Ismatec ISM830 Compact Multi-Channel Peristaltic Pump

Overview

The Ismatec ISM830 Compact Multi-Channel Peristaltic Pump is an engineered solution for precise, low-to-medium flow fluid handling in analytical, bioprocessing, and quality control laboratories. Based on the well-established peristaltic principle—where rollers compress flexible tubing to displace fluid without contact between pump mechanism and sample—the ISM830 delivers contamination-free, pulse-dampened flow ideal for shear-sensitive media, sterile applications, and multi-stream reagent delivery. Its compact footprint (178 × 102 × 135 mm) supports dense benchtop configurations, while its modular architecture accommodates 2- or 4-channel operation with selectable roller configurations (6-, 8-, or 12-roller heads) to balance flow smoothness, pressure capability, and tube lifetime. Designed for integration into automated workflows, the ISM830 supports both analog and digital control protocols, enabling seamless interfacing with PLCs, SCADA systems, or LIMS platforms under GLP/GMP-aligned operational frameworks.

Key Features

• Compact dual- or quad-channel design occupying minimal bench space while maintaining independent flow control per channel.
• Ertalyte® self-lubricating roller shafts ensure consistent mechanical performance and reduce tubing wear over extended duty cycles.
• Click’n’go™ mini clamp system guarantees repeatable tube loading and optimal occlusion—critical for flow reproducibility across multiple operators and shifts.
• Bi-directional flow control via front-panel tactile switch or remote dry-contact input (DB15), supporting wash-rinse sequences and recirculation protocols.
• High-resolution speed adjustment (1% increments, 0–99% of full scale) with analog input compatibility (0–5 VDC, 0–10 VDC, 0–20 mA, 4–20 mA) for closed-loop feedback integration.
• Digital RS-232 interface (DB9 male) enables full command-and-control—including start/stop, direction reversal, speed setpoint, and status interrogation—via host PC or industrial controller.
• Programmable dispensing modes: continuous flow, timed delivery (0.1 s – 999.9 h), batch volume with inter-step delay, and no-drip aspiration routines to prevent post-dispense dripping.
• Real-time speed monitoring via frequency output signal synchronized to motor rotation, facilitating traceability and audit-ready process validation.

Sample Compatibility & Compliance

The ISM830 is compatible with a broad range of standard peristaltic tubing materials—including Tygon® ST series (e.g., R-3603, R-3607), PharMed® BPT, and silicone—enabling use with aqueous buffers, organic solvents, cell culture media, and mild acids/bases. Flow rates are calibrated using water at 22 °C under zero differential pressure; actual performance varies predictably with fluid viscosity, density, and backpressure. The pump meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), complies with RoHS 2011/65/EU restrictions on hazardous substances, and carries UL certification to UL 61010-1 for laboratory equipment safety. Its analog and digital I/O architecture supports implementation in environments requiring adherence to FDA 21 CFR Part 11 for electronic records and signatures when paired with validated software layers.

Software & Data Management

While the ISM830 operates autonomously via front-panel controls, its RS-232 interface allows integration with custom or third-party software for centralized scheduling, logging, and alarm management. Command sets follow ASCII-based protocol with checksum support, enabling reliable transmission in noisy industrial settings. Analog inputs accept standardized industrial signals, permitting direct linkage to PID controllers or data acquisition systems compliant with IEEE 11073 or OPC UA frameworks. Frequency output provides verifiable rotational feedback for SOP-driven calibration checks. Audit trails—including timestamped start/stop events, speed changes, and direction toggles—can be captured externally to satisfy ISO/IEC 17025 or ASTM E2500 verification requirements.

Applications

• Automated liquid handling in HPLC and IC mobile phase delivery systems where pulsation minimization improves baseline stability.
• Multi-reagent dosing in clinical analyzers and ELISA wash stations requiring synchronized, non-cross-contaminating streams.
• Continuous perfusion culture in bioreactors, including stem cell expansion and monoclonal antibody production workflows.
• In-line sampling and dilution in environmental monitoring systems (e.g., wastewater nutrient analysis) with minimal maintenance downtime.
• Calibration standard delivery in metrology labs performing volumetric accuracy verification per ISO 8655-3.
• Process validation studies under GMP conditions where programmable dispensing and electronic event logging support Annex 11 compliance.

FAQ

What tubing sizes are supported by the ISM830?
The pump accepts standard peristaltic tubing with internal diameters from 0.13 mm to 3.17 mm (e.g., Tygon® ST R-3603 through SC0224), with flow capacity dependent on ID, wall thickness, and roller configuration.
Can the ISM830 operate under backpressure?
Yes—performance is specified at zero differential pressure, but it maintains stable flow up to ~1.5 bar (22 psi) with appropriate tubing selection and roller count; higher pressures require validation per application-specific fluid properties.
Is firmware upgrade capability available?
No field-upgradable firmware is provided; however, all operational parameters are configurable via serial commands or analog inputs, ensuring long-term functional adaptability without hardware modification.
Does the ISM830 support 21 CFR Part 11 compliance?
The device itself does not include built-in electronic signature or audit trail storage, but its deterministic I/O behavior and time-stamped external logging capability enable compliant system-level implementation when integrated with validated software infrastructure.
What is the expected service life of the Ertalyte® rollers?
Under typical lab use (8 h/day, 5 days/week), Ertalyte® rollers demonstrate >10,000 hours of continuous operation with negligible wear-induced flow drift, as verified per ISMATEC’s internal accelerated life testing per ISO 9001 procedures.
