JIHEPU SPH-1102 Vertical Dual-Door Double-Layer Incubated Orbital Shaker

Overview

The JIHEPU SPH-1102 is a vertically configured, dual-door, double-layer incubated orbital shaker engineered for high-throughput, temperature-controlled cell culture, microbial growth, enzymatic assays, and biochemical reaction kinetics. It operates on the principle of orbital agitation—where platform motion follows a circular trajectory at a defined diameter (25 mm)—ensuring uniform suspension of aerobic cultures while minimizing shear stress on sensitive biological samples. Unlike reciprocating or rocking platforms, orbital motion provides consistent mixing across flask volumes without vortexing or splashing, making it ideal for E. coli expression, yeast fermentation, mammalian suspension cultures, and hybridization protocols requiring stable thermal and mechanical environments. The unit maintains precise temperature control from ambient +5°C up to 60°C via a PID-regulated resistive heating system integrated into an insulated air-jacketed chamber. Its vertical architecture optimizes laboratory floor space while accommodating two independently accessible, load-balanced shaking platforms—each supporting standardized culture vessels ranging from 50 mL test tubes to 1000 mL baffled flasks.

Key Features

• Patented single-axis balanced drive mechanism—reducing mechanical vibration transmission, energy consumption, and acoustic noise (<55 dB(A) at 1 m)
• Dual independent access doors with tempered glass viewing windows—enabling non-intrusive monitoring and sequential sample loading without disturbing adjacent shelves
• Microprocessor-based PID controller with environmental scanning logic—continuously adjusting heater output based on ambient drift, load mass, and door-opening events
• Backlit dual-line LCD display—simultaneously showing setpoint and real-time values for temperature, speed, and remaining time
• Memory retention function—preserving user-defined parameters (temp, rpm, duration) after power interruption
• Soft-start acceleration profile—ramping speed gradually over 15 seconds to prevent liquid spillage and protect fragile cell aggregates
• Brushless AC induction motor—rated for >50,000 hours MTBF, delivering constant torque across the full 40–300 rpm range without carbon brush wear or commutator maintenance
• Over-temperature safety cutoff with redundant thermal sensors—triggering audible/visual alarms and cutting heater power if chamber temperature exceeds setpoint by >3°C

Sample Compatibility & Compliance

The SPH-1102 accommodates standard laboratory vessels including Erlenmeyer flasks (50–1000 mL), culture tubes, multi-well plates (with optional adapter trays), and serum bottles. Its 734 × 464 mm shelves support configurations such as 24 × 1000 mL flasks (at 25% fill level), 44 × 500 mL flasks, or 56 × 250 mL flasks—optimized for scalable bioprocess development. Chamber construction complies with IEC 61010-1:2010 for electrical safety in laboratory equipment. Stainless steel interior surfaces meet ISO 14644-1 Class 7 cleanroom compatibility requirements when operated under controlled HVAC conditions. While not certified for GMP manufacturing, the device supports GLP-compliant workflows through its parameter logging capability, audit-ready timer functionality, and traceable thermal performance (±0.1°C accuracy, ±1°C uniformity per ASTM E2203–22). Optional RS-485 interface enables integration into centralized lab monitoring systems compliant with FDA 21 CFR Part 11 when paired with validated data acquisition software.

Software & Data Management

The SPH-1102 operates autonomously via embedded firmware with no external PC dependency. All operational parameters—including temperature setpoint, oscillation frequency, timer duration, and elapsed runtime—are stored in non-volatile memory. The controller logs up to 100 event timestamps (e.g., door openings, alarm triggers, power resumption) with date/time stamps for basic traceability. For advanced data capture, optional USB-to-RS485 converter modules allow connection to third-party SCADA or LIMS platforms supporting Modbus RTU protocol. Exported CSV files include timestamped temperature and speed readings at 10-second intervals—sufficient for QC documentation in academic, pharmaceutical preclinical, and contract research settings. Firmware updates are performed via secure UART bootloader, with version history retained in system diagnostics.

Applications

• Bacterial and fungal cultivation (e.g., E. coli, S. cerevisiae) under controlled aeration and temperature
• Protein expression studies requiring precise OD₆₀₀ tracking during exponential-phase growth
• Enzyme kinetic assays where substrate solubility and mixing homogeneity affect V_max and K_m determination
• Molecular hybridization (Southern/Northern blotting) with stringent wash temperature control
• Biopharmaceutical upstream process development—scaling from shake flasks to benchtop bioreactors
• Environmental microbiology—BOD testing, nutrient broth enrichment, and antibiotic susceptibility screening
• Food safety labs—pathogen enrichment (e.g., Salmonella, Listeria) per ISO 6579 and AOAC guidelines

FAQ

Is the SPH-1102 suitable for applications requiring refrigeration?
No—the SPH-1102 is a heating-only air-jacketed incubator shaker. For sub-ambient operation, consider the SPH-2102 variant equipped with R134a refrigeration.
Can both shelves operate at different temperatures or speeds?
No—both shelves share a common thermal chamber and drive system; they maintain identical temperature and oscillation parameters simultaneously.
What is the maximum flask fill volume recommended at 300 rpm?
For 1000 mL flasks, do not exceed 250 mL (25% fill ratio) to prevent foaming, splashing, or uneven oxygen transfer at high agitation rates.
Does the unit comply with electromagnetic compatibility (EMC) standards?
Yes—it meets EN 61326-1:2013 for laboratory equipment emission and immunity profiles.
Is calibration documentation provided with shipment?
A factory calibration certificate (traceable to NIST standards) is included, covering temperature sensor accuracy and rotational speed verification at three points (100/200/300 rpm).
