Zhichu ZHTY-70 Benchtop Incubated Orbital Shaker

Overview

The Zhichu ZHTY-70 is a benchtop incubated orbital shaker engineered for precise, reproducible cultivation of microbial, mammalian, and suspension cell cultures under controlled temperature and agitation conditions. Utilizing orbital motion with a fixed 26 mm diameter orbit, the system delivers uniform mixing and optimal oxygen transfer across culture vessels—critical for aerobic growth kinetics and metabolic consistency. Unlike generic platform shakers, the ZHTY-70 integrates P.I.D. microcomputer temperature control, forced-air convection, and a triple-tier stainless steel shelf architecture to maintain thermal homogeneity (±1°C at 37°C) throughout the chamber volume. Designed for GLP-compliant laboratories, it operates within a stable temperature envelope from ambient +5°C to 60°C—making it suitable for mesophilic fermentation, enzyme expression studies, and routine microbiological assays without refrigeration capability (note: ZQTY-70 variant includes compressor-based cooling; ZHTY-70 is heating-only). Its 518 × 424 mm aluminum-alloy shaker platform supports scalable vessel configurations—including up to 30 × 250 mL flasks or 6 × 2 L bioreactors—enabling seamless transition from screening to pilot-scale cultivation.

Key Features

• Triple-shelf design with independent load distribution—optimized for mechanical stability during high-frequency operation (up to 400 rpm) and long-duration runs
• P.I.D. intelligent temperature control with ±0.1°C setpoint accuracy and real-time digital LCD display (backlit, password-locked interface)
• Three-dimensional eccentric cam drive mechanism—ensures low-vibration, wear-resistant oscillation with <55 dB(A) acoustic emission
• Forced convection system with silent axial fans and strategically positioned air inlets—guarantees rapid thermal equilibration and minimal vertical gradient
• Power-fail recovery function with non-volatile memory retention—automatically resumes pre-interruption settings post-outage
• Over-temperature cutoff and fault-triggered auto-shutdown—complies with IEC 61010-1 safety requirements for laboratory equipment
• Front-access tempered glass door with anti-fog coating—enables continuous visual monitoring without thermal disturbance
• Electrostatically coated steel housing and mirror-finish 304 stainless steel interior—resistant to corrosion from ethanol, acids, and repeated decontamination cycles

Sample Compatibility & Compliance

The ZHTY-70 accommodates standard laboratory vessels via interchangeable universal plastic clamps (included) or optional stainless steel fixtures—supporting Erlenmeyer flasks (250–2000 mL), test tubes, deep-well plates, and custom bioreactor sleeves. Its 320 mm clearance between top shelf and chamber ceiling allows upright placement of tall culture vessels. The unit meets electromagnetic compatibility standards per CISPR 11 Group 1, Class B, and incorporates ferrite magnetic rings to suppress conducted interference—ensuring signal integrity when integrated with adjacent analytical instruments (e.g., pH meters, dissolved oxygen probes). While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, its deterministic timer (0.1-hour resolution), auditable parameter logs (via optional RS-232/USB export), and hardware interlocks support traceable operation under internal QA protocols aligned with ISO 9001 and CLSI M22-A3 guidelines.

Software & Data Management

The ZHTY-70 operates as a standalone instrument with embedded firmware—no proprietary software required for basic operation. All parameters (temperature setpoint, rpm, timer duration, ramp profiles) are stored in EEPROM with battery-backed retention. Optional data logging modules enable timestamped CSV export of real-time temperature and speed values at user-defined intervals (1–60 min), facilitating post-run correlation with growth curves or metabolic activity assays. For labs requiring electronic records compliance, third-party SCADA platforms (e.g., LabVIEW, Ignition) can integrate via Modbus RTU over RS-485—supporting audit trails, user-level access control, and alarm event tagging per ALCOA+ principles.

Applications

• Microbial propagation for antibiotic susceptibility testing (AST) and bioburden analysis per USP & EP methods
• Suspension cell culture maintenance in CHO, HEK293, and insect cell lines under standardized agitation regimes
• Enzyme production optimization in recombinant E. coli and Bacillus strains
• Media preparation and solubilization of heat-sensitive reagents requiring gentle warming + mixing
• Environmental microbiology—soil extract enrichment, waterborne pathogen amplification, and biofilm dispersion assays
• Teaching laboratories: kinetic modeling of exponential growth phases using OD₆₀₀ time-series data

FAQ

Does the ZHTY-70 support refrigeration?
No—the ZHTY-70 is a heating-only incubated shaker with temperature control from ambient +5°C to 60°C. For sub-ambient operation, consider the ZQTY-70 variant equipped with a hermetic compressor and eco-friendly R134a refrigerant.
What is the maximum load capacity per shelf?
Each 518 × 424 mm shelf supports up to 15 kg uniformly distributed. Total system payload across three shelves must not exceed 45 kg to maintain mechanical resonance stability at 400 rpm.
Is UV sterilization available on the ZHTY-70?
UV germicidal irradiation is standard on the ZQTY-70 model only. The ZHTY-70 does not include integrated UV lamps; however, external UV-C cabinets may be used for pre-chamber sterilization.
Can the timer be programmed for intermittent shaking cycles?
The built-in timer supports single-segment countdown only (0–999.9 h). Multi-step cycling requires external programmable relays or PLC integration via the dry-contact output port.
Are calibration certificates provided with shipment?
Factory calibration reports (temperature uniformity, speed accuracy ±1 rpm) are included. NIST-traceable certification and on-site IQ/OQ validation services are available upon request through authorized Zhichu service partners.
