Tecan Freedom EVO NAE Workstation for Fully Automated Nucleic Acid Extraction and Purification

Overview

The Tecan Freedom EVO NAE Workstation is a modular, benchtop liquid handling platform engineered for fully automated nucleic acid extraction and purification across diverse biological matrices. Built upon the proven Freedom EVO architecture, this system implements precise liquid handling robotics—featuring multi-channel pipetting arms with adjustable tip spacing, integrated grippers, and temperature-controlled deck zones—to execute complex, multi-step protocols without manual intervention. Its core operational principle relies on programmable fluid transfer, timed incubation, vacuum-driven filtration, or magnetic bead capture and washing cycles, depending on the selected separation chemistry. Unlike fixed-function extractors, the NAE Workstation operates as a programmable automation engine: it does not perform extraction *per se*, but rather orchestrates reagent dispensing, sample mixing, incubation, binding, wash, elution, and plate movement in strict accordance with user-defined SOPs. This architecture enables method portability, protocol version control, and seamless integration into end-to-end workflows—from primary sample receipt to library prep readiness.

Key Features

• Modular hardware design supporting interchangeable functional units: Te-VacS vacuum manifold for solid-phase 96-well plate processing; Te-MagS magnetic separation module with dual-position static magnets for high-efficiency bead retention and wash optimization; optional heated/cooled deck zones for temperature-sensitive lysis or enzymatic steps.
• Robust liquid handling performance: 8-channel pipetting arm with volume range 5–1,000 µL, CV ≤ 3% at 100 µL; independent tip ejection and wash stations to prevent cross-contamination; real-time liquid level sensing for adaptive aspiration in viscous or foaming samples.
• Open-system compatibility: Supports third-party consumables—including standard ANSI/SLAS-format microplates, deep-well plates, filter plates, and magnetic bead-compatible tubes—without proprietary lock-in.
• Instrument-level traceability: FluentControl™ software logs all robotic actions, reagent lot numbers (when scanned), operator ID, timestamp, and environmental conditions (e.g., deck temperature) per run, satisfying ALCOA+ data integrity requirements.
• Scalable throughput: Configurable for low- to mid-throughput labs (1–48 samples/run) up to high-volume operations via parallel module deployment (e.g., dual Te-VacS units on one deck).

Sample Compatibility & Compliance

The Freedom EVO NAE accommodates raw input materials including whole blood, serum, plasma, cerebrospinal fluid (CSF), saliva, buccal swabs, cultured cells, and fresh/frozen tissue homogenates. It supports isolation of genomic DNA, total RNA, mRNA, viral nucleic acids (DNA/RNA), and plasmid DNA using chemistries based on silica-membrane spin columns, magnetic bead binding, or vacuum-assisted filtration. All validated protocols undergo internal reproducibility testing (n ≥ 3 replicates) and are documented per ISO/IEC 17025 principles. The system meets essential requirements for use in clinical research laboratories operating under CLIA, CAP, or ISO 15189 frameworks; when configured with electronic signatures and audit trail enabled, it supports compliance with FDA 21 CFR Part 11 for regulated nucleic acid preparation used in IVD development or biomarker qualification studies.

Software & Data Management

FluentControl™ v5.x serves as the unified control and documentation interface. It provides drag-and-drop protocol builder functionality, preloaded method templates for common kit manufacturers (Promega Maxwell®, Thermo Fisher MagMAX™, MACHEREY-NAGEL NucleoSpin®), and export options for CSV, PDF, and XML output formats compatible with LIMS integration. Audit trails record every user action, parameter change, and instrument event with immutable timestamps and hash-verified logs. Data backups follow ITAR-compliant encryption standards; local storage is retained for ≥ 3 years unless superseded by institutional archival policy. Remote monitoring via secure HTTPS connection enables real-time status checks without compromising firewall integrity.

Applications

• High-fidelity gDNA extraction from FFPE tissues prior to NGS library construction.
• Automated RNA isolation from low-input clinical specimens (e.g., CSF, fine-needle aspirates) with RNase-free workflow enforcement.
• Parallel purification of viral RNA from nasopharyngeal swabs in diagnostic surveillance programs.
• mRNA enrichment and cleanup for single-cell sequencing sample prep pipelines.
• Plasmid DNA miniprep automation in synthetic biology labs requiring traceable batch records.
• Method development and validation support for novel extraction chemistries under GxP conditions.

FAQ

Does the Freedom EVO NAE include built-in heating or cooling for on-deck incubation?
Yes—optional Peltier-based deck modules provide precise temperature control from 4 °C to 95 °C, enabling on-instrument lysis, binding, or elution steps without external equipment.
Can the system be integrated with downstream PCR or NGS library prep modules?
Absolutely—the Freedom EVO platform supports API-driven integration with third-party thermocyclers, fragment analyzers, and library quantification systems via RS232, TCP/IP, or LabVIEW-compatible drivers.
Is validation documentation provided for regulatory submissions?
Tecan supplies IQ/OQ documentation packages, and application-specific PQ reports can be generated in collaboration with certified service engineers to meet ISO 13485 or ICH GCP expectations.
What level of technical support is available outside regular business hours?
Global 24/7 remote diagnostics and priority escalation paths are included with Tecan Care Service contracts, covering firmware updates, troubleshooting, and emergency protocol recovery assistance.
