Overview
The HAIDA HD-D003 Tampon Absorbency Tester is a precision-engineered laboratory instrument designed to quantitatively evaluate the fluid absorption capacity of tampons under standardized, physiologically relevant conditions. It operates on the gravimetric principle: a defined volume of synthetic vaginal fluid—typically saline solution buffered to pH 4.2–4.5—is delivered at a controlled, constant flow rate onto a vertically suspended tampon specimen using a calibrated peristaltic pump. The device measures the mass difference before and after absorption, expressed in grams (g), thereby delivering a repeatable, traceable metric for absorbency performance. This methodology directly aligns with the hydrodynamic simulation requirements specified in TCNITA 09102–2018 Annex E—the primary Chinese national technical standard governing tampon safety and functional testing. As such, the HD-D003 serves as a critical quality control tool for manufacturers, contract laboratories, and regulatory validation units operating within hygiene product R&D, production release, and post-market surveillance frameworks.
Key Features
- Full-color 7-inch capacitive touchscreen interface with intuitive menu-driven navigation, supporting both English and Chinese language modes for multilingual operational flexibility.
- Real-time digital display of elapsed test duration during absorption cycles, enabling precise timing adjustments to meet protocol-specific exposure windows (e.g., 5 min, 10 min, or user-defined intervals).
- Embedded 32-bit microcontroller platform based on STMicroelectronics’ industrial-grade ARM Cortex-M series architecture, ensuring deterministic real-time response, low-latency I/O handling, and long-term firmware stability.
- High-precision peristaltic pump system with silicone tubing and adjustable RPM control, delivering consistent volumetric delivery rates (±1.5% repeatability over 100 mL/h range) without pulsation or backflow—critical for simulating natural fluid ingress dynamics.
- Integrated sample holder assembly with vertical orientation fixture, compliant with TCNITA 09102–2018 geometric constraints for tampon suspension and drip zone alignment.
- Stainless-steel chassis with anti-corrosion coating and modular design for easy cleaning, calibration access, and routine maintenance in GLP-compliant lab environments.
Sample Compatibility & Compliance
The HD-D003 accommodates standard commercial tampon formats—including applicator and non-applicator types—within nominal dimensions of Ø12–18 mm × L45–65 mm. Specimen mounting fixtures are interchangeable to support both string-attached and integrated withdrawal cord configurations. All mechanical and fluidic parameters adhere strictly to TCNITA 09102–2018 Annex E, which defines drop height (25 ± 2 mm), fluid temperature (37 ± 1 °C), flow rate (1.0 ± 0.1 mL/min), and environmental conditioning (23 ± 2 °C / 50 ± 5% RH prior to testing). While not certified to ISO 13485 or FDA 21 CFR Part 820 out-of-the-box, the system’s design enables full traceability documentation (test logs, operator ID, timestamped mass readings) required for internal audit readiness and third-party certification pathways.
Software & Data Management
The embedded firmware supports local data storage of up to 500 test records, each containing pre-test mass, post-test mass, net absorbency value, test duration, ambient temperature/humidity (via optional external sensor input), and operator ID. Data export is available via USB 2.0 port in CSV format for downstream statistical analysis in Excel, Minitab, or LIMS platforms. Audit trail functionality includes automatic timestamping and immutable record generation—supporting basic GLP documentation requirements. Optional PC-based companion software (HAIDA TestSuite v2.1) provides enhanced visualization, batch reporting, trend charting, and comparative analysis across multiple lots or formulations.
Applications
- Quality assurance of finished tampon products prior to packaging and distribution.
- Raw material evaluation (e.g., rayon vs. cotton vs. blended fibers) for absorbency optimization during formulation development.
- Process validation of manufacturing steps affecting density, compression, or surface treatment.
- Comparative benchmarking against competitive products under identical test conditions.
- Supporting technical dossiers for domestic registration (NMPA Class I/II medical devices) and export documentation (ASEAN, GCC, Latin America).
- Academic research in textile science, biomaterials engineering, and women’s health product design.
FAQ
What synthetic fluid is recommended for testing?
Physiological saline (0.9% NaCl, pH-adjusted to 4.2–4.5 with lactic acid) per TCNITA 09102–2018 Annex E; alternative fluids require method validation.
Is temperature control built into the system?
No—external water bath or incubator is required to maintain fluid at 37 ± 1 °C; the HD-D003 includes thermal insulation sleeves for tubing and drip nozzle.
Can the HD-D003 be integrated into an automated QC line?
Not natively; it is a benchtop standalone unit. However, its USB-CDC serial interface supports custom SCADA integration via Modbus RTU emulation (firmware upgrade required).
Does the system include calibration certificates?
Yes—NIST-traceable calibration report for the integrated analytical balance (0.001 g resolution) is provided upon shipment; annual recalibration is recommended.
What maintenance is required for the peristaltic pump?
Silicone tubing must be replaced every 500 operational hours or when visible cracking/elasticity loss occurs; pump head alignment verification is advised quarterly.
