CZGY GYYP-2F Dual-Layer Floor-Standing Orbital Shaker

Overview

The CZGY GYYP-2F Dual-Layer Floor-Standing Orbital Shaker is an open-frame, high-capacity orbital shaker engineered for scalable biological and biochemical processing in ambient-temperature environments. It operates on the principle of horizontal circular motion (orbital shaking) with a fixed 26 mm orbit diameter, generating uniform shear and mixing profiles ideal for aerobic microbial cultivation, cell suspension maintenance, enzyme reaction kinetics, and reagent homogenization. Unlike incubator shakers, the GYYP-2F is specifically designed for integration into controlled ambient rooms or walk-in chambers where temperature stability is externally maintained—making it a cost-optimized solution for high-throughput fermentation labs, bioprocess development facilities, and QC microbiology units requiring simultaneous handling of large-volume cultures.

Key Features

• Dual-tier platform architecture: Two independently accessible, load-balanced stainless-steel shelves (each accommodating up to 15 × 5000 mL Erlenmeyer flasks), enabling parallel processing of up to 30 vessels per run without cross-platform interference.
• High-torque servo motor drive (450 W rated output): Delivers stable rotational performance across the full 30–300 rpm range with ±1 rpm speed accuracy, validated under continuous 24/7 operation at maximum load.
• Dual-loop digital control system: Combines real-time speed feedback (velocity loop) with dynamic current regulation (current loop) to maintain consistent orbital motion under variable load conditions—critical for reproducible aeration and mixing efficiency.
• Intuitive LCD interface: Supports dual-unit timer programming (minutes or hours), real-time rpm display, and power-on default retention; no external PC required for basic operation.
• Robust mechanical construction: Heavy-duty steel frame (1570 × 830 × 1270 mm overall dimensions), reinforced shelf supports, and vibration-dampened feet ensure operational stability even at upper-speed ranges with asymmetric flask loading.

Sample Compatibility & Compliance

The GYYP-2F accommodates standard laboratory glassware—including 50 mL to 5000 mL Erlenmeyer flasks, Fernbach flasks, and custom bioreactor vessels—via interchangeable clamp kits (standard configuration includes 5000 mL universal clamps). Its ambient-only design complies with ISO 13485 manufacturing practices for non-sterile lab equipment and meets CE safety directives (EN 61000-6-2/6-3, EN 61010-1) for electrical laboratory instruments. While not certified for GLP/GMP-controlled environments out-of-the-box, its deterministic timer logic, non-volatile parameter memory, and absence of cloud connectivity support internal audit readiness when deployed within validated facility infrastructures.

Software & Data Management

The GYYP-2F operates as a standalone instrument with no embedded data logging or network interface. All operational parameters—including setpoint speed, elapsed time, and remaining timer—are retained in non-volatile memory during power interruption. For laboratories requiring electronic recordkeeping, third-party USB data loggers or PLC-integrated SCADA systems may be interfaced via analog 0–10 V speed output (optional accessory port). The device does not implement FDA 21 CFR Part 11-compliant user authentication or audit trail functionality; such capabilities must be provided at the facility level through LIMS or MES integration.

Applications

• Large-scale microbial propagation for seed train expansion in biomanufacturing.
• Aerobic culture of E. coli, Bacillus, Pichia pastoris, and other oxygen-dependent strains in non-sterile benchtop or room-scale workflows.
• Buffer and media preparation with uniform dissolution and degassing prior to filtration or sterilization.
• Long-duration stability studies of liquid formulations under ambient storage conditions (e.g., excipient solubility monitoring).
• Supporting ASTM D5527 “Standard Practice for Laboratory Shaking of Aqueous Samples” protocols where temperature control is externally managed.

FAQ

Is the GYYP-2F suitable for use inside an incubator or environmental chamber?
No—it lacks integrated heating or cooling elements and is rated only for ambient-temperature operation. It must be placed in a pre-conditioned space where temperature and humidity are externally regulated.
Can I install custom flask clamps or adapt the platform for non-standard vessels?
Yes. The unit accepts OEM-designed clamp kits compatible with M6 threaded mounting holes spaced at 100 mm intervals across both shelves.
Does the timer support countdown-to-stop or repeat-cycle modes?
It provides a single-cycle countdown timer only (0–9999 min/h); repeat or interval functions require external programmable relay control.
What is the maximum permissible load imbalance per shelf?
For optimal mechanical longevity and speed stability, asymmetry should not exceed 15% of total shelf load (e.g., ≤2.25 kg deviation on a 15 kg nominal load).
Is service documentation available in English?
Yes—electronic copies of the English-language operation manual, wiring diagrams, and spare parts list are supplied with each unit and available upon request from CZGY Technical Support.
