HEL BioXplorer 400 Parallel Benchtop Bioreactor System

Overview

The HEL BioXplorer 400 is a modular, parallel benchtop bioreactor system engineered for scalable process development in microbial fermentation, mammalian cell culture, and synthetic biology applications. It implements a dual-mode control architecture—combining precise thermal regulation, independent gas blending, real-time redox and pH monitoring, and configurable agitation—to replicate physiologically relevant bioprocess conditions across multiple vessels simultaneously. Unlike single-vessel systems, the BioXplorer 400 supports true parallel experimentation with four fully isolated reaction channels, enabling statistically robust DOE (Design of Experiments) studies and rapid transition from lab-scale screening (30 mL) to pilot-scale validation (10 L). Its glass construction ensures optical clarity for inline turbidity measurement and compatibility with sterilization-in-place (SIP) and autoclaving protocols—critical for GLP-compliant bioprocess characterization.

Key Features

• Fully independent control of temperature, agitation, pH, dissolved oxygen (via redox), and gas flow across all four reactors
• Modular vessel compatibility: interchangeable borosilicate glass reactors ranging from 30 mL to 10 L—including three mini-scale options (30–100 mL, 100–350 mL, 175–500 mL) and five benchtop sizes (0.5 L, 1 L, 2 L, 5 L, 10 L)
• Dual agitation modes: high-torque magnetic coupling (200–1200 rpm) for small-volume vessels; overhead mechanical drive with dynamic seal options (mechanical or magnetic) for larger vessels (50–1500 rpm)
• Integrated sensor suite: autoclavable pH and redox electrodes, optional inline turbidity probe, and configurable gas inlet (air or 4-channel mixed gas including CO₂ for pH modulation)
• Thermal management via jacketed circulation: Peltier-based heating/cooling for mini-reactors; external chiller integration (optional computer-controlled) for 1 L+ vessels
• Reaction calorimetry add-on module available for real-time heat flow quantification during exothermic/endothermic biotransformations

Sample Compatibility & Compliance

The BioXplorer 400 accommodates diverse biological systems—including bacterial cultures (E. coli, Bacillus spp.), yeast (S. cerevisiae, P. pastoris), filamentous fungi, and suspension-adapted mammalian cells—under controlled aerobic, microaerobic, or anaerobic conditions. All wetted parts are constructed from ASTM E438 Type I, Class A borosilicate glass (e.g., Pyrex®-equivalent), compliant with ISO 3585 and USP . Sensors and probes meet IEC 61000-6-2/6-3 EMC standards and are validated for repeated autoclaving at 121°C for 20 minutes. The system supports audit-ready data integrity per FDA 21 CFR Part 11 requirements when configured with electronic signatures, time-stamped audit trails, and role-based user access in the full-function software module.

Software & Data Management

HEL’s BioXplorer Control Suite operates on Windows-based platforms (touchscreen, laptop, or desktop) and comprises three hierarchical modules: (1) Simulation Mode—single-step protocol testing without hardware interaction; (2) Programming Mode—multi-step sequences with conditional branching and inter-channel synchronization; (3) Full-Function Mode—advanced logic-based control, real-time parameter optimization, and automated event-triggered actions (e.g., CO₂ injection upon pH deviation >±0.1 unit). All modules log timestamped raw data (temperature, pH, rpm, gas flow, turbidity) in CSV and HDF5 formats, with optional export to LIMS or ELN systems. Remote 24/7 monitoring is enabled via secure TLS-encrypted HTTP API, supporting integration into centralized lab infrastructure.

Applications

• Strain selection and media optimization for recombinant protein expression
• Scale-down modeling of industrial bioreactors using geometrically and dynamically similar vessels
• Kinetic profiling of enzymatic cascades and whole-cell biocatalysis under controlled redox potential
• Process characterization for regulatory filings (ICH Q5, Q8), including design space definition per QbD principles
• In situ monitoring of biomass growth via turbidity correlation with OD₆₀₀, validated against offline HPLC or qPCR assays
• Thermosensitive pathway induction studies leveraging the system’s ±0.1°C temperature stability across −60°C to 225°C

FAQ

Can the BioXplorer 400 be used for anaerobic fermentations?
Yes—its 4-channel gas manifold supports nitrogen, argon, or hydrogen sparging, and vacuum-rated glass vessels (up to 1 MPa differential) enable strict oxygen exclusion when paired with sterile filtration and glove-box integration.

Is the system compliant with GMP documentation requirements?
When deployed with the Full-Function Software Module and validated peripherals, it meets ALCOA+ data integrity criteria and supports 21 CFR Part 11-compliant electronic records, including operator authentication, change history, and immutable audit logs.

How is scalability ensured between mini and benchtop reactors?
HEL provides geometric similarity guidelines (impeller diameter-to-tank diameter ratio, tip speed, power/volume consistency) and offers scale-up consulting services aligned with ISO 13485 and ASTM E2500-13 verification frameworks.

Are third-party sensors (e.g., dissolved O₂, metabolite probes) supported?
The system features open analog/digital I/O ports and Modbus RTU support, enabling integration of validated OEM sensors—including fiber-optic DO probes and enzymatic amperometric glucose/lactate analyzers—via HEL’s certified interface adapters.
