Shanghai Shiping DJS-D2016R Stackable Incubated Orbital Shaker

Overview

The Shanghai Shiping DJS-D2016R Stackable Incubated Orbital Shaker is an engineered solution for high-throughput, temperature-controlled cell culture, microbial growth, and biochemical incubation applications requiring precise orbital agitation. Designed around a robust single-axis balanced drive architecture, it delivers stable, low-vibration motion across its full speed range (0–300 rpm) while maintaining tight thermal control (4–60 °C) via integrated air-cooled R134a refrigeration and high-efficiency heating. Its 265 L chamber—lined entirely with electropolished 304 stainless steel featuring seamless, radius-rounded internal corners—ensures corrosion resistance, ease of decontamination, and compliance with GLP laboratory hygiene standards. The unit supports up to three vertically stacked configurations without footprint expansion, enabling scalable capacity within constrained lab spaces—a critical advantage in biopharma QC labs and academic core facilities where floor area optimization is essential.

Key Features

• Stackable modular design: Up to three DJS-D2016R units can be physically stacked using reinforced structural frames and interlocking alignment guides—each retaining independent operation, full parameter control, and individual safety monitoring.
• Single-axis balanced drive system: Eliminates mechanical resonance and reduces operational noise to <55 dB(A) at 1 m, ensuring compatibility with sensitive imaging setups and quiet laboratory environments.
• PID-controlled thermal management: Dual-stage regulation with independent refrigeration (334 W R134a compressor) and heating (1200 W resistive elements) achieves ±0.1 °C setpoint stability and ≤±1 °C uniformity at 37 °C across the entire chamber volume.
• Full-parameter LCD interface: Backlit dual-line display shows real-time temperature, speed, timer, and programmed segment status; all parameters support password-protected locking to prevent unauthorized modification.
• Comprehensive safety architecture: Includes redundant over-temperature cutoffs (electromechanical + electronic), motor overheat detection, refrigerant pressure monitoring, ground-fault circuit interruption (GFCI), and automatic power-loss recovery with non-volatile memory retention.
• Ergonomic access design: Lower two tiers feature downward-swinging doors with gas-assisted dampers; top tier uses upward-lifting hinged access—paired with fully retractable, low-friction drawer-style platform trays for unobstructed vessel loading.

Sample Compatibility & Compliance

The DJS-D2016R accommodates diverse vessel formats on its 920 × 540 mm aluminum-alloy platform, including Erlenmeyer flasks (up to 2000 mL × 15), culture bottles, deep-well plates, and custom bioreactor sleeves. Bottle clamps are fabricated from mirror-finish stainless steel with calibrated elastic modulus (360° torsional resilience) and Vickers hardness ≥420 HV, preventing deformation under prolonged cyclic loading. Chamber materials comply with ISO 8573-1 (compressed air purity) for optional UV sterilization integration and meet ASTM F2101 requirements for surface bioburden reduction when equipped with the optional 254 nm UV-C lamp module. All electrical subsystems conform to IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use), and firmware supports audit-trail logging compatible with FDA 21 CFR Part 11 Annex 11 workflows when paired with validated networked data capture systems.

Software & Data Management

While the DJS-D2016R operates autonomously via its embedded PID controller, it supports RS-485 Modbus RTU communication for integration into centralized lab automation platforms (e.g., LabVantage, STARLIMS). The controller stores up to 10 user-defined multi-step programs—including ramp/soak profiles with up to eight segments—and retains all runtime logs (temperature, speed, elapsed time, alarms) in non-volatile memory for ≥12 months. Optional Ethernet-to-Modbus gateways enable remote monitoring, parameter adjustment, and event-triggered email/SMS alerts. All calibration offsets (temperature, speed) are traceable to NIST-traceable references, and the system supports periodic verification per ISO/IEC 17025:2017 clause 7.8.2 for measurement uncertainty assessment.

Applications

This shaker serves as a primary platform for aerobic microbial cultivation (E. coli, Pseudomonas, Bacillus spp.), suspension mammalian cell expansion (CHO, HEK293), yeast fermentation kinetics, enzyme activity assays under controlled thermal conditions, and long-term stability studies compliant with ICH Q1A(R3). Its wide temperature span (4–60 °C) enables cold-adapted psychrophile propagation and thermophile screening, while the orbital motion profile (Φ50 mm) ensures optimal oxygen transfer in non-baffled vessels—validated per USP and EP 2.6.27 for compounding microbiology workflows. In bioprocess development, it functions as a scalable bridge between shake-flask screening and benchtop bioreactors, particularly for media optimization and inoculum preparation.

FAQ

What is the maximum recommended load per platform, and how is load distribution verified?
The platform supports up to 60 × 250 mL flasks (total mass ≤35 kg) when evenly distributed. Load balance is empirically verified per ISO 13370 Annex B using vibration spectral analysis at 100/200/300 rpm.
Does the unit support validation documentation (IQ/OQ/PQ) packages?
Yes—Shanghai Shiping provides GMP-compliant IQ/OQ templates aligned with ASTM E2500-13 and EU GMP Annex 15, including sensor calibration certificates, door seal integrity test protocols, and thermal mapping procedures for stacked configurations.
Can the shaker operate continuously for >72 hours without intervention?
Yes—the system is rated for continuous duty (IEC 60034-1 duty cycle S1) with active thermal derating logic that modulates compressor duty cycle above 45 °C to ensure 10,000-hour MTBF for critical components.
Is the refrigeration system serviceable in situ, and what refrigerant is used?
The R134a-based sealed-system compressor is field-serviceable using standard HVAC tools; refrigerant charge (185 g ±5 g) is labeled per ASHRAE Standard 15 and complies with EU F-Gas Regulation No. 517/2014.
How is condensation managed during low-temperature operation?
An integrated anti-condensation heater maintains cabinet wall temperature >2 K above dew point; no frost accumulation occurs below 10 °C, verified per IEC 60068-2-51 cold-humidity cycling tests.
