ISMATEC ECOLINE VC-280 WT Peristaltic Pump ISM1078B

Overview

The ISMATEC ECOLINE VC-280 WT Peristaltic Pump ISM1078B is a precision-engineered, single-channel peristaltic pump designed for reliable, pulse-minimized fluid transfer in laboratory and light industrial environments. Operating on the principle of occlusion-based positive displacement, the pump uses a rotating 12-roller head to sequentially compress elastomeric tubing—generating flow without internal wetted parts or mechanical seals. This design ensures complete fluid isolation, eliminating cross-contamination risks and enabling safe handling of sensitive biological media, cell culture supernatants, reagents, and mild corrosives. The ISM1078B is optimized for applications requiring high flow capacity (up to 5,400 mL/min) with fine speed resolution (1% rpm increments), making it suitable for scalable processes—from benchtop bioreactor feed control to continuous analytical sample introduction.

Key Features

• Stainless steel housing with four non-slip leveling feet, supporting stable dual-unit stacking for space-constrained labs.
• Pre-assembled 12-roller pump head with self-centering convex rollers that reduce tube deformation and extend tubing service life—critical for cost-sensitive, high-throughput workflows.
• Tilt-adjustable LED speed display for ergonomic viewing under variable bench configurations.
• Single-knob operation for start/stop/reverse functions—no tooling or calibration required for basic use.
• Analog speed control via standard industrial signals (0–5 VDC, 0–10 VDC, 0–20 mA, 4–20 mA), enabling seamless integration into PLC-controlled systems or data acquisition platforms.
• Digital I/O interface (8-pin DIN connector) supports external start/stop and direction reversal via dry-contact closure—compatible with existing lab automation infrastructure.
• Designed for tubing with 1.6 mm wall thickness and inner diameters from 4.8 to 9.5 mm (3/16–3/8 in), accommodating a broad range of chemically resistant, USP Class VI-certified silicone or thermoplastic elastomer (TPE) tubing.

Sample Compatibility & Compliance

The ISM1078B maintains full fluid path isolation—ideal for shear-sensitive suspensions including mammalian cell cultures, microbeads, and enzyme solutions. Its occlusive pumping mechanism avoids cavitation, foaming, or particle degradation commonly observed in centrifugal or diaphragm alternatives. While the pump itself does not carry regulatory certification, its mechanical architecture and material compatibility support adherence to GLP and GMP documentation requirements when paired with traceable tubing lots and validated operating procedures. The stainless steel enclosure meets IP20 environmental protection standards for indoor laboratory use. Tubing selection must comply with relevant application-specific standards (e.g., ISO 10993 for biocompatibility, FDA 21 CFR 177 for food contact, or ASTM D2000 for elastomer classification).

Software & Data Management

The ISM1078B operates as a stand-alone analog-controlled device and does not include embedded firmware, network connectivity, or proprietary software. However, its analog and digital I/O interfaces allow full integration into third-party control ecosystems—including LabVIEW, MATLAB, Python-based DAQ systems, or SCADA platforms—enabling time-stamped flow logging, closed-loop feedback control, and audit-trail generation. When deployed in regulated environments, users may implement electronic record-keeping per FDA 21 CFR Part 11 by pairing the pump with compliant data acquisition hardware and validation protocols covering instrument qualification (IQ/OQ/PQ), calibration traceability, and change control.

Applications

• Continuous feeding of nutrient media or pH-adjusting agents into bioreactors and chemostats.
• Automated liquid handling in HPLC mobile phase delivery, fraction collector triggering, and inline dilution systems.
• Controlled perfusion in organ-on-chip and 3D tissue culture platforms.
• Reagent dispensing in ELISA, PCR setup, and automated immunoassay workstations.
• Waste removal and buffer exchange in membrane filtration and dialysis rigs.
• Calibration fluid delivery in flow cytometry and particle size analyzer systems.

FAQ

What tubing sizes are compatible with the ISM1078B?

The ISM1078B is configured for tubing with a 1.6 mm wall thickness and an inner diameter between 4.8 mm and 9.5 mm (3/16–3/8 in). Compatible tubing must be rated for repeated compression at up to 350 rpm.
Does the pump support remote start/stop via digital signal?

Yes—the 8-pin DIN connector accepts dry-contact closure signals for start/stop and direction reversal, enabling synchronization with timers, sensors, or programmable logic controllers.
Is the speed resolution adjustable in 1% increments?

Yes—manual keypad control provides discrete speed adjustment in 1% rpm steps across the full 3.5–350 rpm range.
Can the ISM1078B be used in sterile processing environments?

While the pump housing is cleanable and non-porous, it is not autoclavable or rated for ISO Class 5 environments. Sterility must be maintained through aseptic tubing installation, gamma-irradiated tubing, and appropriate barrier filters upstream/downstream.
What is the maximum continuous duty cycle?

ISMATEC specifies continuous operation at rated speed and load; thermal management is ensured by passive convection cooling and low-friction roller geometry—no forced-air fan is required.
