Jihepu SPH-211B-GZ Illuminated Full-Temperature Controlled Orbital Shaking Incubator

Overview

The Jihepu SPH-211B-GZ Illuminated Full-Temperature Controlled Orbital Shaking Incubator is a precision-engineered platform designed for simultaneous temperature regulation, orbital agitation, and programmable illumination—enabling reproducible cultivation of photobiological samples under tightly controlled environmental conditions. It operates on the principle of orbital shaking (circular motion with fixed amplitude), delivering uniform mixing while minimizing shear stress on sensitive biological entities such as plant callus, algal cultures, insect larvae, and aerobic microbial suspensions. Unlike water-bath shakers, this unit features an air-jacketed chamber with forced-air circulation and a high-efficiency R-134a refrigeration system, enabling stable sub-ambient cooling down to 4 °C and precise heating up to 60 °C. Its integrated illumination module provides adjustable white-light intensity (0–15,000 lx), calibrated to simulate diurnal light cycles essential for photomorphogenesis, circadian rhythm studies, and photosynthetic efficiency assays. The device complies with general laboratory safety standards for Class II equipment and supports GLP-aligned experimental workflows in academic, pharmaceutical, and agri-biotech settings.

Key Features

• Single-axis balanced drive mechanism (Chinese patent No. ZL2019XXXXXXX)—ensures mechanical stability, low vibration transmission, and acoustic noise <55 dB(A) at 1 m distance.
• PID-controlled microprocessor with environmental scanning logic—continuously monitors chamber temperature, motor load, and ambient drift to maintain setpoint accuracy within ±0.1 °C and uniformity within ±0.5 °C across the full working volume.
• Dual-line backlit LCD display—simultaneously shows real-time temperature, oscillation speed, illumination level, remaining timer duration, and active alarm status.
• CFC-free R-134a refrigeration system—meets international ozone-safety requirements (Montreal Protocol Annex A, Group I) and eliminates halogenated hydrocarbon hazards in lab environments.
• Robust structural architecture—cold-rolled steel frame reinforced with channel and angle iron; interior chamber fabricated from electropolished stainless steel (AISI 304 mirror finish) for corrosion resistance and cleanability.
• Intelligent safety protocols—including overtemperature cutoff (with independent thermal fuse), motor overheat protection, power-failure recovery, soft-start acceleration control, and audible/visual alarms for fault conditions.

Sample Compatibility & Compliance

The SPH-211B-GZ accommodates standard laboratory vessels including Erlenmeyer flasks (250–2000 mL), culture bottles, multi-well plates, and custom bioreactor sleeves. Its 890 × 480 mm platform supports configurations up to eight 2-L flasks or thirty-six 250-mL vessels—optimized for scalable suspension culture development. The chamber’s 970 × 550 × 350 mm internal volume enables vertical stacking of multiple vessel layers when used with compatible support racks. From a regulatory perspective, the instrument’s operational parameters align with common method validation frameworks referenced in ISO 13408-2 (aseptic processing), USP (cell culture systems), and ASTM D6400 (biodegradability testing under illuminated aerobic conditions). While not certified for GMP manufacturing use out-of-the-box, its data logging capability (via optional RS-485/Modbus interface) supports audit-ready documentation when integrated into validated laboratory information management systems (LIMS).

Software & Data Management

The embedded controller stores up to 10 user-defined programs with multi-segment profiles (temperature ramping, speed modulation, light/dark cycling, and timed hold steps). All runtime parameters—including actual temperature trace, RPM deviation, illumination output, and alarm events—are timestamped and retained in non-volatile memory for ≥30 days. Optional PC connectivity (via USB or RS-485) allows export of CSV-formatted logs compliant with FDA 21 CFR Part 11 requirements when paired with validated third-party software. The system supports electronic signature authentication for parameter changes and includes configurable audit trail settings (e.g., operator ID, modification time, pre-/post-change values). No proprietary cloud services or remote access are implemented—ensuring full data sovereignty and compatibility with air-gapped laboratory networks.

Applications

This incubator serves critical functions across diverse life science domains: plant tissue culture laboratories use it for light-dependent callus induction and somatic embryogenesis; microbiology units deploy it for aerobic fermentation optimization of recombinant protein expression strains; environmental labs apply it to OECD 301D-compliant ready biodegradability assays under simulated daylight; and entomology facilities rely on its stable thermal-light coupling for synchronized insect pupation studies. Additional validated applications include phytoplankton growth rate quantification (ISO 8692), seed germination kinetics per ISTA guidelines, and antibiotic susceptibility testing under photoactivated conditions (e.g., photodynamic antimicrobial therapy screening).

FAQ

Does the SPH-211B-GZ support external data logging via analog outputs?

No—this model lacks 0–10 V or 4–20 mA analog signal outputs. Data export is limited to USB/RS-485 digital interfaces.

Is the illumination spectrum tunable (e.g., red/blue ratio)?

No—the unit delivers broad-spectrum white light only (CCT ≈ 5500 K); spectral customization requires external LED arrays.

Can the shaker operate without illumination enabled?

Yes—light intensity can be set to 0 lx independently of temperature and shaking parameters.

What is the maximum allowable load imbalance on the platform?

Asymmetric loading must not exceed ±15% mass difference between opposing quadrants to maintain rotational balance and bearing longevity.

Is calibration certificate included with shipment?

A factory-issued temperature and speed verification report is provided; NIST-traceable calibration requires third-party service.
