Longer BT600-2J Precision Peristaltic Pump

Overview

The Longer BT600-2J Precision Peristaltic Pump is an engineered solution for accurate, contamination-free fluid handling in laboratory and light industrial environments. Based on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the BT600-2J eliminates fluid contact with pump internals, ensuring sample integrity and simplifying cleaning and maintenance. Designed for high reproducibility and long-term operational stability, it delivers a broad flow range of 0.07 to 3000 mL/min across multiple interchangeable pump heads, making it suitable for applications requiring both low-flow precision (e.g., reagent dosing, HPLC mobile phase delivery) and higher-volume transfer (e.g., buffer circulation, cell culture media feeding). Its robust architecture supports continuous operation under controlled ambient conditions (0–40 °C, <80% RH), and its IP31-rated enclosure provides basic protection against vertically falling drips and solid objects larger than 2.5 mm—appropriate for standard laboratory benchtop use.

Key Features

• Multi-pump-head compatibility: Supports YZ1515X, YZ2515X, YZII15, YZII25, and DG15-24 pump heads—enabling optimized flow performance across diverse tubing sizes (e.g., Norprene®, PharMed®, Tygon®) and chemical compatibility profiles.
• Wide dynamic range: Achieves fine-resolution flow control from 0.07 mL/min (with small-bore tubing and YZII15 head) up to 3000 mL/min (with large-bore tubing and YZII25 head), all within a single drive unit.
• Dual-mode operation: Local control via intuitive rotary knob and push-button interface; remote operation via analog voltage (0–5 V or 0–10 V), TTL-compatible pulse input (0–10 kHz), or industry-standard RS485 Modbus RTU protocol.
• Power-loss recovery: Built-in non-volatile memory retains last-used speed, direction, and operating mode—automatically restoring pre-interruption state upon power restoration.
• Full-speed override: Dedicated hardware button enables immediate maximum-speed operation for rapid system priming, line purging, or vessel filling—without altering stored parameters.
• Bidirectional rotation: Enables reversible flow for backflushing, recirculation loops, or dual-directional liquid handling protocols.

Sample Compatibility & Compliance

The BT600-2J is inherently chemically inert—fluid path is fully defined by user-selected tubing material, allowing seamless adaptation to aggressive solvents, biological buffers, acids, bases, or shear-sensitive biologics. Common tubing options include silicone (general purpose), Viton® (halogenated solvent resistance), and platinum-cured silicone (USP Class VI, FDA-compliant for pharmaceutical use). While the base unit does not carry CE marking by default, CE-compliant versions are available upon explicit request and subject to factory certification documentation. The device meets IEC 61000-6-3 (EMI emission) and IEC 61000-6-2 (immunity) requirements for laboratory equipment. It is intended for indoor use only and is not rated for outdoor, explosive, or sterile-process-critical environments without additional validation.

Software & Data Management

The BT600-2J operates as a standalone instrument but integrates seamlessly into automated workflows via its RS485 interface. When connected to a host PC or PLC, users can implement centralized control using Modbus RTU commands for real-time speed adjustment, direction toggling, start/stop sequencing, and status polling (e.g., running state, error flags). Optional companion devices—including the FK-1C dispensing controller—extend functionality to volumetric dispensing, multi-step batch filling, and time-based aliquoting. Audit trail generation and electronic record retention require integration with validated third-party SCADA or LIMS platforms compliant with 21 CFR Part 11 (for regulated labs), where user authentication, change logging, and electronic signatures may be implemented at the system level.

Applications

• Automated liquid handling in analytical chemistry labs (e.g., continuous-flow UV-Vis sample introduction, titration reagent delivery)
• Cell culture bioreactor feed and harvest systems requiring gentle, pulseless flow
• Pharmaceutical R&D: excipient metering, dissolution testing media circulation, and formulation blending
• Environmental testing: sequential extraction, leachate pumping, and calibration standard delivery
• Food & beverage QC: viscosity-adjusted syrup dosing, dairy product transfer, and flavor concentrate addition
• Integration into custom OEM instruments where compact, programmable, low-maintenance fluid transport is required

FAQ

Does the BT600-2J support GLP/GMP-compliant operation?
It can be deployed in GLP/GMP environments when integrated with validated software systems that provide audit trails, user access controls, and electronic signature capabilities—though the pump itself is not individually certified.
What tubing sizes are supported with each pump head?
YZII15 accommodates tubing IDs from 0.13 to 2.4 mm; YZ1515X supports 0.5 to 3.2 mm; YZII25 and YZ2515X accept IDs up to 6.4 mm. Exact flow rates depend on wall thickness, material compliance, and rotational speed.
Is firmware update capability available?
Firmware updates are performed via RS485 using Longer’s proprietary configuration utility—available under NDA for OEM partners and qualified end-users.
Can the pump be used with corrosive or high-temperature fluids?
Only through appropriate tubing selection (e.g., fluoropolymer-lined tubing for strong oxidizers; high-temp silicone for ≤120 °C intermittent service). The pump housing and drive mechanism are not designed for direct exposure to such media.
What is the expected service life of the motor and roller assembly?
Under typical laboratory usage (≤8 h/day, moderate load), the brushless DC motor and hardened steel roller train are rated for ≥10,000 hours of operation with periodic tubing replacement every 500–2000 hours depending on speed, pressure, and tubing type.
