Tecan Cavro XMP 6000 Multi-Channel Syringe Pump

Overview

The Tecan Cavro XMP 6000 Multi-Channel Syringe Pump is an engineered solution for high-precision, parallel liquid handling in automated laboratory workflows. Based on the well-established Cavro electromechanical syringe pump architecture, the XMP 6000 integrates stepper motor-driven plunger actuation with programmable valve manifolds to deliver deterministic fluid displacement across up to eight independent channels. Its operation relies on open-loop microstepping control with calibrated step-to-volume mapping—enabling reproducible volumetric delivery without real-time pressure or flow feedback. Designed for integration into OEM instruments and modular lab automation platforms, the XMP 6000 supports both continuous infusion and discrete dispensing protocols under time-synchronized or event-triggered control. The pump’s mechanical design complies with ISO 8573-1 Class 4 purity requirements for non-lubricated motion components, ensuring compatibility with sensitive biological and analytical applications where particulate or hydrocarbon contamination must be minimized.

Key Features

• Modular channel configuration: Supports 2-, 4-, 6-, or 8-channel setups with individual plunger control and synchronized stepping
• High-resolution actuation: 6,000 full steps per revolution (48,000 microsteps) enables sub-nanoliter per step resolution when paired with small-volume syringes (e.g., 50 µL)
• Valve flexibility: Compatible with standard 3-way, bypass-mode 3-way, and 3+1 (one common inlet, three selectable outlets) configurations for complex routing schemes
• Wide syringe compatibility: Accepts glass or plastic syringes from 50 µL to 5 mL with standardized Luer-lock or threaded mounting interfaces
• Deterministic motion control: 60 mm plunger stroke accommodates full-volume actuation across all supported syringe sizes while maintaining linearity and minimal hysteresis
• Industrial-grade communication: Native support for RS-232, RS-485, and CAN bus protocols facilitates robust integration into distributed control systems and SCADA environments
• Low-maintenance architecture: Brushless stepper motors and polymer-coated lead screws eliminate lubricant migration risks—critical for GLP-compliant assay development and regulated QC environments

Sample Compatibility & Compliance

The XMP 6000 is compatible with aqueous buffers, organic solvents (including acetonitrile and methanol), low-viscosity cell culture media, and diluted protein solutions—provided chemical compatibility with PTFE seals and stainless-steel wetted parts is verified per application. It does not support high-viscosity fluids (>100 mPa·s), abrasive suspensions, or gases. The pump meets IEC 61326-1 for electromagnetic compatibility (EMC) in laboratory environments and conforms to CE marking requirements for safety (EN 61010-1). While not certified as a medical device, its performance characteristics align with ASTM D3418 for thermal analysis pump validation and USP guidelines for analytical instrument qualification. Full traceability of calibration parameters—including step-size mapping per syringe size—is retained in non-volatile memory for audit readiness.

Software & Data Management

The XMP 6000 operates via ASCII command protocol over serial or CAN interfaces, enabling direct integration with LabVIEW, Python (pySerial/pyCAN), MATLAB, or custom C/C++ host applications. Tecan provides a comprehensive command reference manual and sample scripts for common use cases including gradient elution, multi-reagent addition, and timed serial dilutions. No proprietary runtime or driver installation is required. For systems requiring electronic records and audit trails, the pump’s command-response architecture supports timestamped logging of all motion and valve commands—facilitating compliance with FDA 21 CFR Part 11 when implemented within a validated software environment. Firmware updates are delivered via UART bootloading and include checksum-verified integrity checks.

Applications

• Automated sample preparation for HPLC, LC-MS, and capillary electrophoresis systems
• Multi-reagent dispensing in ELISA, PCR setup, and NGS library preparation workstations
• Controlled reagent addition in kinetic enzyme assays and stopped-flow spectroscopy
• Calibration standard delivery in ICP-MS and atomic absorption spectrometry
• OEM integration into diagnostic analyzers, microfluidic controllers, and point-of-care testing platforms
• Parallel solvent delivery in combinatorial chemistry reactors and flow chemistry modules

FAQ

What syringe sizes are supported?
The XMP 6000 accepts syringes ranging from 50 µL to 5.0 mL, including 100 µL, 250 µL, 500 µL, 1.0 mL, and 2.5 mL variants. Each size requires corresponding mechanical calibration to maintain accuracy.
Can the pump operate in closed-loop mode with flow sensors?
No—the XMP 6000 is an open-loop, position-controlled device. Flow rate is derived from step count, microstep resolution, and syringe cross-sectional area. Integration with external flow meters is possible but requires host-level synchronization and compensation logic.
Is firmware upgrade capability available?
Yes—firmware updates are performed via UART interface using Tecan-provided binaries and require no hardware modification. Version history and release notes are published in the technical support portal.
Does the pump support GMP/GLP documentation packages?
While the XMP 6000 itself is not supplied with IQ/OQ documentation, Tecan provides Design Qualification (DQ) summaries, test reports, and calibration certificates upon request—enabling users to develop site-specific validation protocols compliant with ISO/IEC 17025 and Annex 11.
How is valve timing synchronized across multiple channels?
All valves and plungers are driven from a shared clock domain within the controller board. Inter-channel timing jitter is less than 100 µs, supporting tightly coordinated dispensing events such as simultaneous reagent addition across microtiter plate rows.
