HengAo HWT-10C Water Bath Shaker

Overview

The HengAo HWT-10C Water Bath Shaker is an integrated laboratory instrument engineered for precise temperature-controlled agitation of liquid samples in glass or plastic vessels. It operates on the principle of orbital or linear oscillation within a thermostatically regulated water bath environment—enabling uniform heat transfer via convection while maintaining mechanical mixing integrity. Designed for routine applications in molecular biology, microbiology, biochemistry, and cell culture workflows, the HWT-10C supports reproducible incubation of enzymatic reactions, bacterial growth assays, solubility studies, and sample homogenization under controlled thermal conditions. Its dual-function architecture—combining shaking and static water bath operation—provides operational flexibility without requiring separate equipment, reducing footprint and cross-contamination risk in shared lab environments.

Key Features

• Brushless DC motor drive ensures low-noise, maintenance-free operation with extended service life and consistent torque delivery across the full 10–200 rpm range.
• PTC ceramic heating elements paired with flexible silicone rubber heating belts deliver rapid, uniform thermal response and inherent overheat protection.
• Microprocessor-based PID temperature controller with LED digital display enables setpoint accuracy of ±0.3 °C and temperature uniformity of ±0.5 °C across the 10 L bath volume.
• All wetted surfaces—including tank interior, platform frame, and lid contact zones—are fabricated from ASTM A240 Type 304 stainless steel, ensuring long-term resistance to corrosion from aqueous buffers, saline solutions, and mild chemical reagents.
• V-shaped insulated lid minimizes condensation accumulation and prevents droplet formation that could compromise sterility or interfere with vessel sealing during extended incubations.
• Modular platform design allows complete removal of the shaking assembly, converting the unit into a high-stability static water bath for applications requiring only thermal equilibration—e.g., enzyme denaturation controls or reagent pre-warming.

Sample Compatibility & Compliance

The HWT-10C accommodates standard laboratory vessels including Erlenmeyer flasks (up to 2 L), test tubes (13–25 mm diameter), centrifuge tubes, and multi-well plates when mounted on optional adapters. Its open-bath configuration supports custom rack integration for non-standard container geometries. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, the instrument’s hardware architecture—including non-volatile parameter storage, stable thermal profiling, and mechanical traceability of oscillation settings—supports GLP-compliant documentation when integrated into validated laboratory workflows. It meets general safety requirements per IEC 61010-1:2010 for electrical equipment used in laboratory environments.

Software & Data Management

The HWT-10C operates via embedded firmware with no external PC dependency. All operational parameters—including temperature setpoint, oscillation speed, and runtime—are stored in non-volatile memory and retained after power cycling. Though it lacks USB or Ethernet connectivity, its LED interface provides real-time feedback on actual vs. set temperature, current rpm, and system status indicators (e.g., heating active, motor engaged, overtemperature alert). For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, manual logging of instrument settings and batch metadata remains compatible with ISO 15189 and CLIA-aligned quality management systems.

Applications

• Microbial culture expansion under defined aeration and thermal conditions
• Protein solubilization and aggregation studies requiring simultaneous heating and gentle agitation
• Hybridization and washing steps in nucleic acid purification protocols
• Standardization of dissolution testing for pharmaceutical excipients
• Cell suspension maintenance during transfection or passaging procedures
• Calibration of temperature-sensitive biosensors using reference standards in aqueous media

FAQ

Can the HWT-10C operate without the shaking function?
Yes—the oscillation platform is fully removable, allowing the unit to function as a precision water bath with ±0.3 °C setpoint accuracy.
What is the maximum flask size supported on the standard platform?
The platform accommodates up to two 2 L Erlenmeyer flasks or eight 500 mL flasks using standard clamping fixtures.
Is the temperature uniformity verified across the entire bath volume?
Yes—calibration data confirms ≤ ±0.5 °C deviation at five spatial points (center, corners, and mid-height) under steady-state conditions at 37 °C and 60 °C.
Does the unit include overtemperature or dry-run protection?
It features dual redundant thermal cutoffs: one integrated into the PTC heater and a separate bimetallic safety thermostat rated at 105 °C.
Are replacement parts such as the V-lid or platform available separately?
Yes—HengAo supplies OEM-certified spare components including stainless steel platforms, silicone gaskets, and V-lid assemblies under part numbers HWT-PLT-01, HWT-GSK-02, and HWT-LID-V10 respectively.
