WIGGENS Vdose ELITE Peristaltic Pump

Overview

The WIGGENS Vdose ELITE Peristaltic Pump is a precision-engineered fluid handling instrument designed for laboratory-scale liquid transfer, dispensing, and continuous flow applications where contamination control, shear-sensitive sample integrity, and reproducible volumetric accuracy are critical. Utilizing the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the Vdose ELITE eliminates fluid contact with internal pump components, ensuring zero dead volume, no cross-contamination between samples, and full compatibility with aggressive, viscous, or sterile media. Its microstepping stepper motor delivers high-resolution speed control across a broad operational range (0.5–400 RPM), enabling stable low-flow delivery down to 0.1 mL/s and robust throughput up to 30.0 mL/s. The pump’s modular architecture supports single-, dual-, and 5-channel pump head configurations, making it adaptable to diverse workflows in bioprocessing, pharmaceutical formulation, food science, and analytical chemistry.

Key Features

• Chemical-resistant 4-inch LCD touchscreen interface with intuitive icon-based navigation and multilingual support (English, German, French, Spanish, Chinese)
• Bidirectional rotation capability for forward/reverse dispensing, priming, and backflush operations
• Programmable dispensing with nine user-storable methods, including adjustable start ramp profiles (five slope options) and programmable delay intervals (0.5–99.9 s)
• High-accuracy dispensing down to 0.01 mL per step, with overall system accuracy maintained at ≤ ±1% across the full flow range
• Low-profile chassis (330 mm height) optimized for integration into biosafety cabinets, fume hoods, and automated workstations
• Modular pump head design supporting interchangeable heads: standard single-head, dual-head stackable configuration, and 5-channel micro-dispensing head
• Compatibility with silicone or fluoropolymer tubing in inner diameters of 2, 3, 6, and 8 mm, accommodating wall thicknesses of 1.6 mm or 2.4 mm for tailored pressure and flow characteristics
• Remote operation via RS-232 or optional analog/digital I/O interface for integration into LIMS or SCADA environments

Sample Compatibility & Compliance

The Vdose ELITE is validated for use with shear-thinning, high-viscosity, abrasive, and chemically aggressive liquids—including syrups, cell suspensions, enzyme solutions, organic solvents, and acidic or alkaline reagents—without degradation of performance or tubing life. Its fully enclosed drive train and sealed electronics meet IP20 ingress protection standards. Regulatory compliance includes UL 61010-1, CSA C22.2 No. 61010-1, CE marking under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), RoHS 2011/65/EU, and WEEE 2012/19/EU. While not inherently GLP/GMP-certified, its audit-ready programmable parameters, non-volatile method storage, and traceable operation logs support alignment with ISO/IEC 17025, USP , and FDA 21 CFR Part 11 requirements when deployed within validated SOPs.

Software & Data Management

The pump operates autonomously without external software; however, its RS-232 serial interface enables bidirectional communication with host systems for command-driven automation and data logging. All nine onboard programs retain settings—including speed, direction, volume, ramp profile, and delay—across power cycles. Method recall is achieved via numeric keypad or touch selection, minimizing operator input error. For laboratories requiring electronic records, timestamped run logs (including start/stop times, total dispensed volume, and active program ID) can be exported via terminal emulation or integrated into third-party control platforms. Firmware updates are performed locally using USB-to-serial adapters, ensuring long-term maintainability without vendor dependency.

Applications

• Microbial culture media preparation and inoculum transfer under aseptic conditions
• Accurate dosing of excipients and APIs during pharmaceutical liquid formulation and lyophilization buffer preparation
• Controlled addition of flavorings, preservatives, or enzymes in food and beverage R&D
• Continuous feed of reactants or catalysts in small-scale chemical synthesis and flow chemistry setups
• Calibration solution delivery in analytical instrument sample introduction systems (e.g., ICP-OES, HPLC autosamplers)
• Cell-laden hydrogel extrusion in tissue engineering scaffolds where shear stress must remain below critical thresholds

FAQ

What tubing sizes and wall thicknesses are supported?
The Vdose ELITE accommodates tubing with inner diameters of 2 mm, 3 mm, 6 mm, and 8 mm, and wall thickness options of 1.6 mm or 2.4 mm—enabling optimization of flow rate, pressure resistance, and pulse dampening.
Can multiple pump heads be operated simultaneously from one controller?
Yes—the system supports stacking of up to two standard pump heads on a single base unit; alternatively, the 5-channel micro-dispensing head provides independent control of five parallel lines.
Is calibration required before first use?
Factory calibration is performed prior to shipment. Users may perform quick verification using gravimetric measurement; the intuitive menu-guided calibration routine reduces adjustment steps to under two minutes.
Does the pump support continuous flow mode as well as discrete dispensing?
Yes—two distinct operational modes are available: “Dispense Mode” for precise volume delivery and “Continuous Flow Mode” for steady-state pumping, both fully programmable and reversible.
How is compliance with regulatory documentation standards addressed?
While the device itself does not include built-in electronic signature or audit trail features, its deterministic behavior, parameter persistence, and remote command logging enable integration into compliant workflows when paired with validated host software and procedural controls.
