Overview
The Hanuo HNGS-20 Orbital Shaker is an engineered platform for gentle, uniform mixing of liquid samples in life science laboratories. It operates on the principle of orbital motion—where the platform rotates in a circular path at a defined diameter (20 mm nominal)—generating consistent, low-shear agitation ideal for cell culture maintenance, microbial suspension, ELISA plate incubation, and reagent homogenization. Unlike reciprocating or vortex shakers, orbital motion minimizes foaming and cellular shear stress while ensuring high reproducibility across replicates. Designed for continuous operation in standard lab environments—including cold rooms (4 °C) and ambient-controlled workspaces—the unit features a robust aluminum-alloy chassis, sealed electronics, and thermally stable motor housing to sustain performance under variable environmental loads.
Key Features
- Brushless DC motor drive: Ensures >20,000-hour service life, zero carbon brush wear, and silent operation (<45 dB[A] at 1 m distance), eliminating routine maintenance and reducing long-term TCO.
- Four independent orbital platforms: Configurable with interchangeable mounting surfaces—compatible with universal flat trays, adjustable conical flask holders (for 50–1000 mL vessels), and microplate racks—enabling parallel processing of heterogeneous sample formats.
- Precision digital control: LED interface displays real-time speed (rpm) and remaining timer duration; intuitive rotary encoder allows fine-tuned adjustment without menu navigation.
- Extended timing capability: Programmable timer spans 1 minute to 99 hours 59 minutes with auto-shutdown and audible alert—validated for unattended overnight protocols compliant with GLP documentation workflows.
- Cold-room rated design: Certified operational stability from 4 °C to 45 °C; non-condensing enclosure seals protect internal circuitry during refrigerated incubation applications.
- Ergonomic and cleanable form factor: Streamlined polycarbonate housing with smooth, non-porous surfaces facilitates ISO 5-compliant wipe-downs; footprint measures only 284 × 264 × 90 mm for benchtop space optimization.
Sample Compatibility & Compliance
The HNGS-20 supports a broad range of vessel types including Erlenmeyer flasks (50–500 mL), test tubes (13–25 mm OD), deep-well microplates (96-/384-well), and custom bioreactor sleeves. Its 20 mm orbit diameter delivers optimal mixing efficiency for viscous media up to 15 cP without splashing or vortex formation. The system meets electromagnetic compatibility (EMC) requirements per EN 61000-6-3 (emission) and EN 61000-6-2 (immunity), and conforms to low-voltage directive 2014/35/EU. While not intrinsically safe for explosive atmospheres, it is routinely deployed in ISO Class 7 cleanrooms and FDA-regulated QC labs where mechanical reliability and audit-ready operation are prerequisites.
Software & Data Management
This standalone shaker operates without proprietary software—designed for plug-and-play integration into existing LIMS or electronic lab notebook (ELN) ecosystems. All operational parameters (start time, duration, setpoint rpm) are manually entered and retained in non-volatile memory across power cycles. For GxP environments, users may log settings via external timestamped entries; optional RS-232 or USB-to-serial adapters (sold separately) enable basic parameter logging compatible with CSV export for 21 CFR Part 11–aligned audit trails when paired with validated third-party acquisition software.
Applications
- Maintenance of suspension mammalian cell cultures (e.g., CHO, HEK293) in serum-free media
- Pre-analytical sample homogenization prior to flow cytometry, PCR, or mass spectrometry workflows
- Antibody-antigen binding kinetics studies requiring constant low-shear agitation
- Microbial growth curve analysis under controlled temperature–agitation coupling (when used inside environmental chambers)
- Buffer equilibration and reagent reconstitution in molecular biology core facilities
- Quality control testing of diagnostic kits requiring standardized mixing protocols per ISO 13485 Annex C
FAQ
Is the HNGS-20 suitable for use inside a 4 °C cold room?
Yes. Its operating temperature range is certified from 4 °C to 45 °C, and all electronics are conformally coated to resist condensation-related failure.
Can I run multiple flask sizes simultaneously on one platform?
Yes—using the optional adjustable conical flask holder, users can secure vessels ranging from 50 mL to 1000 mL on a single platform without cross-contamination risk.
Does the unit support protocol recall or multi-step programs?
No. It is a single-parameter, single-stage device optimized for simplicity and reliability—not programmable sequence execution.
What safety certifications does the HNGS-20 carry?
CE marking per Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and RoHS 2011/65/EU compliance documentation is provided with each unit.
How is load imbalance handled during operation?
The brushless motor and precision-machined bearing assembly automatically compensate for minor imbalances (≤10% mass asymmetry); however, symmetrical loading across the platform is recommended for maximum longevity and noise suppression.
