Ismatec® Compact Multi-Channel Peristaltic Pump Model 78016-00

Overview

The Ismatec® Compact Multi-Channel Peristaltic Pump Model 78016-00 is an engineered solution for precise, low-maintenance fluid handling in analytical laboratories, bioprocessing workflows, and continuous-flow chemistry applications. Designed on the principle of peristaltic displacement—where rollers compress flexible tubing to generate positive displacement—the pump delivers pulse-dampened flow through its 12-roller head architecture, minimizing flow pulsation and enhancing volumetric reproducibility across extended operation cycles. Its compact dual-channel configuration supports simultaneous independent delivery of reagents, standards, or samples without cross-contamination, making it suitable for HPLC mobile phase delivery, cell culture media perfusion, environmental sampling systems, and automated titration setups. The pump operates without valves, seals, or wetted moving parts beyond the tubing itself—ensuring intrinsic chemical compatibility and eliminating risk of sample carryover or mechanical leakage.

Key Features

• 12-roller pump head design for reduced flow pulsation and improved linearity across the full speed range (3.2–160 rpm)
• Dual-channel architecture with independent speed control per channel, enabling synchronized or asynchronous fluid delivery
• Click’n’go™ mini clamp system for rapid, tool-free tubing installation and channel reconfiguration—reducing setup time and operator variability
• Self-lubricating roller mechanism eliminates routine maintenance and extends service intervals between inspections
• Analog speed control with 1% incremental resolution (0–99% full scale), supporting fine-tuned flow rate modulation
• Remote operation capability via dry-contact inputs for start/stop/polarity reversal, and frequency output for real-time speed feedback
• Adjustable occlusion via optional bite-adjustable mini clamps (e.g., ZD-07624-64, ZD-78016-98) to optimize tube compression for varied wall thicknesses and material types
• Maximum pressure rating of 22 PSI ensures compatibility with moderate backpressure environments such as inline filters or packed columns

Sample Compatibility & Compliance

The Model 78016-00 accommodates standard silicone, Viton®, Tygon®, and PharMed® tubing sizes compatible with 3-roller cassette configurations (e.g., Masterflex L/S® 13, 14, 16, 17). Its tubing-only wetted path enables seamless adaptation to aggressive solvents, biological buffers, and viscous media without material incompatibility concerns. While the pump itself does not carry regulatory certification, its design aligns with GLP and GMP operational expectations: traceable speed control, repeatable occlusion settings, and mechanical stability support audit-ready documentation when integrated into validated systems. When paired with FDA-compliant tubing and used within defined process parameters, it meets requirements for USP Analytical Instrument Qualification and supports 21 CFR Part 11–compliant data acquisition when interfaced with compliant SCADA or LIMS platforms.

Software & Data Management

As a stand-alone analog-controlled unit, the 78016-00 does not include embedded firmware or touchscreen interface. However, its analog I/O architecture—featuring 0–10 VDC speed input, TTL-compatible start/stop signals, and 0–10 kHz frequency output—enables integration into programmable logic controllers (PLCs), LabVIEW-based automation suites, or custom Python-driven DAQ systems. For users requiring digital command protocols, compatible Ismatec models (e.g., 78016-42 series) offer RS-232 serial communication, analog setpoint modulation, and four programmable dispensing modes (flow rate, time, volume batch, dripless mode). All firmware-enabled variants log runtime hours and support password-protected parameter locking—features essential for multi-user lab environments subject to internal QA review.

Applications

• Continuous-flow synthesis reactors requiring stoichiometric reagent addition
• Automated calibration standard dilution in ICP-MS and AAS sample introduction systems
• In-line filtration and ultrafiltration feed control in protein purification skids
• Environmental water quality monitoring stations with multi-analyte sensor arrays
• Microfluidic platform priming and reagent loading in diagnostic assay development
• Cell culture bioreactor perfusion loops where shear-sensitive mammalian cells demand gentle, non-pulsatile flow

FAQ

What tubing sizes are compatible with the 78016-00 pump head?
Standard tubing inner diameters of 0.125–0.250 inches (3.2–6.4 mm) are supported using L/S® 13–17 cassettes; exact fit depends on selected mini clamp occlusion setting.
Can this pump be integrated into a PLC-controlled process line?
Yes—via its analog voltage input (0–10 VDC), dry-contact control terminals, and frequency output signal, enabling closed-loop speed regulation and status monitoring.
Is tubing life affected by the 12-roller design compared to 6-roller alternatives?
The 12-roller architecture distributes compression force over more contact points, reducing localized stress per revolution and extending typical tubing service life by up to 40% under equivalent flow conditions.
Does the pump support reversible operation for bidirectional fluid transfer?
Yes—direction reversal is enabled via external polarity-switching contact input, allowing controlled backflushing or recirculation without manual tubing reconfiguration.
Are replacement mini clamps and tubing cassettes available as spare parts?
Yes—Cole-Parmer part numbers ZD-78016-98 (spare Click’n’go™ clamp), ZD-07624-64 (bite-adjustable clamp), and compatible L/S® tubing kits are stocked globally through authorized distributors.
