Overview

The ShiPing DJS-2013 Series is an engineered vertical stackable incubatory shaker designed for high-throughput, temperature-sensitive biological and biochemical applications requiring precise control of both thermal and mechanical parameters. Utilizing a patented single-axis balanced drive mechanism, this dual-shelf system delivers stable orbital or reciprocating motion across a wide frequency range (50–300 rpm) with exceptional repeatability (±1 rpm accuracy). Its full-temperature capability—spanning 4°C to 60°C—is achieved via a CFC-free R-134a refrigeration system coupled with high-efficiency resistive heating, enabling uninterrupted operation in cold-room environments or elevated incubation protocols. The unit’s forced-air convection circulation ensures uniform temperature distribution (±0.25°C) throughout the stainless-steel mirror-finish chamber (550 × 480 × 550 mm), accommodating large-volume vessels—including four 5 L Erlenmeyer flasks—without compromising thermal or kinetic stability. Designed for integration into regulated laboratory workflows, its microprocessor-based PID controller supports GLP-compliant parameter logging and meets foundational requirements for audit-ready operation under ISO/IEC 17025 and USP analytical instrument qualification frameworks.

Key Features

• Patented single-axis balanced drive system eliminates mechanical backlash and reduces operational noise to <55 dB(A), ensuring long-term reliability and minimal vibration transmission to adjacent equipment.
• Dual independent shelves (456 × 450 mm each) support flexible configuration: top shelf for low-heat-load cultures; bottom shelf for high-power applications or auxiliary modules (e.g., humidity sensor, UV germicidal lamp).
• Front-access door with tempered glass viewport and integrated LED illumination enables real-time visual monitoring without interrupting temperature or oscillation profiles.
• Eight-stage programmable controller allows sequential ramping of speed, temperature, and time—ideal for gradient-based solubilization, protein expression induction, or multi-phase hybridization protocols.
• Comprehensive safety architecture includes independent over-temperature cutoff (mechanical backup thermostat), over-speed shutdown, door-open interlock, ground-fault circuit interruption (GFCI), and motor thermal protection—each isolated to prevent cascading failure.
• AC variable-frequency induction motor (60 W) provides constant torque across the full speed range, zero carbon-brush wear, and maintenance-free operation exceeding 20,000 hours MTBF.
• Power-loss recovery function automatically resumes the last active program upon grid restoration, preserving experimental continuity and data integrity.

Sample Compatibility & Compliance

The DJS-2013 Series accommodates standard microbiological and molecular biology vessels—from 2 mL microcentrifuge tubes to 5 L baffled flasks—on adjustable aluminum bottle racks or universal platform inserts. Its chamber geometry and airflow design comply with ASTM E1510-22 guidelines for shaker performance verification. Temperature and speed calibration points are traceable to NIST-certified references (certificate available upon request). The unit conforms to IEC 61010-1:2010 for electrical safety in laboratory environments and incorporates electromagnetic compatibility (EMC) shielding per EN 61326-1. Optional firmware upgrades enable 21 CFR Part 11 compliance through electronic signature capture, audit trail generation, and role-based user access control—supporting GMP/QbD workflows in biopharmaceutical development labs.

Software & Data Management

Equipped with an embedded PID microcontroller and dual-line LCD display, the shaker presents real-time values for setpoint/actual temperature, speed, elapsed time, and remaining timer. All operational parameters—including eight-program memory, calibration offsets, and alarm thresholds—are stored in non-volatile EEPROM. An RS-485 communication port (Modbus RTU protocol) enables integration into centralized lab management systems (LIMS) or SCADA networks. Optional PC software (ShiPing LabControl v3.2) provides remote monitoring, CSV export of time-stamped temperature/speed logs, and automated report generation compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Microbial culture expansion and fermentation optimization under controlled thermal-oxygenation conditions.
• Plasmid DNA purification and protein expression in E. coli, Pichia, or mammalian suspension cells.
• Antibody-antigen binding assays, ELISA plate washing, and Western blot membrane agitation.
• Solubility screening, liquid–liquid extraction, and dye penetration kinetics in material science studies.
• Hybridization buffer equilibration for Northern/Southern blotting and FISH protocols.
• Clinical diagnostic sample homogenization and reagent mixing prior to PCR or immunoassay analysis.

FAQ

What is the maximum flask size supported per shelf?
Each shelf accommodates up to four 5 L baffled flasks (total 8 × 5 L in stacked configuration), provided vessel height does not exceed 450 mm.
Is the refrigeration system suitable for continuous 4°C operation?
Yes—the CFC-free R-134a system with 200 W cooling capacity maintains stable sub-ambient temperatures even at full load and ambient conditions up to 30°C.
Can the shaker be validated for GMP use?
The base unit meets IQ/OQ prerequisites per ASTM E2500; PQ validation kits—including thermocouple mapping templates and speed verification fixtures—are available from authorized service partners.
Does the device support external humidity control?
Humidity sensing is optional; active humidification requires third-party integration via 0–10 V analog output and dedicated chamber modification.
What is the warranty coverage and service support structure?
Standard 24-month parts-and-labor warranty; global technical support via certified regional service centers with 72-hour on-site response for critical failures.
