-concentration dose-response assays using sequential aspiration/injection across four parallel wells or tissue slices.
- Material science: Precise deposition of polymer precursors or nanomaterial suspensions during 3D bioprinting or thin-film fabrication.
FAQ
What syringe sizes and materials are supported?
Standard Luer-lock syringes from 1 µL (glass capillaries) to 100 mL (polypropylene or stainless steel) are supported. Custom inner diameter entries allow calibration for non-standard or tapered barrels.
Can all four channels run different protocols simultaneously?
Yes—each channel maintains independent parameter sets for volume, speed, timing, and mode. One channel’s settings can be copied to others, but full autonomy is preserved.
Is flow rate accuracy traceable to national standards?
While the pump itself is not NIST-traceably calibrated out-of-box, its 0.5% stroke accuracy (≥30% max stroke) and built-in volumetric correction routine enable users to perform in-house gravimetric or spectrophotometric validation per ISO 8655-3.
Does the system support regulatory-compliant electronic records?
The pump stores all operational parameters and events locally. When paired with validated third-party software that implements 21 CFR Part 11 controls (e.g., audit trails, electronic signatures), it can support regulated workflows.
How is mechanical overload or tubing occlusion detected?
Stall detection is implemented via real-time current monitoring of the stepper motor driver. Upon sustained torque limit exceedance (>20 N threshold), the affected channel halts, emits an audible alert, and reports fault status via OC output and display.
