BOXUN HH.S11-6 Single-Row Six-Hole Precision Water Bath

Overview

The BOXUN HH.S11-6 is a single-row, six-hole precision water bath engineered for stable thermal conditioning of samples in routine laboratory workflows. It operates on the principle of convective heat transfer via a thermostatically controlled water medium, ensuring uniform temperature distribution across all six independent sample wells. Designed for applications requiring sustained, low-fluctuation thermal environments—such as enzyme incubation, serum warming, reagent equilibration, and dissolution testing—the HH.S11-6 delivers consistent thermal performance within a range of ambient +5 °C to 100 °C. Its stainless-steel inner chamber and electrophoretically coated steel outer housing provide corrosion resistance and mechanical durability under continuous operation. The unit complies with general safety requirements per IEC 61010-1 for laboratory electrical equipment and is constructed to support long-term reliability in QC, clinical pathology, and academic research settings.

Key Features

• Single-row, six-well configuration optimized for parallel sample processing without cross-contamination risk
• High-stability PID temperature control system incorporating platinum resistance sensor (PT100-class equivalent) and low-drift analog circuitry
• ±1 °C temperature accuracy maintained across full operating range, verified at multiple setpoints per ISO/IEC 17025 calibration guidelines
• 18-liter total bath volume ensures sufficient thermal mass for minimal temperature overshoot and rapid recovery after lid opening
• Integrated electronic diagnostics monitor heater continuity, sensor integrity, and power regulation status—alerts displayed via LED indicators
• Front-accessible water level window and drain valve facilitate routine maintenance and fluid replacement
• Non-slip rubber feet and recessed rear cable management enhance benchtop stability and cable safety

Sample Compatibility & Compliance

The HH.S11-6 accommodates standard laboratory glassware including test tubes (up to Ø25 mm), culture bottles, and small-volume beakers placed directly into the six heated wells. Each well accepts vessels up to 120 mm in height and supports immersion depths compatible with common serological and biochemical protocols. The unit meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not certified to GLP or GMP Annex 11 out-of-the-box, its deterministic temperature behavior, diagnostic logging capability, and traceable control architecture enable qualification under internal SOPs aligned with FDA 21 CFR Part 11 data integrity expectations when paired with external validation documentation.

Software & Data Management

The HH.S11-6 operates as a standalone analog-digital hybrid instrument with no embedded microprocessor or network interface. Temperature setpoint and real-time display are managed via a calibrated rotary encoder and dual-digit LED readout. All operational parameters—including setpoint, actual bath temperature, and fault codes—are locally observable but not digitally exportable. For laboratories requiring audit trails or electronic records, integration with external data loggers (e.g., Omega OM-DAQPRO or Testo 176 T4) is supported via optional 4–20 mA or 0–5 V analog output (available on request with OEM firmware revision). Calibration certificates compliant with ISO/IEC 17025 may be supplied upon request, documenting as-found/as-left performance at three points across the operating range.

Applications

• Clinical pathology labs: Warming blood serum, plasma, and CSF specimens prior to immunoassay or coagulation testing
• Pharmaceutical QC: Dissolution media conditioning per USP , gelatin capsule softening studies, and extractive equilibrium
• Microbiology: Pre-incubation of culture media, antibiotic stock solution tempering, and enzymatic reaction initiation
• Academic research: DNA hybridization buffer equilibration, protein denaturation controls, and polymerase chain reaction (PCR) master mix preparation
• Industrial QA: Viscosity reference standard stabilization, coating viscosity adjustment, and adhesive preheating for adhesion testing

FAQ

Does the HH.S11-6 support external temperature probe input for sample-specific monitoring?
No—temperature sensing is fixed to the bath medium only. Optional external probe integration requires factory modification and is not part of the standard configuration.
Is distilled water mandatory for operation?
Deionized or distilled water is strongly recommended to prevent scale buildup on the heating element and sensor surface, particularly when operating above 60 °C for extended periods.
Can the unit be operated continuously for 72 hours or longer?
Yes—the 1.5 kW heating system and thermal insulation design permit uninterrupted operation; however, periodic visual inspection of water level and chamber integrity is advised per preventive maintenance schedules.
What is the maximum recommended fill level for optimal thermal uniformity?
Fill to 10–15 mm below the top rim of the stainless-steel chamber (approximately 16–17 L) to ensure convection circulation and minimize evaporation-related drift.
Is there a built-in timer or auto-shutdown function?
No—this model does not include programmable timing or safety cutoff logic. Users must implement external timers or process supervision protocols where time-critical thermal exposure is required.
