CZGY SHZ-82 Water-Bath Constant-Temperature Orbital Shaker

Overview

The CZGY SHZ-82 Water-Bath Constant-Temperature Orbital Shaker is an integrated laboratory instrument engineered for precise temperature control and uniform orbital agitation of liquid-phase biological and biochemical samples. It operates on the principle of orbital (circular) motion—where the platform rotates around a central axis with fixed amplitude—combined with thermostatically regulated water-bath heating. This configuration ensures gentle yet effective mixing while maintaining thermal homogeneity across the entire sample volume, making it particularly suitable for applications requiring both controlled incubation and mechanical suspension, such as microbial culture propagation, enzyme reaction kinetics, solubility studies, and cell-based assays. Unlike air-jacketed shakers, the water bath provides superior thermal inertia and spatial uniformity, minimizing temperature gradients during extended operation.

Key Features

• Orbital motion mechanism with adjustable speed (0–300 rpm) via analog rotary control, enabling smooth acceleration and stable operation without mechanical overshoot or vibration transmission.
• Digital LED temperature display with real-time feedback and ±0.5 °C stability and uniformity over the full operating range (ambient to 100 °C).
• Stainless steel water bath chamber and platform—electropolished and passivated for long-term corrosion resistance against aqueous buffers, saline solutions, and mild reagents.
• Single-tier platform (40 × 31 cm) with universal spring-loaded clamps compatible with Erlenmeyer flasks (50–2000 mL), test tubes, and multi-well plates using optional adapters.
• Programmable mechanical timer (0–120 minutes) with audible end-of-cycle alert; also supports continuous operation mode for unattended overnight protocols.
• High-efficiency 1500 W heating system with PID-controlled solid-state relay, ensuring rapid thermal equilibration and minimal overshoot during setpoint changes.
• Compact footprint (69 × 46 × 48 cm) and integrated water-level sensor with low-water cutoff protection to prevent dry-heating damage.

Sample Compatibility & Compliance

The SHZ-82 accommodates standard glass and polypropylene labware used in life science workflows—including conical flasks, serum bottles, and deep-well microplates—without compromising thermal transfer or mechanical integrity. Its stainless steel construction meets general laboratory equipment material requirements per ISO 8573-1 (compressed air purity) and complies with IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments. While not certified for GLP/GMP production environments out-of-the-box, its consistent temperature performance and traceable analog controls support documentation of operational parameters for internal SOPs and method validation under ISO/IEC 17025 frameworks. The absence of digital data logging requires manual recording for audit trails; however, external USB thermographs or calibrated PT100 probes may be deployed for third-party verification.

Software & Data Management

The SHZ-82 is a standalone analog-controlled instrument with no embedded firmware, network interface, or proprietary software. All operational parameters—including set temperature, rotational speed, and timer duration—are adjusted manually and displayed locally via front-panel LEDs. This architecture eliminates cybersecurity vulnerabilities, reduces calibration complexity, and ensures long-term operational continuity without dependency on vendor-specific drivers or OS updates. For laboratories requiring electronic data capture, integration with external environmental monitoring systems (e.g., DeltaTrak, Testo, or Omega iChart) is achievable via 4–20 mA or 0–5 V analog output modules (optional add-on). No FDA 21 CFR Part 11 compliance is provided natively; however, paper-based logbooks or validated electronic lab notebooks (ELNs) may be used to satisfy ALCOA+ data integrity principles when paired with operator-signed run records.

Applications

• Microbial cultivation of bacteria, yeast, and fungi under defined thermal and aeration conditions.
• Protein solubilization and buffer exchange during purification workflows.
• Hybridization and washing steps in nucleic acid blotting procedures.
• Standardization of dissolution testing for pharmaceutical excipients in aqueous media.
• Environmental microbiology: enrichment cultures from water or soil extracts.
• Cell suspension maintenance for transient transfection or bioreactor seed train preparation.
• Accelerated stability studies involving temperature-dependent chemical degradation in solution phase.

FAQ

What is the maximum flask size supported on the SHZ-82 platform?
Erlenmeyer flasks up to 2000 mL can be secured using the included universal spring clamps; optimal balance is achieved with vessels ≤1000 mL at speeds >200 rpm.
Can the unit operate without water in the bath?
No—the water bath is integral to thermal regulation and heat dissipation; dry operation will trigger automatic shutdown and may damage the heating element.
Is the temperature sensor externally accessible for calibration verification?
Yes—a 1/4″ NPT port is located on the rear panel for insertion of a reference RTD or thermistor probe during periodic verification.
Does the SHZ-82 support remote start/stop or data export?
No—this is a manually operated analog instrument; all functions require direct front-panel interaction.
What maintenance is recommended for long-term reliability?
Monthly inspection of water bath cleanliness, descaling with 5% acetic acid if hard water is used, and annual verification of thermostat accuracy using a NIST-traceable thermometer.
