Overview
The Hanuo HNLZ-10 Vertical & Tilt Oscillating Separatory Funnel Shaker is an engineered laboratory instrument designed for reproducible, controlled liquid–liquid extraction and phase mixing in analytical and preparative workflows. It operates on a dual-mode mechanical oscillation principle—employing either vertical reciprocating motion or adjustable-angle tilt oscillation—to generate consistent shear forces across heterogeneous sample systems. Unlike orbital shakers or vortex mixers, the HNLZ-10 delivers linear, repeatable displacement with fixed amplitude (40 mm), enabling precise control over interfacial contact time, emulsification intensity, and mass transfer kinetics—critical parameters in EPA Method 3510C, ASTM D3764, and ISO 11348-based extraction protocols. Its brushless DC motor ensures long-term frequency stability under variable load conditions, while the low-noise (<55 dB[A]) operation supports integration into shared analytical laboratories without acoustic interference.
Key Features
- Dual oscillation configuration: switch between vertical and tilt modes (0–22° continuously adjustable) to optimize mixing efficiency for high-viscosity or density-mismatched phases.
- Digital frequency display with memory function: retains last-used oscillation count upon power-off; supports both timed (0–999 min) and continuous operation modes.
- Stepless speed control: fine-tuned adjustment from 10 to 300 cycles/min (vertical) or 20 to 250 cycles/min (tilt), facilitating method development across diverse solvent systems (e.g., dichloromethane/water, hexane/acetone, ethyl acetate/buffer).
- Soft-start and soft-stop ramping: minimizes mechanical shock to glassware, reducing risk of stopper ejection, seal failure, or funnel fracture during initiation or termination.
- High-load platform: accommodates two parallel loads up to 13 kg each—including full 1000 mL separatory funnels with clamps—ensuring scalability for multi-sample batch processing.
- Ergonomic fixture system: quick-release universal clamps compatible with standard ground-glass jointed funnels (150–1000 mL) and stoppered cylindrical bottles; no tools required for installation or removal.
Sample Compatibility & Compliance
The HNLZ-10 is validated for use with borosilicate glass separatory funnels conforming to ASTM E288–22 dimensional tolerances and ISO 385 volumetric accuracy standards. Its mechanical design eliminates rotational torque that may compromise PTFE stopcock integrity or cause misalignment in precision-ground joints. The unit complies with IEC 61010-1:2010 safety requirements for laboratory electrical equipment, including protection against electric shock, mechanical hazards, and abnormal temperature rise. While not certified for Class I Division 1 hazardous locations, it meets CE marking directives for EMC (2014/30/EU) and Low Voltage (2014/35/EU). Routine operation aligns with GLP documentation practices when paired with external audit-trail-capable timers or LIMS-integrated scheduling software.
Software & Data Management
The HNLZ-10 operates as a standalone hardware platform with embedded microcontroller logic—no proprietary software or driver installation required. All operational parameters (mode, frequency, timer value, elapsed cycles) are displayed on a backlit LED interface and retained in non-volatile memory. For traceability in regulated environments (e.g., environmental testing labs accredited to ISO/IEC 17025), users may log settings manually or integrate the shaker into broader lab automation via RS-232 or optional TTL-triggered I/O modules (sold separately). Data export is compatible with CSV-formatted spreadsheets for inclusion in analytical reports, SOP appendices, or internal QA review packages.
Applications
- Environmental analysis: solid-phase and liquid–liquid extraction of priority pollutants (PAHs, PCBs, organochlorine pesticides) from soil, sediment, and aqueous matrices per EPA SW-846 Methods 3510B, 3520C, and 3540C.
- Food safety testing: fat-soluble vitamin recovery, mycotoxin extraction from cereals, and pesticide residue isolation prior to GC-MS or LC-MS/MS quantification.
- Pharmaceutical R&D: partition coefficient (log P) determination, API solubility screening, and formulation stability assessment using biphasic buffer–organic systems.
- Clinical toxicology: forensic drug extraction from biological fluids (urine, plasma) employing chloroform–isopropanol or MTBE–water partitions.
- Academic research: kinetic studies of phase-transfer catalysis, surfactant-mediated micelle formation, and polymer dissolution behavior in mixed solvent systems.
FAQ
Is the HNLZ-10 suitable for use with volatile organic solvents such as diethyl ether or chloroform?
Yes—the shaker’s fully enclosed base housing and non-sparking brushless DC motor meet general laboratory safety guidelines for handling Class I flammable liquids; however, use in ventilated fume hoods is strongly recommended.
Can the tilt angle be calibrated or locked at discrete positions?
The tilt mechanism features a continuously adjustable stainless-steel hinge with vernier scale markings (0°, 5°, 10°, 15°, 20°, 22°); final positioning is secured via knurled locking thumbscrew.
Does the unit support external trigger input for synchronization with autosamplers or data acquisition systems?
Standard configuration includes passive dry-contact terminals for start/stop signaling; optional RS-232 communication module enables bidirectional command execution and real-time status polling.
What maintenance is required to ensure long-term frequency accuracy?
No routine calibration is needed—the motor controller maintains ±1% frequency tolerance across its full range; periodic inspection of clamp jaw integrity and platform leveling is advised every 6 months.
Are replacement fixtures available for non-standard vessel geometries (e.g., conical centrifuge tubes or custom extraction cartridges)?
Hanuo offers OEM-compatible accessory kits including universal spring-loaded clamps, silicone-coated cradles, and modular bracket adapters—contact technical support for dimensional specifications and ordering codes.
