Tailin HTY-H2 Dedicated Culture Medium Incubation Heater

Overview

The Tailin HTY-H2 Dedicated Culture Medium Incubation Heater is a compact, laboratory-grade thermal management system engineered specifically for the controlled warming and maintenance of sterile culture media in microbiological and pharmaceutical quality control environments. Unlike general-purpose incubators or heating blocks, the HTY-H2 employs a dual-chamber, microprocessor-regulated resistive heating architecture optimized for rapid thermal equilibration and minimal temperature gradient across small-volume media containers (e.g., bottles, flasks, or pouches up to 500 mL). Its design conforms to core principles of thermal stability and sterility preservation—critical for pre-incubation conditioning of agar, broth, or selective media prior to membrane filtration, pour-plate, or spread-plate assays. The unit operates exclusively within the biologically relevant range of 20–65 °C, avoiding unnecessary high-temperature exposure that may degrade heat-labile nutrients or antibiotics commonly incorporated into diagnostic or regulatory-compliant media formulations.

Key Features

• Dual independent heating chambers enable selective activation of left or right compartment—ideal for parallel processing of different media types or staggered workflow scheduling without cross-contamination risk.
• Two operational modes: dry conductive heating for rapid warm-up of sealed containers; or water-bath mode (with optional stainless-steel water pan) for uniform, gentle thermal transfer—minimizing evaporation and thermal shock to sensitive formulations.
• Embedded microprocessor controller with LED display ensures ±0.5 °C temperature stability under steady-state conditions and supports programmable setpoint retention during power interruption (non-volatile memory).
• Corrosion-resistant 304 stainless steel housing and heating chamber provide long-term durability in humid or disinfectant-exposed lab environments, complying with ISO 14644-1 Class 8 cleanroom-compatible surface requirements.
• Compact footprint (37.5 × 28 × 16 cm) and low mass (7 kg) facilitate placement on biosafety cabinets, laminar flow hoods, or QC benchtops without compromising workspace ergonomics or airflow integrity.

Sample Compatibility & Compliance

The HTY-H2 accommodates standard microbiological containers including glass or PETG media bottles (up to Ø12.5 cm diameter), screw-cap flasks, and pre-filled sterile pouches. Its chamber geometry supports upright positioning of containers with minimal tilting—ensuring consistent heat distribution and preventing sedimentation or phase separation in enriched or selective media. The device meets essential electrical safety requirements per GB 4793.1–2019 (equivalent to IEC 61010-1) and is suitable for use in GLP-compliant laboratories conducting media growth promotion testing per USP , , and EP 2.6.12. While not a regulated medical device, its thermal performance characteristics align with internal SOPs for media preparation validation as referenced in ISO 11133:2014 (Microbiology of food and animal feeding stuffs — Guidance on the preparation and production of culture media).

Software & Data Management

The HTY-H2 operates via an embedded real-time controller without external software dependency. All temperature settings, active chamber selection, and operational mode are managed locally through tactile keypad input and visual LED feedback. No data logging, USB export, or network connectivity is provided—consistent with its role as a dedicated, low-risk auxiliary heater rather than a fully validated environmental chamber. For laboratories requiring audit-ready thermal records, integration with external calibrated data loggers (e.g., compliant with FDA 21 CFR Part 11 via third-party validation packages) is supported through analog output options (available upon request with custom configuration). Routine calibration verification can be performed using NIST-traceable PT100 probes inserted directly into the chamber during operation.

Applications

• Pre-warming of molten agar prior to pour-plating in environmental monitoring or pharmaceutical water system testing.
• Temperature conditioning of buffered peptone water, tryptic soy broth, or Rappaport-Vassiliadis medium for standardized microbial recovery assays.
• Holding of prepared media at specified temperatures (e.g., 45 ± 1 °C for pour plates; 30–35 °C for enrichment broths) during extended QC shift windows.
• Supporting ISO 13408-2 (Aseptic processing of health care products) Annex C protocols where controlled thermal delivery of media to isolators or restricted access barrier systems (RABS) is required.
• Facilitating media fill simulations by maintaining sterility-critical temperature profiles during simulated aseptic transfers.

FAQ

Is the HTY-H2 suitable for sterilization or depyrogenation?
No. This unit is strictly a temperature-controlled incubation/heating device—not a sterilizer, autoclave, or dry-heat oven. It does not achieve temperatures or dwell times required for microbial kill or endotoxin inactivation.
Can it maintain temperature accuracy under continuous door-opening conditions?
The HTY-H2 is designed for closed-chamber operation. Frequent or prolonged chamber access will result in measurable thermal lag and overshoot; optimal performance requires minimal intervention once setpoint is reached.
Does it support protocol-based automated cycling (e.g., ramp-hold-cool sequences)?
No. The controller supports only static setpoint operation. Multi-step thermal profiles require external programmable logic controllers or integrated lab automation platforms.
What maintenance is required for long-term reliability?
Routine cleaning of stainless surfaces with 70% ethanol or isopropyl alcohol; annual verification of temperature uniformity using calibrated thermocouples at three axial positions within each chamber.
Is CE or UKCA marking available?
The standard HTY-H2 configuration is certified to CCC (China Compulsory Certification) and complies with GB standards. CE/UKCA versions are available subject to regional conformity assessment and additional EMC/safety testing—contact Tailin Biotechnology’s international sales division for documentation and lead time details.
