Overview
The Labotery YPJ-300S Dual-Deck Orbital Shaker is an industrial-grade, open-platform orbital shaker engineered for high-capacity, long-duration cell culture, fermentation, and biochemical mixing applications in bioprocessing laboratories and pilot-scale production environments. Unlike enclosed incubator shakers, this model operates without active temperature control—its design prioritizes mechanical robustness, operational continuity, and compatibility with ambient-condition workflows where external environmental control (e.g., climate-controlled rooms or external incubation chambers) is already in place. The device employs a brushless DC motor coupled with a precision-machined five-axis eccentric drive system to deliver consistent, low-vibration orbital motion across both decks. This architecture ensures minimal harmonic resonance, reduced bearing wear, and stable performance over extended duty cycles—critical for aerobic microbial cultivation, suspension cell expansion, and reagent homogenization requiring reproducible shear profiles.
Key Features
- Brushless DC motor drive with closed-loop speed regulation: delivers ±1 rpm frequency accuracy across the full 30–300 rpm range and eliminates carbon brush maintenance over >20,000 operating hours.
- Dual independent decks (800 × 600 mm each), configurable for simultaneous multi-vessel processing—supports scalable loading from 250 mL flasks (up to 84 total) to 2 L vessels (up to 24 total).
- Microprocessor-based controller with large backlit LCD display: enables intuitive setting and real-time monitoring of speed, timer, and system status; supports forward/reverse rotation sequencing for specialized mixing protocols.
- Extended timer function (0–9999 minutes), programmable in minute or hour increments; retains user settings after power interruption via non-volatile memory.
- Integrated safety architecture: includes over-temperature audiovisual alarm (triggered at >35°C internal cabinet temperature), automatic power cutoff, and self-diagnostic routines for motor current, encoder feedback, and thermal sensor integrity.
- Structural frame fabricated from reinforced cold-rolled steel with vibration-dampening rubber mounts; meets ISO 14644-1 Class 8 cleanroom-compatible handling standards when used with appropriate lab containment practices.
Sample Compatibility & Compliance
The YPJ-300S accommodates standard Erlenmeyer flasks (100–2000 mL), baffled bottles, carboys, and custom bioreactor vessels mounted on universal clamps or silicone matting. Its open-deck configuration allows unrestricted access for sampling, gas exchange, and integration with external sensors (e.g., dissolved oxygen probes, pH electrodes). While not certified as a medical device or GMP-grade unit, the shaker complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) electromagnetic compatibility standards. Its mechanical design aligns with ASTM E1249-17 guidelines for orbital shaker performance verification, and operational logs—including speed setpoint, runtime, and fault codes—can be exported manually for GLP documentation per laboratory SOP requirements.
Software & Data Management
The YPJ-300S operates via embedded firmware with no proprietary PC software dependency. All parameters are configured and monitored locally through the front-panel interface. For traceability, users may manually record operational logs (start time, target rpm, duration, deck load configuration) into laboratory notebooks or LIMS-integrated spreadsheets. Optional RS-485 serial output (available upon request) enables connection to building management systems or centralized SCADA platforms for remote status polling—though no native data logging or FDA 21 CFR Part 11-compliant electronic signature functionality is provided. Audit trails must be maintained externally per institutional quality policy.
Applications
- Aerobic bacterial and yeast fermentation in shake-flask bioprocess development
- Mammalian and insect cell suspension culture under controlled ambient conditions
- Enzyme reaction kinetics studies requiring uniform mixing without thermal interference
- Media preparation, buffer equilibration, and reagent dissolution for downstream purification
- Environmental microbiology sample agitation prior to plating or nucleic acid extraction
- Quality control testing of raw materials in pharmaceutical excipient manufacturing (non-sterile stages)
FAQ
Is the YPJ-300S suitable for use inside a CO₂ incubator?
No—the unit is not designed for sealed, humidified, or elevated-CO₂ environments; its electronics and motor cooling rely on ambient airflow.
Can the two decks operate at different speeds simultaneously?
No—both decks are mechanically synchronized and share a single speed setpoint.
What is the maximum flask fill volume recommended for 300 rpm operation?
For optimal mixing efficiency and splash control, fill volume should not exceed 20% of nominal flask capacity at ≥250 rpm.
Does the shaker support validation protocols such as IQ/OQ?
Yes—mechanical performance verification (e.g., rpm accuracy, orbit consistency, timer deviation) can be performed using third-party calibrated tachometers and stopwatch measurements per internal lab validation SOPs.
Is service support available outside mainland China?
Technical documentation and spare parts (motor assemblies, control boards, deck brackets) are distributed globally through authorized Labotery partners; field service requires advance coordination with regional distributors.
