Overview
The ShiPing DJS-2012 Stackable High-Capacity Temperature-Controlled Orbital/Reciprocal Shaker is engineered for demanding life science and bioprocessing applications requiring precise, reproducible agitation under tightly regulated thermal conditions. Utilizing a patented single-shaft balanced drive mechanism, the system delivers stable orbital or reciprocating motion across a broad frequency range (50–300 rpm) with exceptional mechanical consistency—critical for cell culture expansion, microbial suspension homogenization, hybridization kinetics, and solvent-based extraction protocols. Its thermally insulated chamber integrates a CFC-free R134a refrigeration system and high-efficiency heating elements (800 W), enabling continuous operation from 4°C to 60°C with ±0.1°C setpoint accuracy and ±0.5°C intra-chamber uniformity—validated per ISO 17025 traceable calibration practices. Designed for modular lab infrastructure, three units can be vertically stacked without compromising footprint or airflow integrity, maintaining full accessibility and thermal stability across all tiers.
Key Features
- PID-controlled microprocessor with dual-line LCD display showing real-time temperature, speed, elapsed time, and programmed segment status
- Eight-segment programmable protocol engine supporting ramped temperature/speed profiles, repeat cycles, and timed hold steps
- Electropolished 316L stainless-steel interior chamber—corrosion-resistant, non-porous, and compliant with USP and ISO 10993-5 for biocompatibility
- Soft-start acceleration circuitry prevents sample splashing and ensures gentle initiation of oscillation—essential for fragile cultures and low-viscosity reagents
- Independent dual-safety architecture: dedicated over-temperature cutoff (mechanical backup thermostat + electronic sensor), over-speed detection, door-interlock shutdown, and Class I leakage current protection per IEC 61010-1
- High-load capacity platform (850 × 560 mm) accommodating up to twelve 2 L Erlenmeyer flasks or forty 250 mL bottles—optimized for scalable upstream processing
- Energy-efficient brushless AC induction motor (120 W) with constant torque output across full speed range; zero maintenance, no carbon brushes, >20,000 hr service life
Sample Compatibility & Compliance
The DJS-2012 supports diverse vessel types—including glass and PETG flasks, centrifuge tubes, deep-well plates, and custom bioreactor bags—without vibration-induced resonance artifacts. Its forced-air convection system ensures uniform thermal distribution regardless of load configuration, meeting ASTM E2500-13 requirements for equipment qualification in GxP environments. The unit complies with FDA 21 CFR Part 11-ready data logging when integrated with optional audit-trail-enabled software (sold separately). Stainless-steel construction satisfies GLP/GMP cleaning validation standards (e.g., residue testing per USP ), while the absence of fluorinated refrigerants aligns with EU F-Gas Regulation (EU No 517/2014) and EPA SNAP program guidelines.
Software & Data Management
While the embedded controller provides local parameter storage and power-failure recovery, the DJS-2012 is compatible with ShiPing’s optional LabLink™ PC interface (RS-485/USB) for remote monitoring, real-time graphing, and CSV export of temperature/speed/time logs. Audit-trail functionality—enabling user authentication, event timestamping, and immutable record retention—is available through validated firmware upgrade (v3.2+). All data files conform to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and support 21 CFR Part 11 compliance when deployed with electronic signature modules.
Applications
- Mammalian and insect cell culture in serum-free or suspension media, including CHO, HEK293, and Sf9 lines
- Bacterial and yeast fermentation optimization (E. coli, P. pastoris) under controlled dissolved oxygen proxies
- Nucleic acid hybridization (Southern/Northern blotting), antigen-antibody binding assays, and ELISA plate washing
- Solvent extraction of natural products, polymer dissolution studies, and buffer equilibration protocols
- Clinical microbiology specimen homogenization (blood cultures, sputum digestion) per CLSI M22-A3 standards
- Environmental sample preparation for EPA Method 1664B (oil & grease) and ISO 11885 (metal leaching)
FAQ
Does the DJS-2012 support both orbital and reciprocating motion modes?
Yes—the unit features switchable oscillation geometry via front-panel selection, allowing users to optimize mixing efficiency for viscous vs. low-density samples without hardware modification.
Can it operate unattended for extended durations?
With its 500-hour timer, power-failure auto-resume function, and redundant thermal safeguards, the DJS-2012 is qualified for overnight and multi-day incubation runs in ISO 13485-certified labs.
Is the refrigerated version (DJS-2012R) validated for sub-ambient operation?
Yes—the R variant achieves stable 4°C setpoints even at ambient temperatures up to 35°C, verified using NIST-traceable PT100 probes per IQ/OQ protocols.
What maintenance intervals are recommended?
No routine lubrication is required. Annual verification of temperature uniformity, speed calibration, and safety interlocks is advised per manufacturer’s PQ documentation.
Are third-party accessories (e.g., CO₂ sensors, humidity modules) supported?
ShiPing offers OEM-integrated options including UV germicidal lamps, analog 4–20 mA environmental probes, and gas-permeable inlet manifolds—all pre-calibrated and mechanically anchored to the chassis.
