LongerPump BT100-3J Precision Peristaltic Pump with YZ1515X Pump Head

Overview

The LongerPump BT100-3J is a compact, CE-certified precision peristaltic pump engineered for reliable, low-maintenance fluid handling in analytical, biotechnology, and quality control laboratories. Based on the fundamental principle of peristalsis—where rollers compress flexible tubing to generate positive displacement—the BT100-3J delivers pulse-free, contamination-free flow without valves or seals contacting the fluid path. Its modular architecture supports interchangeable pump heads—including the YZ1515X—enabling seamless adaptation across diverse flow requirements and tubing specifications. Designed for integration into automated systems or standalone benchtop operation, the BT100-3J operates within a wide speed range (0.1–100 rpm) with 0.1 rpm resolution, ensuring precise volumetric delivery from nanoliter-scale dosing to high-throughput transfer at up to 380 mL/min (single-channel, with YZ1515X and compatible 13–25# tubing). The unit’s robust aluminum chassis, thermally stable motor drive, and low-noise operation make it suitable for continuous use in ISO Class 5–8 cleanrooms and GLP-compliant environments.

Key Features

• Three-digit LED speed display with intuitive membrane keypad interface for real-time manual adjustment
• Power-loss memory function: automatically resumes pre-interruption speed, direction, and operational state upon re-energization
• Dual-mode control architecture: local keypad + analog/RS485 remote interface (0–5 V, 0–10 V, 4–20 mA, 0–10 kHz input options)
• Full-speed override button for rapid priming, filling, or emptying without parameter reconfiguration
• Reversible rotation with smooth directional transition—critical for bidirectional fluid transfer and system purge protocols
• IP31-rated enclosure provides protection against vertically falling drips and solid objects >2.5 mm, meeting standard lab environmental requirements
• Low power consumption (30 W max) and wide-input AC supply (90–260 V) ensure global compatibility and stable performance under voltage fluctuation

Sample Compatibility & Compliance

The BT100-3J accommodates a broad spectrum of silicone, Viton®, and Tygon® tubing sizes—from inner diameters of ≤1.6 mm (e.g., 13#, 14#) up to 3.2 mm (e.g., 25#, 27#)—supporting flow rates scalable from 0.002 mL/min to 380 mL/min depending on pump head selection and tubing wall thickness. When equipped with the YZ1515X head and 16# or 25# tubing, the pump achieves optimal linearity and repeatability (<±0.5% CV over 24 h, per internal validation under ISO 5725-2 conditions). All electrical design and EMC behavior comply with EN 61326-1 (laboratory equipment) and EN 61000-6-3 (emission standards). CE marking confirms conformity with the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not rated for outdoor or hazardous area deployment, its construction meets typical institutional biosafety level 1–2 (BSL-1/2) facility requirements.

Software & Data Management

The BT100-3J features an RS485 serial interface compliant with Modbus RTU protocol, enabling native integration with LabVIEW, MATLAB, Python-based SCADA systems, or LIMS platforms via standard industrial gateways. Firmware supports ASCII command sets for programmable start/stop, direction toggle, speed ramping, and status polling (e.g., “RUN?”, “SPD?”, “DIR?”). Audit-ready operation is facilitated through external logging of control signals and timestamps—fully compatible with FDA 21 CFR Part 11-compliant data acquisition workflows when paired with validated host software. No proprietary drivers or cloud dependencies are required; configuration remains fully deterministic and traceable at the hardware layer.

Applications

• Automated sample introduction in HPLC, IC, and flow-injection analysis (FIA) systems
• Cell culture media perfusion and feeding in bioreactor auxiliary loops
• Calibration standard delivery in environmental water testing (EPA Method 300.0, ISO 15586)
• Reagent dispensing for ELISA, PCR setup, and microplate washing stations
• Continuous pH or conductivity probe calibration using standardized buffer streams
• In-line filtration monitoring where flow consistency directly impacts pressure differential interpretation

FAQ

What tubing sizes are supported with the YZ1515X pump head?
The YZ1515X head is optimized for tubing sizes 13#, 14#, 16#, 17#, 18#, 19#, and 25#, with recommended wall thicknesses of 0.8–1.0 mm and maximum ID ≤3.17 mm.
Does the BT100-3J support analog speed control with 4–20 mA input?
Yes—4–20 mA, 0–5 V, 0–10 V, and 0–10 kHz inputs are all natively supported for proportional speed regulation without additional signal conditioning.
Is firmware update capability available?
Firmware updates are performed via RS485 using vendor-provided utility software; version history and release notes are documented per IEC 62304 Class B software lifecycle requirements.
Can the pump be used in GMP-regulated pharmaceutical manufacturing?
While the BT100-3J itself is not 21 CFR Part 11–validated out-of-the-box, its deterministic control interface, audit-trail-capable communication, and CE/EMC compliance allow qualification per Annex 11 and WHO TRS 937 when integrated into a validated system architecture.
What is the expected service life of the motor under continuous operation?
Rated for ≥10,000 hours MTBF at 25 °C ambient and 60% load; roller compression force is factory-calibrated and non-adjustable to maintain tubing fatigue consistency across maintenance intervals.
