Overview
The CZGY HY-8A High-Capacity Constant-Speed Orbital Shaker is an engineered solution for laboratories requiring robust, reproducible mixing of large-volume samples under non-temperature-controlled conditions. Designed around a precision orbital motion principle—where the platform rotates in a horizontal circular path with a fixed 20 mm diameter—the instrument delivers uniform agitation without vortexing or splashing, making it especially suitable for cell suspension, microbial culture propagation, reagent homogenization, and sample preparation prior to analytical workflows such as ELISA, PCR setup, or chromatographic injection. Its microprocessor-controlled drive system incorporates real-time power compensation to maintain constant rotational speed across variable load conditions (up to 40 kg), minimizing drift even during extended operation (up to 8 hours continuous). Unlike variable-speed shakers reliant on analog potentiometers, the HY-8A employs digital setpoint control with ±1 rpm repeatability—a critical attribute for method transfer between labs and long-term protocol consistency in GLP-compliant environments.
Key Features
- High-capacity platform (700 × 620 mm) accommodates multiple flasks, bottles, or trays simultaneously—ideal for high-throughput microbiology labs and environmental testing facilities.
- Digital speed control (60–300 rpm) with LED display and intuitive UP/DN keypad interface; adjustable in 1-rpm increments for precise method alignment.
- Extended timer range (0–9999 minutes) supports unattended overnight incubation protocols and multi-stage shaking sequences.
- Dual operating modes: Auto mode (predefined speed/time) and Manual mode (0–99% output voltage control), enabling fine-tuned optimization for viscous or shear-sensitive samples.
- Reinforced steel frame and vibration-dampening feet ensure mechanical stability at higher speeds; optional floor-mounting via M10 threaded inserts recommended for sustained operation ≥240 rpm.
- Overload protection circuitry and grounded 3-pin power input comply with IEC 61010-1 safety standards for laboratory electrical equipment.
Sample Compatibility & Compliance
The HY-8A accepts standard laboratory vessels including Erlenmeyer flasks (up to 5 L), centrifuge bottles, petri dish stacks, and custom rack-mounted tubes—secured via optional mesh clamps or universal rubber grips. Its open-platform design facilitates rapid cleaning and sterilization (autoclavable accessories available separately). While not certified for ISO/IEC 17025 calibration traceability out-of-box, the instrument’s digital speed readout and stable torque delivery support internal verification against NIST-traceable tachometers. It meets basic requirements for ASTM D2240 (rubber hardness testing sample prep), USP (non-sterile compounding agitation), and ISO 8573-1 (compressed air system sampling)—provided users validate performance per their SOPs. No integrated temperature regulation means it is excluded from applications requiring thermal control per ISO 15190 or CLSI EP25-A.
Software & Data Management
The HY-8A operates as a standalone hardware unit with no embedded software stack or network connectivity. All parameter inputs (speed, time, mode) are stored in non-volatile memory and retained after power cycling. For audit readiness in regulated settings, users may document operational parameters manually or integrate the shaker into external LIMS via RS-232 (optional add-on module) or analog 0–10 V output (for speed monitoring). The device does not implement FDA 21 CFR Part 11 electronic signature or audit trail functionality; however, its deterministic behavior—no firmware updates, no user-modifiable algorithms—simplifies validation under GMP Annex 11 and EU GMP Chapter 4 frameworks when used as a fixed-parameter ancillary device.
Applications
- Microbial culture expansion in aerobic bioreactors and shake-flask screening systems.
- Homogenization of soil/water extracts for heavy metal analysis (EPA Method 3050B).
- Antibiotic susceptibility testing media preparation (CLSI M07-A10).
- Immunoassay plate washing buffer equilibration and antigen-antibody binding enhancement.
- Pre-analytical processing of clinical specimens (e.g., whole blood mixing prior to serum separation).
- Quality control of industrial fermentation broths and food-grade enzyme solutions.
FAQ
Does the HY-8A support temperature-controlled operation?
No. The HY-8A is a non-thermostatic orbital shaker. For combined temperature and agitation, consider CZGY’s HY-8A-compatible water bath or air-jacketed incubator shaker variants.
What is the maximum safe operating speed with full 40 kg load?
Rated speed stability is guaranteed up to 280 rpm at 40 kg. Above this, mechanical resonance may occur; floor anchoring is strongly advised.
Can the timer be paused and resumed?
No—the timer is non-interruptible. Once started, it runs to completion unless manually stopped via RUN/STOP key.
Is calibration documentation provided with shipment?
Factory calibration certificate (speed verification at 100/200/300 rpm) is available upon request at no additional cost.
Are replacement mesh clamps and platform liners available?
Yes. Standard stainless-steel mesh clamps (PN: HY-CLAMP-M20) and silicone-coated platform liners (PN: HY-LINER-700) are stocked and ship within 3 business days.
