Overview
The ShiPing DJS-2019R Plus Stackable Incubator Shaker is an engineered solution for simultaneous temperature-controlled incubation and orbital or reciprocating agitation of biological samples in microbiology, molecular biology, fermentation, and cell culture applications. It operates on the principle of controlled convection-based thermal regulation combined with mechanically stabilized oscillation—ensuring uniform heat distribution and consistent mixing dynamics across the entire chamber volume. Unlike conventional shakers with limited thermal precision or single-function incubators, this unit integrates P.I.D.-driven microprocessor control with real-time environmental scanning to maintain temperature stability within ±0.2 °C and speed accuracy within ±1 rpm. Its stackable architecture supports up to three identical units vertically aligned—optimizing floor space without compromising airflow integrity or mechanical isolation—making it suitable for high-density lab environments where footprint efficiency and experimental reproducibility are critical.
Key Features
- Stackable modular design: Up to three DJS-2019R Plus units can be securely stacked using reinforced structural interfaces, eliminating the need for separate benchtop or floor-standing installations while preserving independent operational control per unit.
- Dual-mode oscillation: Switchable between orbital (circular) and reciprocating (linear back-and-forth) motion via intuitive touchscreen interface—enabling optimization for suspension cultures (e.g., E. coli, yeast), mammalian cell lines, or viscous media requiring directional shear.
- 7-inch full-color TFT capacitive touch display: Graphical UI with multilingual support (English default), real-time parameter visualization, programmable curve editing, and encrypted access levels to prevent unauthorized configuration changes.
- Single-axis balanced drive system: Precision-machined 45# carbon steel shaft (220–250 HBW hardness, quenched & tempered), coupled with NSK double-row angular contact bearings, delivers ultra-low vibration (<0.5 mm/s RMS) and acoustic noise <52 dB(A) at 1 m distance—critical for sensitive long-term assays.
- Robust safety architecture: Dual independent over-temperature cut-offs (electronic + mechanical), refrigeration compressor overload monitoring, ground-fault circuit interruption (GFCI), and auto-recovery logic following mains interruption—all compliant with IEC 61010-1 safety standards for laboratory equipment.
- Corrosion-resistant chamber: Seamless 304 stainless steel interior with electropolished mirror finish and radius-rounded corners facilitates complete sterilization (autoclavable accessories compatible) and prevents microbial retention in crevices.
Sample Compatibility & Compliance
The DJS-2019R Plus accommodates standard laboratory vessels—including Erlenmeyer flasks (up to 2000 mL), test tubes, deep-well plates, and custom bioreactor bags—via its 420 × 400 mm stainless steel platform fitted with adjustable spring-loaded clamps (360° elastic range, 420 HV hardness). Chamber geometry ensures laminar airflow distribution across all load configurations, validated per ISO 14644-1 Class 5 cleanroom airflow principles. The system meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and electrical safety (EN 61010-1). When operated with validated firmware and audit-trail-enabled data logging software, it supports compliance with GLP, GMP, and FDA 21 CFR Part 11 for regulated biopharmaceutical process development and QC testing.
Software & Data Management
Embedded firmware supports eight-segment programmable ramp-hold profiles, including multi-step temperature-speed coupling (e.g., ramp to 37 °C while accelerating from 100 → 250 rpm over 30 min). All operational parameters—including setpoints, actual values, alarms, and timestamps—are logged internally with non-volatile memory retention (>100,000 entries). Optional Ethernet or RS-485 connectivity enables integration into centralized LIMS or SCADA platforms. Data export is available in CSV format with ISO 8601 timestamping. Parameter encryption, user role management (admin/operator/guest), and factory-reset confirmation protocols ensure procedural integrity during method transfer and cross-lab validation.
Applications
- Microbial growth kinetics studies under controlled thermal and agitation conditions (ASTM D5210 for biodegradation assays)
- Recombinant protein expression in shake-flask bioreactors (E. coli, Pichia pastoris)
- Cell line expansion and passaging for monoclonal antibody production
- Enzyme activity profiling across temperature gradients with concurrent mixing
- Environmental microbiology: BOD incubation, soil respiration assays, and water quality bioassays
- Pharmaceutical stability testing per ICH Q1A(R2) guidelines requiring precise temperature cycling and agitation
FAQ
Can the DJS-2019R Plus operate continuously for 72+ hours without manual intervention?
Yes—the unit supports uninterrupted operation up to 999.59 hours with built-in power-fail recovery, ensuring protocol continuity even during grid instability.
Is remote monitoring supported out-of-the-box?
Remote status viewing and basic parameter adjustment require optional communication modules (Ethernet/WiFi add-on kit); local touchscreen remains fully functional without network dependency.
What maintenance is required for the refrigeration system?
The sealed R134a system is maintenance-free under normal operation; annual verification of condenser coil cleanliness and refrigerant pressure is recommended per ISO/IEC 17025 preventive maintenance schedules.
Does the unit comply with USP & EP requirements for microbiological incubation?
While not certified to USP or Ph. Eur. 2.6.27 by default, its temperature uniformity (±1 °C at 37 °C) and stability (≤±0.2 °C) meet the technical thresholds specified in those chapters when qualified per IQ/OQ/PQ protocols.
Can multiple users share one unit with individual access rights?
Yes—administrator-defined user accounts with tiered permissions (view-only, parameter edit, full configuration) are enforced via password-protected login and session timeout.
