Overview
The HAIDA HD-T011 Toilet Tissue Dispersibility Tester is a purpose-built laboratory instrument engineered to quantitatively evaluate the aqueous dispersibility — i.e., the rate and completeness of physical disintegration under controlled hydraulic shear — of flushable toilet tissue products. Dispersibility is a critical functional parameter for ensuring safe passage through municipal wastewater infrastructure and preventing blockages in residential or commercial plumbing systems. The instrument operates on the principle of standardized hydraulic agitation: a defined volume of distilled or deionized water is circulated at a regulated flow rate through a transparent test chamber containing a pre-weighed tissue sample. The system monitors visual disintegration progress over time, enabling objective assessment of fiber separation, sheet fragmentation, and suspension formation in accordance with internationally referenced test methodologies.
Key Features
- Full-color 7-inch capacitive touchscreen interface with intuitive menu-driven navigation, supporting both English and Chinese language modes for multilingual laboratory environments.
- Precision-engineered imported rotameter (variable-area flowmeter) calibrated for stable, repeatable water flow control across the specified test range — essential for maintaining hydrodynamic consistency between replicates.
- Dedicated 32-bit microcontroller unit (MCU) based on STMicroelectronics’ industrial-grade ARM Cortex-M series architecture, providing high real-time processing capability, low-latency I/O response, and long-term operational reliability.
- Corrosion-resistant stainless steel and borosilicate glass construction ensures chemical compatibility with aqueous media and facilitates full optical observation of dispersion dynamics.
- Integrated timing module with ±0.5 s accuracy enables precise adherence to standard-defined test durations (e.g., 15–300 seconds per cycle).
Sample Compatibility & Compliance
The HD-T011 accommodates standard single-ply and multi-ply toilet tissue specimens (typically 10 cm × 10 cm or as specified in method protocols), including embossed, quilted, lotion-infused, and recycled-fiber variants. It is explicitly validated for conformance with GB/T 20810–2018 “Toilet Tissue”, which defines dispersibility evaluation via visual scoring after fixed-duration agitation. While GB/T 20810 is the primary reference, the instrument’s mechanical and flow-control parameters are compatible with comparative assessments aligned with ASTM D6889 (Standard Test Method for Dispersibility of Flushable Products in Household Toilet Systems) and ISO 17425:2016 (Determination of Disintegration Behavior of Flushable Wipes in Simulated Sewer Conditions), provided appropriate calibration and procedural adaptation are applied. All hardware components meet RoHS Directive 2011/65/EU material restrictions.
Software & Data Management
The embedded firmware supports manual test initiation, real-time flow-rate display, elapsed time tracking, and pass/fail status logging per test cycle. Test records — including date/time stamp, operator ID (via optional login module), flow rate setting, duration, and user-assigned dispersibility grade — are stored internally and exportable via USB flash drive in CSV format. Audit trail functionality complies with basic GLP documentation requirements; full 21 CFR Part 11 compliance (electronic signatures, role-based access control, immutable logs) is available upon request with optional software upgrade and validation package.
Applications
- Quality assurance laboratories evaluating batch-to-batch consistency of toilet tissue dispersibility during routine production release testing.
- R&D departments optimizing pulp blend composition, wet-strength additive dosage, and creping parameters to balance tensile strength versus dispersibility performance.
- Third-party certification bodies conducting conformity assessments for eco-label programs (e.g., EU Ecolabel, Green Seal GS-1) requiring verified flushability data.
- Municipal wastewater treatment authorities validating manufacturer claims regarding sewer-system compatibility of new product formulations.
- Academic research into fiber morphology–hydrodynamics relationships governing disintegration kinetics in turbulent aqueous environments.
FAQ
What standards does the HD-T011 directly support?
It is designed and factory-validated for GB/T 20810–2018; method adaptations for ASTM D6889 and ISO 17425 are feasible with documented procedural adjustments.
Is flow rate adjustable during a test cycle?
No — flow rate is set prior to test initiation and held constant throughout the cycle to ensure hydrodynamic reproducibility per standard requirements.
Can the instrument be integrated into a LIMS environment?
Yes; CSV exports are structured for direct ingestion into common Laboratory Information Management Systems (LIMS); API-level integration requires custom middleware development.
What maintenance is required for long-term accuracy?
Annual verification of rotameter calibration against NIST-traceable flow standards is recommended; routine cleaning of the test chamber and flow path with deionized water prevents residue buildup.
Does HAIDA provide IQ/OQ documentation for GMP-regulated facilities?
Yes — Installation Qualification (IQ) and Operational Qualification (OQ) protocols, executed by certified field service engineers, are available as an add-on service package.
