Tailin HTY-QTS02L Portable Vehicle-Mounted Programmable Quantitative Sealer

Overview

The Tailin HTY-QTS02L is a portable, vehicle-mounted programmable quantitative sealer engineered for field-deployable microbiological water quality testing—specifically designed to support standardized membrane filtration and IDEXX-defined Colilert®/Enterolert®-based quantification workflows. It operates on the principle of thermoplastic sealing: applying precisely controlled heat and pressure to hermetically seal IDEXX Quanti-Tray® or Quanti-Tray/2000® wells after sample inoculation, thereby enabling subsequent incubation and fluorescent colony enumeration. Unlike benchtop sealers, the HTY-QTS02L integrates structural and thermal optimizations for mobile deployment—featuring rapid thermal response, low standby power draw, and mechanical stability under vibration conditions typical of light-duty vehicles (e.g., environmental survey vans, municipal water response units). Its design complies with the functional requirements outlined in Standard Methods for the Examination of Water and Wastewater (2022 Edition, Method 9223B) for tray-based quantification systems.

Key Features

• Compact vehicle-mountable form factor (W × D × H: 320 × 260 × 180 mm), equipped with integrated ergonomic carry handle and anti-slip rubber feet for stable operation on uneven surfaces
• High-reproducibility heating module using low-wattage tubular heating elements with PID-controlled temperature regulation (±1.5 °C accuracy across 120–180 °C range)
• Programmable sealing cycle with adjustable dwell time (1–12 s) and dual-stage pressure actuation to ensure uniform well deformation without tray warping
• Thermally insulated polypropylene composite housing that maintains external surface temperature below 45 °C during continuous operation—critical for safe handling in high-ambient outdoor environments
• Universal AC input compatibility (220 V ±10 %, 50 Hz) with optional DC-AC inverter support (12 V/24 V input), enabling direct integration with vehicle auxiliary power systems
• Embedded self-diagnostic firmware with LED status indicators for heater readiness, seal completion, and thermal fault detection

Sample Compatibility & Compliance

The HTY-QTS02L is validated for use with IDEXX Quanti-Tray®, Quanti-Tray/2000®, and compatible third-party trays conforming to ASTM D5392-21 specifications for sealed multi-well quantification devices. It supports standard 100-mL and 10-mL sample volumes as defined in EPA Method 1604 and ISO 9308-1:2014. The sealer’s output meets the minimum seal integrity threshold required for ≥95 % fluorescence retention during 24–48 h incubation at 35 ±0.5 °C (per IDEXX technical validation protocol TR-2021-004). Units are manufactured under ISO 13485-certified quality management systems; CE marking is pending final EU MDR alignment. No regulatory claim is made for FDA 510(k) clearance or Health Canada Medical Device License, as the device functions solely as a non-invasive sample containment tool—not an in vitro diagnostic instrument.

Software & Data Management

The HTY-QTS02L operates as a standalone electromechanical system with no embedded software, cloud connectivity, or data logging capability—consistent with field instrumentation design principles prioritizing reliability, electromagnetic immunity, and minimal maintenance. All operational parameters (seal duration, target temperature, cycle count) are set via tactile rotary encoder and confirmed via dual-color LED display. This architecture eliminates firmware vulnerabilities, ensures uninterrupted function in RF-noisy environments (e.g., near radio transceivers or GPS units), and satisfies audit requirements for GLP-compliant field labs where traceability is maintained through handwritten or tablet-based logbooks referencing batch-specific seal verification records.

Applications

• Rapid-response microbial monitoring of drinking water distribution systems during emergency events (e.g., post-flooding, pipe break investigations)
• Regulatory compliance sampling for total coliform and E. coli enumeration in remote rural water supplies lacking fixed laboratory infrastructure
• Field validation of point-of-use (POU) filter performance using paired pre-/post-filter Quanti-Tray assays
• Environmental health surveys in developing regions where grid power is intermittent or unavailable—enabled by inverter-compatible DC operation
• Academic field courses in environmental microbiology requiring transportable, student-safe quantification hardware

FAQ

Can the HTY-QTS02L be used with non-IDEXX trays?
Yes—provided the tray geometry matches Quanti-Tray® dimensions (100 mm × 100 mm footprint, 13.5 mm well depth) and the lid material exhibits comparable thermal bonding characteristics (e.g., polystyrene lids with 120–160 °C melt onset). Validation of seal integrity is the user’s responsibility.
Is calibration required before each use?
No routine calibration is specified. However, users must perform a daily visual inspection of the sealing bar for debris and verify consistent seal appearance across 3 consecutive test trays using control samples. A temperature verification log is recommended per ISO/IEC 17025:2017 Clause 7.8.2.
What maintenance does the unit require?
Monthly cleaning of the sealing bar with lint-free isopropyl alcohol swabs; annual inspection of heater element resistance (target: 108 ±5 Ω at 25 °C) using a calibrated multimeter. No lubrication or consumable parts are required.
