CZGY SHY-3 Water-Bath Constant-Temperature Orbital Shaker

Overview

The CZGY SHY-3 Water-Bath Constant-Temperature Orbital Shaker integrates precise temperature control with consistent orbital agitation in a single benchtop platform. Engineered for reproducible incubation and suspension-based culture protocols, it operates on the principle of orbital shaking—generating uniform circular motion (20 mm amplitude) within a thermostatically regulated water bath environment. This configuration ensures minimal shear stress while maintaining homogeneous thermal distribution across samples, making it particularly suitable for applications requiring both controlled thermal conditions and gentle mixing—such as microbial growth, enzyme reaction kinetics, solubility studies, and cell suspension maintenance. Unlike air-jacketed shakers, the water-bath design delivers superior temperature uniformity and stability (±0.5 °C), critical for sensitive biological assays where thermal gradients may compromise experimental integrity.

Key Features

• Digitally displayed temperature and speed settings enable real-time monitoring and repeatable parameter recall.
• 0–120 minute programmable timer supports unattended operation; optional continuous mode available for extended incubation cycles.
• Stainless steel (AISI 304) inner chamber resists corrosion from aqueous buffers, saline solutions, and mild reagents—ensuring long-term structural integrity and ease of decontamination.
• Universal spring-loaded clamps accommodate diverse vessel geometries—including test tubes, flasks (up to 2 L), and multi-well plates—without requiring tool-based adjustments.
• Stepless speed control (0–300 rpm) allows fine-tuned optimization of mixing intensity, minimizing foaming and splashing while sustaining laminar fluid motion.
• Heating system employs high-efficiency tubular heating elements (1500 W) with PID-based feedback regulation, enabling rapid thermal equilibration and stable setpoint maintenance across ambient-to-50 °C range.

Sample Compatibility & Compliance

The SHY-3 accommodates standard laboratory vessels ranging from 10 mL test tubes to 2000 mL Erlenmeyer flasks on its 40 × 31 cm stainless steel platform. Its water-bath architecture inherently dampens mechanical vibration transmission, reducing risk of sample disturbance or instrument resonance. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, the device meets fundamental safety and electromagnetic compatibility requirements per GB 4793.1–2007 (equivalent to IEC 61010-1). For GLP/GMP environments, users may implement procedural controls—including calibration logs, maintenance records, and operator training documentation—to support audit readiness. The absence of exposed electronics inside the bath chamber minimizes contamination risk and simplifies cleaning validation.

Software & Data Management

The SHY-3 operates via embedded microcontroller-based hardware with no external software dependency. All operational parameters—including setpoints, elapsed time, and current temperature/speed—are displayed locally on dual LED modules. Though it lacks USB or Ethernet connectivity, its analog control interface ensures robustness in electromagnetically noisy labs and eliminates cybersecurity concerns associated with networked instruments. For laboratories requiring electronic recordkeeping, integration with external data loggers (e.g., Omega OM-DAQPRO series) is feasible via 4–20 mA or 0–5 V analog output interfaces (optional accessory). Such configurations support compliance with ALCOA+ principles when paired with validated SOPs governing calibration frequency (recommended annually), performance verification (per ASTM E2500), and deviation reporting.

Applications

• Microbial cultivation (E. coli, yeast, bacilli) under defined thermal and aeration conditions.
• Protein solubilization and ligand-binding equilibrium studies requiring constant temperature and gentle agitation.
• Biochemical assay development involving multi-step reagent addition and timed incubations.
• Environmental sample processing—including BOD testing, nutrient dissolution, and heavy metal extraction protocols.
• Pharmaceutical QC workflows such as dissolution profile analysis and excipient compatibility screening.
• Cell line maintenance in suspension culture formats prior to transfection or bioreactor inoculation.

FAQ

What safety precautions must be observed during operation?
Always ensure proper grounding of the unit before use. Never operate the shaker with an empty water bath—dry heating will permanently damage the immersion heater. Avoid introducing any liquid into the control panel housing or beneath the platform seal.
Can the SHY-3 maintain temperatures above 50 °C?
No. The maximum rated temperature is 50 °C. For higher-temperature applications (e.g., up to 100 °C), consider the WHY-2 reciprocating variant or dedicated high-temperature water baths with independent shaking modules.
Is calibration traceable to national standards?
The unit ships with factory calibration verified against NIST-traceable reference thermometers and tachometers. Users should perform in-house verification using calibrated thermistors and optical tachometers at installation and after any physical impact or extended storage.
How often does the water bath require maintenance?
Deionized water should be replaced weekly in high-use settings; biocide additives are discouraged due to potential interference with biological samples. Inspect seals and heater elements quarterly for scale accumulation or corrosion, especially in hard-water regions.
Does the shaker support multi-tier stacking or rack integration?
The SHY-3 is designed as a standalone unit with fixed footprint (69 × 46 × 48 cm). It is not engineered for vertical stacking or OEM integration into automated lab systems. Custom mounting brackets may be fabricated, but structural load limits must remain within manufacturer-specified tolerances.
