Agilent BenchCel Liquid Handling Workstation

Overview

The Agilent BenchCel Liquid Handling Workstation is a modular, benchtop-scale automation platform engineered for high-integrity microplate manipulation in regulated and high-throughput laboratory environments. Unlike general-purpose liquid handlers, the BenchCel is purpose-built as a microplate orchestrator—not a pipetting system—specializing in the precise, repeatable transport, orientation, staging, and conditioning of SBS-compliant microplates (96-, 384-, and 1536-well formats). Its core operational principle relies on coordinated robotic gantry motion, vacuum-based plate gripping, and servo-controlled Z-axis positioning to execute deterministic plate transfers between fixed deck locations and peripheral instrumentation. Designed for integration into end-to-end assay workflows—including sample preparation, compound screening, QC release testing, and biobanking—the BenchCel eliminates manual plate handling bottlenecks while maintaining full traceability and positional fidelity across all plate movements.

Key Features

• Modular deck architecture supporting 2, 4, or 6 independently configurable SBS microplate racks—each accommodating up to 60 standard plates with adjustable height stops for variable stack thicknesses.
• Deterministic plate transfer cycle time of ≤8 seconds from rack to peripheral device (e.g., PlateLoc sealer, barcode printer, or centrifuge), validated under continuous operation at ambient laboratory conditions (20–25°C, 30–70% RH).
• Vacuum-assisted gripper mechanism with real-time pressure monitoring ensures secure plate engagement without deformation or edge lift—critical for preserving seal integrity prior to thermal sealing or downstream detection.
• Integrated encoder-based position feedback and homing routines guarantee sub-millimeter repeatability (<±0.15 mm) across all X-Y-Z axes, enabling reliable registration with external instruments requiring precise plate alignment (e.g., readers, imagers, or dispensers).
• Benchtop footprint (W × D × H: 762 × 610 × 508 mm) optimized for placement beneath fume hoods, inside biosafety cabinets, or adjacent to analytical instrumentation without compromising ergonomic access or service clearance.

Sample Compatibility & Compliance

The BenchCel workstation is validated for use with all ANSI/SBS-standard microplates—including polypropylene, polystyrene, and cyclic olefin copolymer (COC) formats—regardless of skirt type (full, half, or non-skirted) or lid configuration (adhesive, heat-seal, or cap-mat). It supports plates with barcoded bottoms or side labels compliant with ISO/IEC 15420 and GS1-128 standards. From a regulatory standpoint, the system operates within the scope of FDA 21 CFR Part 11 when deployed with VWorks software configured for electronic signatures, audit trail logging, and role-based access control. Full IQ/OQ documentation packages are available upon request to support GLP, GMP, and ISO 17025 laboratory accreditation requirements.

Software & Data Management

Controlled exclusively via Agilent’s VWorks Automation Control Software, the BenchCel provides a graphical workflow builder with drag-and-drop protocol sequencing, parameter validation checks, and real-time status visualization. All plate movements are logged with timestamps, operator ID (if authenticated), source/destination coordinates, and error codes—generating immutable audit trails compliant with ALCOA+ principles. VWorks supports direct integration with LIMS (e.g., LabVantage, Thermo SampleManager) and ELN systems via ASTM E1578-compliant API endpoints. Optional modules include automated calibration verification reporting and periodic performance qualification (PPQ) templates aligned with USP and ISO/IEC 17025 clause 6.5.

Applications

• High-volume biobank plate staging and archival—automated transfer from storage racks to thaw stations, aliquoting modules, or cryo-readers.
• QC release workflows for pharmaceutical intermediates: sequential plate routing through barcode labeling → centrifugation → thermal sealing → spectrophotometric analysis.
• Cell-based assay preparation: timed coordination between plate unsealing, reagent addition (via external dispenser), incubation, and post-incubation sealing for stability testing.
• Regulated environmental testing labs performing EPA Method 1600-series analyses, where plate chain-of-custody tracking and tamper-evident sealing are mandatory.
• Academic core facilities serving multi-user scheduling—VWorks’ user-level permissions and job queuing enable fair resource allocation without administrative overhead.

FAQ

Does the BenchCel perform liquid dispensing or pipetting?
No. The BenchCel is a microplate transport and conditioning system only. It does not aspirate, dispense, or mix liquids. Integration with third-party liquid handlers (e.g., Agilent Bravo, Tecan Fluent) requires external synchronization via digital I/O or TCP/IP commands.
Can it handle non-SBS plates such as PCR strips or custom labware?
No. Mechanical and software constraints limit operation to ANSI/SBS-compliant microplates (dimensions: 127.76 × 85.48 mm, ±0.2 mm tolerance). Non-standard formats require custom engineering validation and are not supported out-of-the-box.
Is remote monitoring or troubleshooting supported?
Yes. VWorks includes secure remote desktop capability (TLS 1.2 encrypted) and diagnostic telemetry export (CSV/JSON) for predictive maintenance alerts, subject to network policy approval and firewall configuration.
What safety certifications does the system carry?
The BenchCel complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE, UL 61010-1, and CSA C22.2 No. 61010-1 certifications. Laser Class 1 classification applies to all integrated optical sensors.
