Overview
The SHZ-82(A) Water-Bath Constant-Temperature Orbital Shaker is an engineered platform for precise, reproducible incubation and agitation of biological samples under controlled thermal and mechanical conditions. Designed for laboratory environments requiring simultaneous temperature stability and uniform reciprocal oscillation, this instrument employs a water-bath heating system—providing superior thermal homogeneity compared to air-based alternatives—combined with a robust electromagnetic drive mechanism that delivers consistent linear motion across the entire platform. Its operational principle relies on conductive heat transfer through deionized or distilled water, maintaining setpoint accuracy within ±0.5 °C across the working chamber, while the oscillation frequency is digitally regulated and continuously monitored to ensure process repeatability in sensitive microbiological and cell culture workflows.
Key Features
- Water-bath thermal regulation with PID-controlled heating element, enabling stable operation from ambient temperature up to 100 °C
- Digital LED display showing real-time bath temperature and oscillation speed (rpm), with adjustable resolution of 1 rpm
- Reciprocal (linear) oscillation mode optimized for suspension cultures, microbial growth assays, and enzymatic reaction kinetics
- Stainless-steel water tank with anti-corrosion coating and over-temperature protection circuitry compliant with IEC 61010-1 safety standards
- Detachable platform accommodating standard-sized flasks (up to 2 L), test tubes, and multi-well plates via universal clamping accessories
- Low-noise DC motor with brushless design ensures long-term reliability and minimal vibration transmission to adjacent instrumentation
Sample Compatibility & Compliance
The SHZ-82(A) supports aqueous-phase sample containers ranging from 15 mL centrifuge tubes to 2 L Erlenmeyer flasks, making it suitable for bacterial culture expansion (e.g., E. coli, Bacillus subtilis), yeast fermentation studies, antigen-antibody binding assays, and tissue dissociation protocols. It conforms to national standard GB/T 26571–2011 for laboratory water-bath shakers and is compatible with GLP and GMP-aligned workflows when integrated into documented SOPs. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its digital logging capability (via optional RS-232 interface) supports audit-trail generation for regulated environments upon configuration with validated third-party data acquisition software.
Software & Data Management
The unit operates as a standalone analog-digital hybrid system with no embedded firmware or cloud connectivity. All control logic resides in hardware-level microcontroller architecture, minimizing cybersecurity exposure and ensuring deterministic response during extended incubation cycles (up to 999 hours). Temperature and speed settings are retained after power interruption, and the device logs no internal history; however, external recording is facilitated via analog voltage output (0–5 V) proportional to rpm and PT100-compatible terminals for integration with programmable logic controllers (PLCs) or SCADA systems. For laboratories requiring electronic records, connection to a time-stamped data logger or LIMS-compatible DAQ module enables full traceability per ALCOA+ principles.

- Environmental monitoring: enrichment cultures for coliform detection in water safety analysis (APHA Standard Methods 9221)
- Bioremediation research: kinetic assessment of hydrocarbon-degrading consortia under aerobic submerged conditions
- Academic teaching labs: hands-on instruction in microbial growth dynamics, Monod kinetics, and thermal sensitivity profiling
FAQ
What is the maximum load capacity of the platform?
The platform supports a total mass of up to 15 kg when evenly distributed, with optimal performance observed at ≤10 kg for sustained operation at 180 rpm.
Can the unit be used with corrosive solutions such as acidic or alkaline media?
Direct immersion of non-glassware containers containing aggressive chemicals is not recommended. Use only borosilicate glass, polypropylene, or PTFE-lined vessels; avoid prolonged contact between bath water and stainless-steel components exposed to halide-containing solutions.
Is calibration documentation provided with the instrument?
A factory-issued calibration certificate (traceable to NIM, China) covering temperature and speed verification is available upon request and may be included in the shipment documentation package.
Does the shaker support continuous operation for >72 hours?
Yes—the device is rated for uninterrupted duty cycles up to 999 hours, subject to ambient room temperature ≤30 °C and relative humidity <80% RH non-condensing.
How is temperature uniformity verified across the bath volume?
Uniformity is validated using nine-point mapping per GB/T 26571–2011: three vertical layers (top/mid/bottom) × three horizontal positions (center/periphery), measured with calibrated PT100 probes prior to出厂 inspection.
