Sanotac Biolot 100 Automated Protein Purification System

Overview

The Sanotac Biolot 100 Automated Protein Purification System is a modular, benchtop preparative liquid chromatography platform engineered for high-fidelity isolation and purification of proteins, peptides, monoclonal antibodies (mAbs), recombinant therapeutics, polysaccharides, vaccine antigens, plasma-derived biologics, and gene therapy vectors. Built upon classical column chromatography principles—including ion exchange (IEX), size exclusion (SEC), hydrophobic interaction (HIC), and affinity chromatography—the system delivers precise gradient elution control, real-time multi-parameter monitoring, and reproducible fractionation under fully programmable conditions. Its architecture integrates low-pulse PEEK plunger pumps, dual-wavelength UV-Vis detection with auto-switching lamp technology, in-line conductivity and pH sensing, and an intelligent fraction collector—all synchronized via a centralized, validated software environment. Designed for both discovery-stage purification and process development workflows, the Biolot 100 supports scalability from microgram- to milligram-scale preparations while maintaining strict adherence to GLP/GMP-aligned data integrity requirements.

Key Features

• Modular, field-upgradable hardware design enabling flexible configuration for IEX, SEC, HIC, or affinity-based separations
• High-precision dual PEEK plunger pump system delivering flow rates from 0.01 to 100 mL/min with ±0.5% accuracy and ≤0.2 MPa pressure ripple
• Dual-wavelength UV-Vis detector (190–800 nm) with deuterium/tungsten lamp auto-selection, ±1 nm wavelength accuracy, and linear absorbance response up to 2 AU
• Simultaneous real-time monitoring of UV absorbance, conductivity, and pH—critical for buffer exchange validation and gradient fidelity assessment
• PEEK fluidic path throughout the entire flow stream ensures biocompatibility, chemical resistance, and minimal metal ion leaching
• Integrated pump head auto-cleaning function prevents salt crystallization and buffer carryover between runs
• Automated fraction collector supporting 120-tube capacity (2 × 60 positions), with programmable collection modes: standard, sequential, and recirculating
• Manual injection valve with standard 1 mL loop; optional loops available for volume optimization across sample loads
• FDA 21 CFR Part 11–compliant control software featuring electronic signatures, role-based access control, audit trail logging, and method versioning

Sample Compatibility & Compliance

The Biolot 100 accommodates a broad range of biomolecular samples—including intact IgG, His-tagged fusion proteins, disulfide-rich peptides, glycosylated antigens, plasmid DNA, and viral vector particles—without compromising structural integrity. All wetted materials (PEEK, fused silica, stainless steel 316L in non-contact zones) meet USP Class VI biocompatibility standards. The system supports method transfer from analytical to preparative scale and complies with key regulatory frameworks applicable to biopharmaceutical R&D: ISO 9001 quality management, ASTM E2500–13 for equipment qualification, and ICH Q5A/Q5D guidelines for purity assessment of biotech products. Data handling conforms to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), ensuring traceability during internal audits or regulatory inspections.

Software & Data Management

Control and data acquisition are managed through a Windows-native workstation application that supports multi-module synchronization (pumps, detectors, collector, valve switching). Users define, store, and recall complete chromatographic methods—including gradient profiles, collection logic, detector settings, and calibration parameters—with full version history. All user actions, parameter changes, and run events are logged automatically in an encrypted, tamper-evident audit trail. Electronic signatures are enforced at critical decision points (e.g., method activation, fraction acceptance, report finalization), satisfying FDA 21 CFR Part 11 Subpart B requirements for electronic records and signatures. Raw data files (.raw, .csv) and processed reports (.pdf) are exportable with embedded metadata, facilitating integration into LIMS or ELN environments.

Applications

• Purification of recombinant proteins expressed in E. coli, insect, or mammalian cell systems
• Isolation and polishing of monoclonal antibodies post-Protein A capture
• Desalting and buffer exchange of peptide libraries prior to MS analysis
• Fractionation of natural product extracts containing bioactive glycoproteins or polysaccharides
• Downstream processing of viral vectors (AAV, lentivirus) in preclinical gene therapy workflows
• Plasma fractionation for albumin, immunoglobulin G (IVIG), and coagulation factor isolation
• Process development studies supporting tech transfer to clinical manufacturing

FAQ

Does the Biolot 100 support gradient optimization during active runs?
Yes—gradient composition can be modified in real time using the on-the-fly editable gradient function, allowing dynamic adjustment without interrupting separation.
Can the system interface with third-party column ovens or pH meters?
The platform provides analog/digital I/O ports and Modbus TCP support for external device integration, including temperature-controlled columns and calibrated external pH sensors.
Is method validation documentation provided with the system?
Sanotac supplies a comprehensive IQ/OQ protocol package, including test scripts, acceptance criteria, and blank execution records aligned with ASTM E2500 and Annex 15 of the EU GMP Guide.
What maintenance intervals are recommended for the PEEK pump seals?
Under typical usage (≤8 hrs/day, aqueous buffers), PEEK pump seals require replacement every 12–18 months; seal life extends significantly when operating below 10 MPa and avoiding high-salt or viscous mobile phases.
How is data backup and disaster recovery handled in the software?
The software supports scheduled automated backups to network drives or NAS devices, with optional encryption and retention policy enforcement per organizational IT policies.
