CZGY SY-88B High-Capacity Water-Bath Incubator Shaker

Overview

The CZGY SY-88B High-Capacity Water-Bath Incubator Shaker integrates precise temperature regulation with uniform orbital agitation in a single robust platform. Engineered for reproducible thermal and mechanical stimulation of biological samples, it operates on the principle of water-mediated conductive heating combined with controlled reciprocating motion—ensuring minimal thermal gradient deviation (<±0.3 °C across bath volume) and consistent shear delivery across large-volume vessels. Unlike air-jacketed shakers, its submerged bath design delivers superior temperature homogeneity and dampens mechanical vibration transmission to sensitive cultures. The unit is optimized for applications requiring simultaneous incubation and mixing at elevated temperatures—particularly where glycerol stocks, bacterial expression cultures, enzyme kinetics assays, or hybridization reactions demand both thermal stability and mechanical agitation over extended durations (up to 9999 minutes per cycle).

Key Features

• Brushless DC motor drive system ensures maintenance-free operation, constant rotational speed under variable load conditions, and low electromagnetic interference—critical for long-duration cell culture or protein expression protocols.
• Electropolished 304 stainless steel water bath tank resists corrosion from saline buffers, acidic media, and repeated sterilization cycles; integrated drain valve enables rapid fluid exchange and cleaning.
• Dual independent timing circuits allow concurrent programming of temperature hold duration and oscillation activation—enabling staggered start/stop sequences (e.g., pre-warm phase without shaking, followed by agitation onset).
• PID-based digital temperature controller with segmented LCD display provides real-time monitoring of bath temperature and setpoint; auto-tuning algorithm adapts to ambient fluctuations and load changes.
• Orbital motion with 30 mm amplitude generates laminar, non-turbulent flow profiles suitable for suspension cultures, biofilm development studies, and gentle reagent mixing—avoiding foam formation or cell shearing observed in high-amplitude vortex shakers.
• Large-format platform (850 × 500 mm) accommodates multiple standard flasks (up to 5 L each), deep-well microplates, or custom trays—supporting scalable process development from benchtop to pilot-scale bioprocessing workflows.

Sample Compatibility & Compliance

The SY-88B supports glass, polypropylene, and polycarbonate vessels—including Erlenmeyer flasks (100 mL to 5 L), baffled flasks, multi-well plates, and custom bioreactor sleeves—without compromising thermal transfer efficiency. Its temperature range (ambient to 100 °C) complies with common sterilization protocols (e.g., 80 °C for 30 min depyrogenation of glassware) and enables thermophilic microbial cultivation (e.g., Geobacillus stearothermophilus). The instrument meets IEC 61010-1 safety standards for laboratory equipment and incorporates grounded chassis construction, overtemperature cutoff (105 °C fail-safe limit), and current-limiting circuitry. While not certified for GMP manufacturing environments, its traceable temperature control, stable PID performance, and audit-ready timer logs align with GLP documentation requirements for academic and industrial R&D laboratories.

Software & Data Management

The SY-88B operates via embedded firmware with no external PC dependency. All operational parameters—including setpoints, elapsed time, actual temperature, and real-time RPM—are displayed simultaneously on the dual-line segment LCD. Timer logs are retained through power interruption (non-volatile memory). For integration into regulated environments, optional RS-485 Modbus RTU interface (available upon request) permits remote parameter readout and basic command control via LabVIEW, Python, or SCADA systems. Though lacking native 21 CFR Part 11 compliance features (e.g., electronic signatures), the device supports manual logbook correlation through timestamped operator entries and printed timer records—sufficient for ISO/IEC 17025-accredited testing labs conducting method validation under SOP-controlled conditions.

Applications

• Bacterial and yeast fermentation studies requiring sustained oxygen transfer at 30–37 °C
• Thermal denaturation and refolding assays of recombinant proteins (4–60 °C)
• Antibiotic susceptibility testing with broth microdilution under agitation
• Hybridization kinetics in Southern/Northern blotting workflows (42–65 °C)
• Preparation of homogeneous cell lysates for proteomics sample prep
• Accelerated stability testing of biopharmaceutical formulations (25–40 °C, ICH Q1A)
• Enzymatic digestion optimization for chromatin immunoprecipitation (ChIP)

FAQ

What is the maximum recommended liquid volume per vessel on the SY-88B platform?
For optimal heat transfer and orbital consistency, fill volume should not exceed 70% of vessel capacity—e.g., ≤3.5 L in a 5 L flask. Total bath loading should remain below 80 L to maintain thermal response time within specification.
Can the SY-88B operate continuously for 72 hours or longer?
Yes—the brushless motor and reinforced bearing assembly are rated for uninterrupted operation up to 168 hours; however, periodic visual inspection of bath water level and temperature calibration verification is recommended every 24 hours in extended runs.
Is the stainless steel bath compatible with 70% ethanol or 10% bleach solutions for decontamination?
Electropolished 304 SS withstands short-term exposure (<15 min) to these agents; prolonged immersion may cause surface dulling. Rinse thoroughly with DI water afterward to prevent chloride-induced pitting.
Does the unit support ramp-and-soak temperature profiles?
No—the controller implements only static setpoint regulation; programmable ramps require external PID controllers or third-party automation modules.
What is the typical warm-up time from ambient to 60 °C with a full 60 L water load?
Approximately 42–48 minutes, depending on ambient humidity and initial water temperature; heating rate decreases logarithmically as setpoint approaches due to reduced ΔT driving force.
