Overview
The Genevac EZ-2 4.0 Bionic Automated Solvent Evaporation Workstation is an engineered solution for high-integrity, reproducible solvent removal in modern discovery and analytical laboratories. Built upon the proven centrifugal vacuum evaporation principle—combining controlled rotational force, precise temperature regulation, and programmable vacuum ramping—the EZ-2 4.0 Bionic delivers consistent sample concentration and lyophilization-grade drying without thermal degradation or cross-contamination. Unlike conventional rotary evaporators or benchtop concentrators, this system operates under full vacuum while rotating samples at optimized speeds to maximize surface area exposure and minimize bumping or foaming. Its architecture supports unattended operation across extended duty cycles, making it suitable for integration into GLP-compliant workflows and regulated environments where auditability, method traceability, and environmental control are mandatory.
Key Features
- Automated lid actuation with wide-aperture design—enables seamless robotic access for sample loading/unloading with repeatable positional accuracy.
- Indexing rotor with programmable stop positions—ensures precise alignment of sample vessels with robotic grippers and liquid handlers.
- Expanded RS232 command set—supports external automation platforms (e.g., Hamilton STAR, Tecan Freedom EVO) for full remote control of lid status, run initiation/termination, defrost cycles, drain activation, and method selection.
- Dedicated automation-compatible sample carriers—featuring positive-lock clamping mechanisms to secure microtubes, vials, and deep-well plates during high-speed rotation under vacuum.
- Temperature-controlled heating shelf (30–80 °C) with PID feedback and calibrated NIST-traceable sensors—ensures uniform thermal delivery across all rotor positions.
- Integrated vacuum management with oil-free diaphragm pump and intelligent pressure ramping—minimizes solvent bumping and preserves labile analytes such as oligonucleotides and PROTACs.
Sample Compatibility & Compliance
The EZ-2 4.0 Bionic accommodates a broad range of vessel formats—including 1.5 mL and 2.0 mL microcentrifuge tubes, 96-well PCR plates, 24-well deep-well blocks, and custom-fit glass vials—without requiring adapter kits. All wetted materials comply with USP Class VI and ISO 10993 biocompatibility standards. The system supports method validation per ICH Q2(R2) guidelines and maintains full audit trail capability when paired with compliant LIMS or ELN systems. Data integrity conforms to FDA 21 CFR Part 11 requirements when used with validated software configurations, including electronic signatures, user-level permissions, and immutable run logs.
Software & Data Management
Operation is managed via Genevac’s proprietary ControlCenter™ software, which provides real-time monitoring of vacuum level, chamber temperature, rotor speed, and elapsed time. Each evaporation method is stored with metadata—including operator ID, date/time stamp, and instrument serial number—for full traceability. Export functions support CSV and PDF report generation with embedded calibration certificates. For enterprise integration, the RS232 interface supports SCPI-like syntax and can be scripted within Python, LabVIEW, or third-party scheduling engines. All firmware updates are digitally signed and verified prior to installation to ensure system integrity.

- Synthetic biology workflows: High-throughput processing of cell lysates, enzymatic reaction mixtures, and metabolite extracts.
- Clinical biomarker studies: Reproducible concentration of plasma, serum, and CSF samples prior to LC-MS/MS analysis.
- Environmental and food safety testing: Residue analysis workflows requiring compliance with EPA Method 1694 and EU SANTE/11312/2021.
FAQ
Does the EZ-2 4.0 Bionic require external vacuum or cooling sources?
No—it integrates a maintenance-free diaphragm vacuum pump and air-cooled condenser; no chilled water or compressed air connections are needed.
Can the system be validated for GMP use?
Yes—IQ/OQ documentation packages are available, and the platform supports 21 CFR Part 11-compliant electronic records when deployed with approved software configurations.
What is the maximum rotational speed and corresponding g-force?
The indexing rotor operates up to 1,800 rpm, delivering up to 500 × g at the tube bottom—optimized for rapid solvent removal while maintaining sample integrity.
Is remote monitoring supported over Ethernet or Wi-Fi?
The standard configuration uses RS232 for automation; optional Ethernet-to-RS232 gateways enable network-based supervision via SNMP or Modbus TCP in facility-wide infrastructure.
How does the system handle high-boiling-point solvents like DMSO or DMF?
Through dynamic vacuum ramping and staged temperature profiles, the EZ-2 4.0 Bionic safely removes challenging solvents without compromising heat-sensitive targets—validated using ASTM E2656-20 protocols for residual solvent quantification.
