ISMATEC REGLO QUICK™ ISM897 Peristaltic Pump

Overview

The ISMATEC REGLO QUICK™ ISM897 is a precision-engineered, single-channel peristaltic pump designed for reliable, pulse-free fluid transfer in analytical laboratories, bioprocessing workflows, and quality control environments. Operating on the principle of positive displacement via occlusion—where rotating rollers compress flexible tubing against a rigid housing—the ISM897 delivers high reproducibility and minimal shear stress to sensitive fluids such as cell suspensions, enzymes, or particulate-laden reagents. Its 4-roller head architecture ensures smoother flow profiles and reduced pulsation compared to standard 2-roller configurations, supporting applications requiring stable volumetric delivery over extended operation cycles. The pump is engineered for integration into automated systems and standalone benchtop use, with compatibility across widely available, industry-standard tubing materials including Tygon® ST-Wall, Norprene®, and peroxide-cured silicone—ensuring chemical resistance and compliance with USP Class VI and FDA-compliant material specifications.

Key Features

• Single-channel peristaltic pump with 4-roller head for enhanced flow stability and reduced pulsation amplitude
• Adjustable speed range from 3.2 to 160 rpm, enabling precise control over flow rates from 2.1 to 230 mL/min depending on tubing ID and wall thickness
• Quick-access tube bed design allows full pump tube replacement in under 30 seconds—minimizing system downtime during routine maintenance or method changes
• Compact footprint (W × D × H: 145 × 170 × 130 mm) optimized for space-constrained laboratory benches or integrated instrument enclosures
• Analog input (0–10 V or 4–20 mA) and analog output (0–10 V) support real-time remote speed control and process monitoring; optional digital input (TTL/RS-485) enables synchronization with PLCs or LIMS platforms
• Front-panel LED display with intuitive rotary encoder interface provides immediate visual feedback of setpoint, actual speed, and operational status

Sample Compatibility & Compliance

The ISM897 is compatible with a broad range of elastomeric tubing certified for laboratory and industrial use. Recommended tubing includes Tygon® ST-Wall (ID 1.6–4.8 mm), Norprene® A-60-F (for aggressive solvents), and peroxide-cured silicone (for high-purity aqueous applications). All recommended tubing meets ISO 10993-5 cytotoxicity requirements and complies with USP Class VI biological reactivity standards. While the pump itself does not carry CE or UL certification out-of-the-box, its electrical architecture adheres to IEC 61010-1 safety principles for laboratory equipment. When operated with validated tubing and documented SOPs, the ISM897 supports GLP and GMP-aligned workflows where traceability, repeatability, and material compatibility are critical—particularly in pharmaceutical QC, environmental sample preparation, and continuous-flow synthesis setups.

Software & Data Management

The ISM897 operates autonomously without proprietary software dependency, yet integrates seamlessly into data-rich environments through standardized analog and optional digital interfaces. Analog output signals can be logged directly into SCADA systems, LabVIEW, or custom Python-based acquisition scripts using USB-to-analog DAQ modules. For audit-trail compliance in regulated settings, users may configure external controllers to record timestamps, speed setpoints, and runtime duration—supporting alignment with FDA 21 CFR Part 11 requirements when paired with electronic signature-capable platforms. Firmware updates are performed via physical dip-switch configuration; no cloud connectivity or vendor-hosted services are involved—ensuring full data sovereignty and network isolation.

Applications

• Automated reagent dispensing in ICP-MS, AA, and UV-Vis sample introduction systems
• Continuous feed of culture media or harvest streams in small-scale bioreactors and perfusion systems
• Controlled eluent delivery in preparative chromatography and inline filtration validation studies
• Calibration standard delivery for flow meter verification per ISO 4064-2
• Environmental water sampling—low-shear transfer of turbid or suspended-solid-containing samples without clogging risk
• Integration into ASTM D5116-compliant VOC emission testing chambers for controlled purge gas delivery

FAQ

What tubing sizes are supported by the ISM897?
The pump accommodates tubing with internal diameters from 1.6 mm to 4.8 mm, including Tygon® R-3603 (1.6 mm ID), R-3607 (1.6 mm ID, thicker wall), and SC0379 (1.6 mm ID, high-pressure variant). Flow rate tables are provided in the user manual for each tubing type.
Can the ISM897 be used in sterile or cleanroom environments?
Yes—when paired with gamma-sterilizable tubing (e.g., selected Norprene® or silicone variants) and housed in an ISO Class 5 laminar flow cabinet, the ISM897 supports aseptic liquid handling protocols. No internal lubricants or vented components compromise containment integrity.
Is speed calibration traceable to NIST standards?
While the pump’s speed encoder is factory-calibrated, end-users may perform in-house verification using a handheld tachometer or optical encoder aligned with ISO 17025-accredited procedures. Calibration certificates are available upon request for specific units.
Does the ISM897 support bidirectional operation?
No—the ISM897 is unidirectional only. Reverse flow requires mechanical reorientation of the tubing or integration of external valve manifolds.
What is the maximum allowable backpressure?
Maximum recommended backpressure is 1.5 bar (22 psi) at 230 mL/min with 4.8 mm ID tubing. Performance degrades linearly above this threshold; pressure-limiting valves are advised for closed-loop systems.
