Agilent Bravo NGS Liquid Handling Workstation

Overview

The Agilent Bravo NGS Liquid Handling Workstation is a purpose-built, pre-configured automation platform engineered for reproducible, high-integrity next-generation sequencing (NGS) library preparation and target enrichment workflows. Built upon the proven Bravo modular liquid handling architecture, this workstation integrates precision pipetting, microplate manipulation, thermal control modules (e.g., thermocyclers, incubators), and deck-integrated accessories—including barcode readers, lid handlers, and stacker modules—to support end-to-end sample processing from fragmentation to adapter ligation, size selection, amplification, and hybridization capture. Its core measurement principle relies on positive-displacement or air-displacement pipetting with gravimetric calibration traceable to NIST standards, ensuring volumetric accuracy across 0.5–200 µL ranges typical in NGS workflow steps. Designed for GLP-compliant and ISO/IEC 17025-aligned laboratories, the system operates under controlled environmental conditions and supports audit-ready operation in regulated environments such as clinical genomics labs pursuing CAP/CLIA accreditation.

Key Features

• Modular deck architecture enabling flexible integration of third-party instruments (e.g., Agilent TapeStation, Bioanalyzer, or Qubit fluorometers) via standardized API protocols
• Pre-validated, vendor-supported NGS application packages—including Illumina TruSight, Agilent SureSelect, and Thermo Fisher Ion AmpliSeq—pre-loaded with error-handling logic and QC checkpoints
• Intuitive graphical user interface (GUI) with drag-and-drop protocol builder; supports both novice users (via push-button execution) and advanced programmers (via Python-based scripting extension)
• Robust plate-handling capability: accommodates SBS-standard 96-well and 384-well plates, tube racks (1.5/2.0 mL), and PCR strips; integrated gripper with force-sensing feedback prevents plate damage during transfer
• Onboard calibration suite with automated tip detection, liquid level sensing, and aspiration/dispense verification per channel—performed daily or per-run as required by SOPs
• Full traceability: every liquid transfer event logs timestamp, source/destination coordinates, volume, tip ID, and operator credentials in encrypted SQLite database

Sample Compatibility & Compliance

The Bravo NGS workstation handles diverse biological input materials including genomic DNA, FFPE-derived nucleic acids, cfDNA, RNA (for RNA-Seq), and synthetic oligonucleotides. It maintains compatibility with common NGS reagent kits requiring low-volume transfers (e.g., enzymatic fragmentation, end-repair/A-tailing, adapter ligation, PCR cleanup beads). All fluidic pathways are chemically resistant to ethanol, isopropanol, EDTA, and urea-based buffers. The system complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission) standards. For regulated use, it supports 21 CFR Part 11-compliant electronic signatures, role-based access control (RBAC), and full audit trail generation—including user actions, parameter changes, and instrument status events—with export to CSV or PDF for regulatory submission.

Software & Data Management

Controlled by Agilent’s VWorks Automation Control Software (v4.5+), the Bravo NGS enables centralized management of multiple workstations across lab networks. VWorks includes built-in data integrity safeguards: automatic backup of protocols and run logs to network-attached storage (NAS), version-controlled protocol libraries with change history, and real-time monitoring dashboards displaying throughput metrics (samples/hour), error rates, and maintenance alerts. Raw log files adhere to MIAME and MIAPE metadata standards. Integration with LIMS systems (e.g., LabVantage, STARLIMS) is achieved via HL7 or RESTful API interfaces. All software updates undergo rigorous regression testing and are documented per Agilent’s Quality Management System (QMS), certified to ISO 9001:2015.

Applications

• Automated library prep for whole-genome sequencing (WGS), exome sequencing, and targeted panels
• Hybridization-based capture workflows including solution-phase and array-based enrichment
• Single-cell RNA-Seq library construction with cell barcoding and UMIs
• High-throughput genotyping-by-sequencing (GBS) and methylation library preparation (e.g., bisulfite conversion)
• QC-integrated workflows combining quantification (Qubit), sizing (TapeStation), and purity assessment (Nanodrop) prior to sequencing
• Scalable deployment in core facilities supporting >500 samples/week with minimal hands-on time

FAQ

Does the Bravo NGS support dual-indexed library preparation?
Yes—it natively supports dual-indexing via independent pipetting channels with staggered dispensing sequences, validated for Illumina dual-index kits.
Can existing Bravo protocols be migrated to the NGS configuration?
All legacy Bravo protocols written in VWorks are forward-compatible; NGS-specific modules (e.g., bead wash cycles, thermocycler synchronization) require minor parameter updates.
What validation documentation is provided for GxP environments?
Agilent supplies Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) templates aligned with ASTM E2500 and USP , plus a complete DQ package for risk-based validation planning.
Is remote monitoring and troubleshooting supported?
Yes—VWorks includes secure remote desktop access (with two-factor authentication) and diagnostic telemetry reporting to Agilent Technical Support under active service contracts.
