Hanuo HNGS-30 Orbital Shaker

Overview

The Hanuo HNGS-30 Orbital Shaker is an engineered benchtop mixing instrument designed for consistent, low-shear orbital agitation of liquid samples in life science laboratories. It operates on the principle of circular orbital motion—generating uniform, non-turbulent fluid displacement ideal for cell suspension, bacterial culture maintenance, reagent homogenization, and immunoassay plate incubation. Unlike reciprocating or vortex shakers, the 30 mm orbit diameter ensures gentle yet effective mixing without excessive foaming or shear-induced cell damage—critical for sensitive biological workflows. Its brushless DC motor delivers stable rotational output across the full 50–250 rpm range, with minimal thermal drift and zero carbon brush wear, supporting long-duration unattended operation in cold rooms (4 °C) and standard lab environments (up to 45 °C). The compact footprint (284 × 264 × 90 mm) and low power consumption align with modern laboratory space and sustainability requirements.

Key Features

• Gentle 30 mm orbital motion optimized for suspension of mammalian cells, yeast cultures, and antibody-coated microplates.
• Brushless DC motor architecture ensures >20,000 hours MTBF, zero maintenance, silent operation (<45 dB(A)), and immunity to voltage fluctuations (AC 100–230 V, 50/60 Hz).
• LED digital interface displays real-time speed (rpm) and remaining timer duration; intuitive rotary knob + push-button controls reduce operator error.
• Precision timer with 1-minute minimum resolution and 99-hour 59-minute maximum range—supports delayed start, auto-shutdown, and audible end-of-cycle alert.
• Modular platform system: accepts interchangeable accessories including conical flask holders (for 50–500 mL Erlenmeyer flasks), adjustable multi-vial racks, and universal non-slip trays—configurable up to four independent platforms (optional).
• Smooth, seamless ABS+PC housing with rounded edges facilitates ISO Class 5 cleanroom-compatible wiping and disinfection; no crevices for microbial retention.

Sample Compatibility & Compliance

The HNGS-30 accommodates standard laboratory vessels—including polypropylene and glass conical flasks, PCR tube racks, deep-well plates, and serum bottles—without requiring clamps or adapters. Its 2 kg total load capacity supports simultaneous processing of multiple sample sets under identical agitation conditions, ensuring inter-batch reproducibility. While not certified for GMP manufacturing environments, the device meets IEC 61010-1:2010 safety standards for electrical equipment used in laboratory settings. Its stable speed control (±1 rpm repeatability) and timer accuracy (±0.1%) support adherence to GLP documentation requirements when integrated into validated SOPs. No internal heating or cooling elements are present; therefore, it complies with refrigerated incubator compatibility guidelines (e.g., placement inside 4 °C cold rooms per ASTM E1509).

Software & Data Management

The HNGS-30 operates as a standalone analog-digital hybrid instrument with no embedded firmware update capability or USB/Bluetooth connectivity. All operational parameters are set locally via front-panel controls and retained in non-volatile memory during power cycles. For laboratories requiring electronic recordkeeping, optional external data loggers (e.g., HOBO UX120 or Testo 176 T4) may be mounted adjacent to the unit to capture ambient temperature and runtime metadata. The device’s deterministic behavior—no software-driven variability—makes it suitable for FDA 21 CFR Part 11-compliant workflows when paired with audit-trail-enabled LIMS platforms that log user-initiated start/stop events and timer configurations.

Applications

• Maintenance of aerobic bacterial and fungal cultures in liquid media (e.g., LB, YPD) at sub-optimal shaking intensities to prevent oxygen limitation.
• Antigen-antibody binding steps in ELISA and lateral flow assay development, where uniform plate agitation improves signal-to-noise ratios.
• Cell detachment protocols using enzyme-based dissociation reagents, where controlled orbital motion enhances trypsin efficacy without mechanical stress.
• Buffer equilibration and reagent reconstitution in molecular biology workflows, particularly prior to qPCR or NGS library preparation.
• Long-term stability testing of biopharmaceutical formulations under isothermal agitation (when placed inside climate-controlled chambers).

FAQ

Is the HNGS-30 suitable for use inside a 4 °C cold room?
Yes—the operating temperature range (4–45 °C) and condensation-resistant electronics allow uninterrupted operation in refrigerated environments.
Can I run multiple flask sizes simultaneously on one platform?
Yes—interchangeable platforms include adjustable flask racks that accommodate 25 mL to 500 mL conical flasks without cross-contamination risk.
Does the shaker retain settings after power interruption?
Yes—timer and speed values are stored in non-volatile memory and restored upon power-up.
What safety certifications does this unit hold?
It conforms to IEC 61010-1:2010 for laboratory electrical safety and RoHS 2011/65/EU for hazardous substance restriction.
Is calibration required before first use?
No factory calibration is needed; however, users may verify speed accuracy using an optical tachometer per ISO 17025 traceable procedure if required by internal QA protocols.
