Overview
The CZGY SHY-2A Dual-Mode Water Bath Orbital & Reciprocal Shaker is an integrated benchtop bioprocess instrument engineered for precise temperature-controlled agitation of liquid and semi-solid samples in life science, microbiology, and biochemical laboratories. It combines a thermostatically regulated water bath chamber with a dual-motion oscillation platform—capable of both orbital (circular) and reciprocal (linear back-and-forth) motion—enabling flexible optimization of mixing dynamics for diverse sample types. The system operates on the principle of convective heat transfer within a stainless-steel water jacket and mechanical energy transfer via a balanced eccentric drive mechanism, ensuring uniform thermal distribution (±0.5 °C) and stable speed control across the full 0–300 rpm range. Designed for reproducible incubation and suspension culture, it supports standard protocols in microbial growth, enzyme kinetics, solubility studies, and cell-based assays where simultaneous thermal stability and controlled mechanical stimulation are critical.
Key Features
- Dual-mode operation: Selectable orbital or reciprocal motion via front-panel toggle—optimized for suspension homogeneity (orbital) or particle resuspension/precipitation studies (reciprocal).
- Digital PID temperature control with real-time LED display (range: ambient +5 °C to 100 °C; stability: ≤±0.5 °C; uniformity: ≤±0.5 °C).
- Stepless speed regulation from 0 to 300 rpm with soft-start motor control to minimize mechanical shock during acceleration.
- Stainless-steel water bath chamber (304 grade) with corrosion-resistant interior and sealed heating element (1500 W power rating).
- Universal spring-loaded clamping system accommodates tubes (φ16×300 mm), Erlenmeyer flasks (100 mL×24, 200 mL×15, 250 mL×12), and custom vessels without adapter kits.
- Programmable timer (0–120 minutes) with audible end-of-cycle alert and auto-shutdown functionality.
- Robust cast-aluminum chassis with non-slip rubber feet; compact footprint (700×550×490 mm) suitable for standard laboratory benches.
Sample Compatibility & Compliance
The SHY-2A accommodates aqueous, buffered, and low-viscosity organic solutions up to 250 mL per vessel. Its open-bath configuration allows direct immersion of containers into temperature-equilibrated water—ideal for heat-sensitive biological samples requiring gentle, uniform thermal input. The unit complies with general electrical safety requirements per IEC 61010-1 (2010) for laboratory equipment. While not certified for GLP/GMP environments out-of-the-box, its digital logging-capable architecture (via optional RS232 interface) supports traceable parameter recording aligned with internal SOPs. For applications governed by USP , ISO 8573, or ASTM D1193, users must validate temperature uniformity and speed accuracy per their site-specific qualification protocol.
Software & Data Management
The SHY-2A operates as a standalone analog-digital hybrid controller with no embedded firmware or network connectivity. All operational parameters—including setpoint temperature, target rpm, and timer duration—are configured locally via tactile membrane keys and displayed on dual 4-digit LED screens. No proprietary software is required. However, when interfaced with external data loggers (e.g., Omega OM-DAQPRO or Testo 176 T4), time-stamped temperature and speed values can be exported for audit-ready documentation. For labs operating under FDA 21 CFR Part 11 requirements, manual entry of setpoints into electronic lab notebooks (ELNs) with user authentication fulfills basic traceability needs.
Applications
- Microbial culture expansion in nutrient broths and selective media (e.g., E. coli LB, yeast YPD).
- Enzyme activity assays requiring constant temperature and homogeneous substrate mixing.
- Solubility and dissolution testing of pharmaceutical excipients and APIs in aqueous buffers.
- Antibiotic susceptibility testing (AST) using broth microdilution methods per CLSI M07-A11.
- Cell detachment and re-suspension in adherent mammalian culture workflows prior to passaging.
- Extraction efficiency studies for plant metabolites, soil analytes, or environmental contaminants.
- Calibration verification of thermometers and RTDs using stirred water baths per ASTM E74.
FAQ
What is the maximum load capacity per flask position?
The platform supports up to 24 × 100 mL Erlenmeyer flasks or equivalent total mass (~8 kg) when evenly distributed.
Can the water bath operate without oscillation?
Yes—the shaker motor can be disabled while maintaining independent temperature control for static incubation.
Is deionized water required for the bath?
Distilled or deionized water is strongly recommended to prevent mineral scaling and extend heater lifespan.
Does the unit include overtemperature or dry-run protection?
It features a redundant bimetallic thermal cutoff switch but lacks automated dry-run detection; users must monitor water level manually.
What maintenance is required for long-term reliability?
Monthly cleaning of the bath chamber with mild detergent, annual inspection of the O-ring seal, and biannual verification of temperature sensor calibration.
