ATS AH-D400 High-Pressure Homogenizer

Overview

The ATS AH-D400 High-Pressure Homogenizer is an industrial-grade, floor-standing laboratory homogenizer engineered for reproducible cell disruption, nanoemulsion formation, and colloidal dispersion under precisely controlled high-pressure conditions. It operates on the principle of microfluidic shear and cavitation—where samples are forced through a narrow, geometrically optimized interaction chamber at pressures up to 1500 bar, inducing intense mechanical stress that disrupts cellular membranes, fragments aggregates, or reduces particle size to submicron or nanoscale distributions. Designed for GMP-aligned research environments, the AH-D400 meets CE safety requirements and integrates core engineering features essential for consistent process transfer—from bench-scale formulation development to preclinical batch production.

Key Features

• High-Pressure Performance: Rated for continuous operation at 1500 bar (max design 2000 bar), enabling efficient lysis of robust microbial cells (e.g., E. coli, yeast) and hard-to-lyse mammalian lines (CHO, HEK293, Vero, Sf9) without chemical or enzymatic additives.
• Precision Flow Control: Integrated variable-frequency drive (VFD) allows stepless adjustment of flow rate between 30–40 L/h, supporting scalable process optimization and minimizing shear-induced degradation during sensitive biopolymer processing.
• Digital Pressure Monitoring & Safety Architecture: A calibrated digital pressure transducer (0–2000 bar, ±10 bar accuracy) feeds real-time data to the control interface; programmable overpressure cutoff halts operation if user-defined safety thresholds are exceeded.
• Zero-Residue Sample Handling: Equipped with an integrated automatic exhaust valve and self-draining fluid path geometry, ensuring complete sample recovery and eliminating cross-contamination risk—critical for high-value biologics or toxic compounds.
• Thermal Management: Built-in heat exchanger maintains sample temperature stability during extended runs, mitigating thermal denaturation of proteins, lipids, or labile nanoparticles.
• Modular & Serviceable Design: Standardized first-stage homogenizing module, replaceable wear components, and tool-free access to critical service points reduce downtime and support long-term operational reliability.

Sample Compatibility & Compliance

The AH-D400 accommodates aqueous, viscous, and suspension-based matrices across pharmaceutical, food, and advanced materials research. Verified applications include bacterial and insect cell lysis, liposome extrusion, nanostructured lipid carriers (NLCs), protein-stabilized emulsions, plant-based functional beverages, and carbon nanomaterial dispersion (graphene oxide, CNTs). All wetted surfaces comply with USP Class VI–rated materials where applicable. The system supports GLP documentation workflows and aligns with ISO 22000 (food safety), ISO 13485 (medical device manufacturing), and ICH Q5A/Q5D (biotechnology product characterization) expectations. CE marking confirms conformity with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.

Software & Data Management

While the AH-D400 operates via a dedicated digital front panel (no PC dependency), its analog/digital signal outputs (4–20 mA pressure, 0–10 V flow feedback) enable integration into centralized SCADA or LIMS platforms. Optional RS-485 Modbus RTU interface permits remote parameter logging—including pressure setpoint, actual pressure, runtime, and fault codes—for audit-ready traceability. Data retention complies with FDA 21 CFR Part 11 principles when paired with validated third-party acquisition software, supporting electronic signatures and immutable audit trails required in regulated QC laboratories.

Applications

• Mechanical lysis of prokaryotic and eukaryotic cells for recombinant protein extraction and nucleic acid isolation
• Preparation of sterile-filterable liposomal formulations (e.g., mRNA delivery vehicles) and parenteral fat emulsions
• Stabilization of nano-suspensions for poorly water-soluble APIs (BCS Class II/IV)
• Homogenization of dairy and plant-based protein matrices without thermal denaturation
• Exfoliation and dispersion of 2D nanomaterials (graphene, MoS₂) in aqueous or organic media
• Routine quality control of cosmetic emulsions and topical nanocarriers

FAQ

What is the minimum sample volume the AH-D400 can process without compromising homogenization efficiency?
The system achieves full-pressure performance starting from 60 mL using its calibrated inlet circuit and low-volume priming protocol.
Does the AH-D400 support multi-stage homogenization?
It is configured with a single-stage interaction chamber as standard; dual-stage configurations require custom engineering and are not part of the AH-D400 base specification.
Can the unit be validated for use in GMP environments?
Yes—its CE certification, traceable pressure calibration, repeatable flow-pressure profiles, and documented maintenance intervals support IQ/OQ protocols when executed per client SOPs.
Is the cooling system sufficient for continuous operation at 1500 bar?
The integrated heat exchanger maintains ≤10 °C temperature rise under nominal 40 L/h flow at 1200–1500 bar; for ultra-long runs (>4 h), ambient air conditioning ≥22 °C is recommended.
Are spare parts and technical support available outside China?
ATS provides global distributor networks with certified service engineers; critical wear parts (valve seats, gaskets, ceramic plungers) are stocked regionally and shipped with ISO-certified packaging and CoA documentation.
