Tailin HTY-BWS02 Closed-System Vacuum Sampling Instrument for Bottled Water Microbial Testing

Overview

The Tailin HTY-BWS02 is a purpose-engineered, closed-system vacuum sampling instrument designed specifically for microbiological quality control in the bottled water industry. It operates on the principle of controlled negative-pressure filtration: a calibrated vacuum draws water from sealed polyethylene terephthalate (PET) or polycarbonate containers through a sterile, single-use tubing path directly into a designated collection vessel—typically a 100 mL or 250 mL sterile sampling bottle compliant with ISO 8573-7 and ASTM D5127. Critically, the system incorporates an integrated, hydrophobic air-equilibration filter (0.2 µm PTFE membrane) that allows ambient air to passively replenish the headspace of the source container during withdrawal. This prevents vacuum collapse, container deformation, and potential backflow contamination—key failure modes observed in open or non-vented manual sampling methods. The HTY-BWS02 eliminates the need for bottle inversion, manual pouring, or exposure to ambient laboratory air, thereby minimizing particulate ingress and microbial cross-contamination risk throughout the sampling sequence.

Key Features

• Fully enclosed, single-pass fluid pathway from source container to collection vessel—no intermediate handling or atmospheric exposure
• Patented sterile piercing port interface enables rapid, aseptic penetration of common PET cap seals without cap removal or surface wiping
• Programmable digital timer with adjustable sampling duration (1–120 seconds) for precise volume control across varying container sizes (3–20 L)
• Integrated rechargeable 5600 mAh lithium-ion battery supports ≥80 consecutive sampling cycles per charge—ideal for mobile QC audits or production-line deployment
• IPX4-rated enclosure provides protection against water splashes during wet-environment operation (e.g., bottling line floors, wash-down zones)
• Compact footprint (22.0 × 20.0 × 14.0 cm) and lightweight chassis (3.0 kg) facilitate transport between filling stations, storage coolers, and microbiology labs
• Low-power 30 W motor ensures stable vacuum generation without thermal drift or audible interference in noise-sensitive cleanroom-adjacent areas

Sample Compatibility & Compliance

The HTY-BWS02 accommodates standard commercial bottled water formats—including 3 L, 5 L, 12 L, and 19 L containers—with uniform sampling integrity across all volumes. Its piercing mechanism is validated for use with FDA-compliant PET caps featuring tamper-evident seals and aluminum foil liners. All wetted components—including silicone suction tubing, stainless-steel piercing needle, and vent filter housing—are autoclavable or compatible with 70% ethanol disinfection. The instrument supports adherence to ISO 19001:2015 (quality management), ISO/IEC 17025:2017 (testing laboratory competence), and China’s GB 19298-2014 (Packaged Drinking Water Standard). When operated within defined procedural controls, data generated using the HTY-BWS02 meets evidentiary requirements for GLP-compliant environmental monitoring records.

Software & Data Management

The HTY-BWS02 operates via embedded firmware with no external software dependency. All operational parameters—including date/time stamp, sampling duration, and cycle count—are stored in non-volatile memory and accessible via USB-C interface for audit log export (CSV format). Timestamped logs include operator ID field entry capability, supporting traceability under GMP Annex 11 and FDA 21 CFR Part 11 when integrated into enterprise-quality management systems (QMS). No cloud connectivity or remote access functionality is included—ensuring data sovereignty and alignment with industrial cybersecurity best practices for regulated manufacturing environments.

Applications

• Routine batch release testing of finished bottled water products prior to distribution
• Environmental monitoring of filler nozzles, capping heads, and conveyor surfaces via rinse-water sampling
• Investigation of microbial excursions by enabling rapid, repeatable re-sampling from retained stability units
• Validation of sanitation efficacy during CIP/SIP cycles in water-for-injection (WFI) satellite systems
• On-site auditing of contract manufacturers where portable, battery-powered sampling is required
• Training laboratories simulating aseptic technique workflows for QC technician certification

FAQ

Does the HTY-BWS02 require compressed air or external vacuum sources?

No—it integrates a brushless DC vacuum pump powered exclusively by its internal lithium-ion battery.
Can the piercing port be used with aluminum-sealed glass carboys?

No—the patented port is dimensionally optimized for standard PET and polycarbonate bottle caps; glass containers with screw-threaded metal lids are not supported.
Is the tubing path sterilizable between uses?

Yes—silicone tubing may be autoclaved at 121 °C for 15 minutes or chemically disinfected with 70% ethanol; replacement kits are available as consumables.
What regulatory documentation accompanies the instrument?

Each unit ships with a Factory Calibration Certificate, CE Declaration of Conformity (for EMC and Low Voltage Directive), and ISO 13485-compliant design history file summary.
How is sample volume accuracy verified?

Volume is inferred from empirically derived time–flow curves established during factory validation using gravimetric measurement against NIST-traceable balances; users may perform periodic verification using pre-weighed collection bottles.
