HRH-XP2020 Automated Smart Plate Washing Station for Pharmaceutical Aerodynamic Testing

Overview

The HRH-XP2020 Automated Smart Plate Washing Station is an engineered solution for standardized post-collection sample preparation in pharmaceutical aerodynamic testing. Specifically designed to interface with Next-Generation Impactor (NGI) collection plates—particularly the 8-stage stainless-steel or polycarbonate cups used in cascade impactor studies—the device performs controlled, low-shear orbital agitation to facilitate complete dissolution of deposited active pharmaceutical ingredients (APIs) in extraction solvents. Unlike manual vortexing or pipette-based mixing, which introduce operator-dependent variability and risk cup contamination or spillage, the HRH-XP2020 applies precise angular oscillation under programmable parameters, ensuring uniform wetting and mass transfer across all collection stages. Its operational principle relies on repeatable mechanical tilting motion rather than rotational spinning, minimizing foam formation and preserving analyte integrity—critical for quantitative HPLC or LC-MS analysis downstream. The system supports regulatory alignment with USP Chapter “Aerodynamic Particle Size Distribution” and ISO 27427:2013 “Inhalation aerosols — Determination of aerodynamic particle size distribution,” where reproducibility of extraction efficiency directly impacts reported fine particle fraction (FPF) and mass median aerodynamic diameter (MMAD).

Key Features

• NGI plate–optimized mechanical interface: Accommodates standard 8-stage NGI collection trays without adapter modification; ensures stable positioning during oscillation.
• Programmable tilt dynamics: Adjustable amplitude (±5° to ±20°), speed (1–20°/s), and cycle count (1–30,000) via intuitive LED display and membrane keypad.
• High positional fidelity: Closed-loop angular control with ±1° repeatability over full lifecycle, validated per ISO 9001 calibration traceability protocols.
• Low-power, low-noise architecture: 60 W brushless DC motor drive with thermal overload protection; operates silently in ISO Class 5–7 cleanroom-adjacent environments.
• Durable, cleanroom-compatible construction: Anodized aluminum frame and chemical-resistant polymer housing; surface finish compliant with ISO 14644-1 particulate limits.

Sample Compatibility & Compliance

The HRH-XP2020 is validated for use with NGI collection cups fabricated from medical-grade stainless steel (AISI 316L) and USP Class VI-certified polycarbonate. It accommodates both aqueous and organic solvent systems—including phosphate-buffered saline (PBS), isopropanol/water mixtures, and methanol—without degradation of structural components. All motion parameters are documented in instrument logs with timestamped metadata, supporting GLP-compliant audit trails. When integrated into a validated APSD testing workflow, the device contributes to data integrity requirements under FDA 21 CFR Part 11 (electronic records/signatures) and EU Annex 11 (computerized systems), provided software-defined settings are password-protected and change-controlled.

Software & Data Management

While the HRH-XP2020 operates as a standalone embedded system, its parameter configuration supports exportable setup profiles via USB-C port (firmware v2.3+). Each run generates a local .csv log file containing start time, total cycles executed, final angle position, and motor current signature—enabling correlation with analytical results in LIMS or ELN platforms. Optional RS-485 Modbus RTU interface allows integration into centralized laboratory automation systems for automated scheduling and remote status monitoring.

Applications

• Standardized API extraction from NGI stage cups prior to HPLC-UV or LC-MS quantification.
• Method development and validation for inhaled product dissolution kinetics under ICH Q5C stability conditions.
• Comparative studies of formulation performance across multiple batches using identical agitation parameters.
• Supporting quality control release testing for metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and soft-mist inhalers (SMIs).
• Facilitating compliance with regulatory submissions requiring demonstration of analytical method robustness (ICH Q2(R2)).

FAQ

Is the HRH-XP2020 compatible with Andersen Cascade Impactors or only NGI systems?
It is mechanically optimized for NGI trays (8-stage configuration); minor custom fixtures may be required for Andersen units due to differing tray geometry and mounting depth.
Can the device be calibrated in-house, or does it require third-party certification?
Angular accuracy verification can be performed using a certified digital inclinometer; full calibration certificate (traceable to NIM, China) is available upon request from authorized service centers.
Does the unit meet electromagnetic compatibility (EMC) standards for laboratory use?
Yes—complies with GB/T 18268.1-2010 (equivalent to IEC 61326-1:2012) for EMC in laboratory environments.
What maintenance is required to sustain long-term positional accuracy?
No routine lubrication or mechanical adjustment is needed; periodic verification of tilt sensor zero-point drift (annually or after 10,000 cycles) is recommended.
Is there a GMP-compliant version with 21 CFR Part 11 audit trail functionality?
Firmware upgrade path to Part 11 mode is available; includes electronic signatures, user role management, and immutable event logging—subject to site-specific validation protocol execution.
