Tailin HTY-APL Advanced Intelligent Microbial Collection System

Overview

The Tailin HTY-APL Advanced Intelligent Microbial Collection System is an engineered solution for membrane filtration-based sterility testing in pharmaceutical, biotechnology, and contract manufacturing organizations (CMOs). Designed in strict alignment with the principles of USP <71>, EP 2.6.1, and JP 4.07, the system implements a controlled, positive-pressure vacuum-assisted filtration process to isolate viable microorganisms from liquid or soluble solid preparations onto sterile, low-protein-binding membranes. Its core architecture centers on a brushless DC motor-driven peristaltic pump with closed-loop rotational feedback, enabling precise volumetric flow control across variable viscosity and particulate load conditions—critical when processing challenging samples such as suspensions, ophthalmic solutions, lipid emulsions, or highly viscous biologics.

Key Features

• Linear Pump Tube Installation: Eliminates torsional stress during loading; ensures consistent occlusion geometry and reduces tube fatigue over repeated cycles.
• Real-Time Pressure Monitoring & Adaptive Response: Integrated pressure transducer continuously measures backpressure at the filter housing interface. In Alarm + Auto-Regulation mode, the system dynamically reduces rotational speed upon detecting elevated resistance—preventing membrane rupture or sample bypass while maintaining filtration integrity.
• Motorized Automatic Tube Clamping: Electro-mechanical clamp engages before and after filtration to seal the fluid path, minimizing operator-induced variability and supporting unattended operation sequences.
• Digital Pulse Rotary Knob & Tempered Glass Touch Panel: Enables tactile, non-contact parameter adjustment with haptic feedback; supports glove-compatible operation in ISO Class 5 environments.
• Four-Layer Electrical Protection Architecture: Independently monitored overcurrent, overvoltage, overload, and stall detection circuits ensure operational continuity and prevent hardware degradation under transient load conditions.
• IP67-Rated Footswitch Interface: Enables hands-free start/stop control without compromising cleanroom integrity or introducing contamination risk via surface contact.

Sample Compatibility & Compliance

The HTY-APL accommodates standard 47-mm and 50-mm diameter sterile filter membranes (e.g., mixed cellulose ester, PVDF, PES), compatible with commercially available filtration manifolds meeting ASTM F838-22 requirements for bacterial retention validation. It supports both direct filtration and rinse-and-filter protocols per USP <71> Annex. The system’s mechanical design conforms to IEC 61010-1:2010 safety standards for laboratory equipment. All firmware logic paths are traceable for GLP/GMP audit readiness, and the device supports optional electronic logbook integration compliant with FDA 21 CFR Part 11 requirements when paired with validated LIMS interfaces.

Software & Data Management

While the HTY-APL operates as a standalone instrument with embedded firmware, its RS-485 and optional USB-C communication ports enable bidirectional data exchange with external laboratory information management systems (LIMS) or electronic batch record (EBR) platforms. Critical operational parameters—including start time, end time, total filtered volume (calculated from speed/time integral), applied pressure trend, and fault event logs—are timestamped and stored locally for ≥1,000 cycles. Audit trail functionality records user ID, parameter changes, and system status transitions, fulfilling ALCOA+ data integrity criteria for regulated environments.

Applications

• Sterility testing of injectables, ophthalmic preparations, and lyophilized products per pharmacopoeial methods
• Environmental monitoring sample concentration (e.g., water for injection, cleanroom rinse water)
• Bioburden assessment of raw materials and intermediates in API synthesis
• Validation of sterilizing-grade filters using challenge organisms (e.g., Brevundimonas diminuta)
• Supporting compendial method transfers between QC laboratories under ICH Q5C and Q7 guidance

FAQ

Is the HTY-APL suitable for use with viscous or particle-laden formulations?
Yes—the pressure-adaptive speed regulation and linear tube mounting design maintain consistent flow profiles across viscosities up to 25 cP and suspended solids concentrations ≤0.5% w/v, provided appropriate membrane pore size and pre-filtration are applied.

Does the system support IQ/OQ/PQ documentation packages?
Tailin provides standardized qualification templates aligned with ASTM E2500-22 and ISPE GAMP 5, including test protocols, acceptance criteria, and blank execution records for installation, operational, and performance qualification.

Can the HTY-APL be integrated into a fully automated sterility testing workflow?
Yes—via Modbus RTU over RS-485, it interoperates with robotic liquid handlers and automated incubation systems, enabling synchronized start triggers, status polling, and error reporting within integrated validation frameworks.
