Overview
The JingHong ZDP Series Constant-Temperature Shaking Incubator is an engineered platform for controlled microbial growth, cell culture propagation, and biochemical reaction kinetics under simultaneous temperature regulation and orbital agitation. Designed around a dual-layered, configurable shaking chamber, the system operates on the principle of horizontal orbital motion—generating uniform, low-shear fluid mixing ideal for aerobic suspension cultures in Erlenmeyer flasks, test tubes, and bioreactor vessels. Its microprocessor-controlled PID temperature system maintains setpoints within ±0.1 °C stability and ±0.5 °C uniformity across the working chamber, while the adjustable 28 mm orbit diameter ensures reproducible mass transfer without foaming or cell damage. The ZDP and HZP variants differ primarily in minimum operating temperature (RT+5 °C vs. 5 °C), enabling extended low-temperature applications such as psychrophilic strain cultivation or cold-adapted enzyme assays.
Key Features
- Dual-tier, modular shelf architecture: Independent upper and lower platforms can be reconfigured into a single large-height layer to accommodate tall vessels—including 1000 mL flasks—without compromising structural rigidity or thermal homogeneity.
- Precision orbital drive mechanism: Brushless DC motor with surge-resistant coupling delivers consistent 30–280 rpm speed control (±1 rpm resolution) and long-term mechanical reliability under continuous load.
- Intelligent thermal management: Triple-point calibrated PT100 sensor array, insulated double-wall chamber, and optimized air circulation ducts minimize vertical and horizontal temperature gradients.
- Programmable operation: Up to 99-hour timer with auto-restart function; independent setting of temperature and shaking parameters with password-protected configuration lock.
- Safety-certified construction: Over-temperature cutoff, motor overload protection, and door-open alarm comply with IEC 61010-1 safety standards for laboratory equipment.
Sample Compatibility & Compliance
The ZDP series accommodates standard laboratory glassware including 100 mL to 1000 mL Erlenmeyer flasks, culture tubes, and multi-well plates (with optional adapters). Standard configurations support up to 44 × 250 mL flasks per run—optimized for high-throughput screening workflows in academic microbiology labs and QC departments. All models meet GB/T 23792–2009 (Chinese national standard for incubators) and are compatible with ISO/IEC 17025-compliant validation protocols. While not FDA 21 CFR Part 11–certified out-of-the-box, audit-ready operation logs (via optional RS-232/USB data export) support GLP/GMP documentation requirements when integrated into validated laboratory information management systems (LIMS).
Software & Data Management
Onboard LCD interface provides real-time display of setpoint, actual temperature, shaking speed, elapsed time, and error codes. Optional PC connectivity (via RS-232 or USB-to-serial adapter) enables remote parameter adjustment and time-stamped data logging using JingHong’s proprietary LabControl Suite v3.2. Export formats include CSV and Excel-compatible .xls, facilitating integration with statistical process control (SPC) tools and electronic lab notebooks (ELNs). Firmware supports firmware version tracking and user-defined calibration offsets—critical for maintaining traceability during instrument qualification (IQ/OQ/PQ).
Applications
- Microbial culture expansion (E. coli, Bacillus spp., yeast) under aerobic conditions
- Recombinant protein expression in shake-flask bioprocess development
- Environmental isolate enrichment at defined temperatures (e.g., 25 °C for soil bacteria, 37 °C for clinical isolates)
- Solubility and dissolution rate studies of pharmaceutical excipients
- Enzyme kinetic assays requiring controlled thermal and mixing environments
- Seed train preparation prior to bioreactor inoculation
FAQ
Can the dual-layer shelves be used independently?
Yes—the upper and lower platforms operate on separate support rails and may be removed or repositioned to create a single large-height chamber (up to 300 mm clearance) for oversized vessels.
Is external humidity control available?
No—this model is designed for non-humidified operation. For moisture-sensitive applications, users should pair with desiccant packs or operate inside a secondary humidity-controlled environment.
What is the recommended calibration frequency?
Per ISO/IEC 17025 guidance, temperature sensors should be verified quarterly using NIST-traceable reference thermometers; shaking speed calibration is advised semiannually with optical tachometry.
Does the unit support ramp-and-soak temperature profiles?
No—this is a single-setpoint incubator. Multi-step thermal programming requires external PLC integration via analog output signals (optional add-on module).
Are CE or UL certifications available?
The ZDP series carries CCC certification for domestic Chinese markets. CE marking is not applicable; UL listing is available upon request for OEM distribution channels under private-label agreements.
