Tailin HTY-QTS01 Programmable Quantitative Sealer

Overview

The Tailin HTY-QTS01 Programmable Quantitative Sealer is an engineered solution for standardized, high-throughput microbial enumeration in water quality laboratories. Designed specifically for use with Quanti-Tray®-compatible multi-well trays (51- and 97-well formats), the instrument applies precisely controlled thermal sealing pressure to hermetically seal inoculated wells—enabling simultaneous quantitative and qualitative detection of target microorganisms via the Most Probable Number (MPN) method. Its operational principle relies on uniform heat transfer and pneumatic compression across the tray surface, ensuring reproducible seal integrity without deformation or cross-contamination between wells. The HTY-QTS01 supports regulatory-compliant workflows aligned with standard methods including ISO 9308-1 (E. coli and coliforms in water), EPA Method 1604 (total coliforms and E. coli), and ASTM D5465 (microbial enumeration by MPN). It is routinely deployed in municipal drinking water facilities, environmental monitoring agencies, food and beverage production QA/QC labs, and third-party certification laboratories requiring GLP-aligned data traceability.

Key Features

• Programmable sealing parameters—including temperature ramp profile, dwell time, and pressure calibration—ensuring batch-to-batch consistency across diverse tray materials and ambient conditions.
• Dual-mode operation: validated for both sterile laminar flow hoods and non-sterile benchtop environments, minimizing infrastructure dependency while maintaining assay integrity.
• Integrated real-time sealing counter with digital display; automatically increments per completed tray, supporting audit-ready usage logs.
• Thermally optimized heating plate with uniform surface temperature distribution (<±2 °C deviation across active area), eliminating hot spots that cause over-sealing or incomplete fusion.
• Front-mounted maintenance access door facilitating rapid removal of sealing gaskets, tray alignment guides, and thermal sensors for routine calibration verification and residue clearance.
• Acoustically damped enclosure meeting ISO 7779 noise emission standards, with measured sound pressure <50 dB(A) at 1 m distance—suitable for shared laboratory spaces.

Sample Compatibility & Compliance

The HTY-QTS01 is validated for use with commercially available 51-well and 97-well quantification trays pre-filled with selective chromogenic/fluorogenic media (e.g., Colilert®, Enterolert®, Legiolert®). It accommodates standard tray dimensions (127 × 86 mm) and thickness tolerances (2.8–3.2 mm). All sealing protocols are compatible with USP /, ISO 11731-2, and EN ISO 9308-1 requirements for membrane filtration and MPN-based enumeration. The device’s mechanical design conforms to IEC 61010-1 safety standards for electrical equipment used in laboratory environments. No modifications to tray geometry or reagent formulation are required to achieve full compliance with EPA-approved test methods.

Software & Data Management

While the HTY-QTS01 operates as a standalone hardware platform without embedded firmware-based data storage, its deterministic sealing output integrates seamlessly into LIMS and ELN ecosystems via manual entry or barcode-scanned tray ID logging. Each sealed tray carries a unique well-pattern signature corresponding to the MPN table included with the unit (provided in printed laminated format and PDF). For laboratories implementing 21 CFR Part 11 compliance, external electronic records may be generated using validated spreadsheet templates or commercial microbiology data management software (e.g., Thermo Fisher SampleManager, LabVantage Microbiology Module). Audit trails, user access controls, and electronic signatures are managed externally—consistent with GxP-aligned documentation practices.

Applications

• Routine monitoring of drinking water distribution systems for total coliforms, E. coli, and enterococci per regulatory reporting cycles.
• Validation of point-of-use water filters and UV disinfection units via challenge testing with defined microbial suspensions.
• Environmental surveillance in healthcare settings targeting Legionella pneumophila in cooling towers and potable water networks.
• Recreational water quality assessment (pools, spas, lakes) under national bathing water directives.
• Raw water intake screening at wastewater treatment plants to inform coagulation and disinfection dosing strategies.
• Contract laboratory support for ISO/IEC 17025-accredited testing services requiring documented sealing repeatability and inter-laboratory comparability.

FAQ

Is the HTY-QTS01 compatible with non-Tailin branded trays?
Yes—provided trays conform dimensionally and thermally to ASTM D5465 specifications and utilize polypropylene or polystyrene substrates with standard sealing temperature thresholds (120–140 °C). Compatibility validation is recommended prior to routine use.
Does the instrument require annual calibration?
Per ISO/IEC 17025 Clause 6.5.2, users must verify thermal uniformity and pressure delivery at least annually—or after any major maintenance—using NIST-traceable surface thermometers and calibrated load cells.
Can it be operated inside a biosafety cabinet?
Yes. Its compact footprint, low heat dissipation (<40 °C housing), and absence of forced-air cooling make it suitable for Class II A2 cabinet integration without airflow disruption.
What is the expected lifetime of the sealing gasket?
Under normal use (≤50 trays/day), the supplied silicone gasket maintains dimensional stability and compression recovery for ≥12 months; replacement kits are available with lot-specific QC certificates.
Is remote diagnostics supported?
No. The HTY-QTS01 contains no network interface or telemetry capability. All operational status indicators are local (LEDs, audible tone, tactile feedback).
