Overview
The EYELA MMV-1000W is a precision-engineered separatory funnel shaker designed for reproducible, controlled liquid–liquid extraction in analytical, pharmaceutical, and environmental laboratories. Unlike conventional orbital or reciprocating shakers, the MMV-1000W employs a dual-mode oscillation mechanism—vertically linear or tilt-axis rocking—enabling users to select the optimal mixing profile based on phase density differential, interfacial tension, and emulsion stability requirements. Its motion follows a defined sinusoidal displacement path with a fixed 40 mm amplitude, ensuring consistent mechanical energy input per cycle. The tilt-angle adjustment (0–20°) allows fine-tuning of shear stress distribution across the liquid interface, facilitating efficient mass transfer while minimizing foam formation or phase inversion—critical for trace-level analyte recovery in EPA Method 1664, ASTM D95, or USP residual solvent workflows.
Key Features
- Dual oscillation modes: Selectable vertical linear motion (20–300 cycles/min) or tilt-axis rocking (20–250 cycles/min) via front-panel toggle switch.
- Angle-adjustable tilt mechanism: Precision-machined pivot assembly enables smooth, repeatable 0–20° inclination setting without tools.
- Digital cycle counter with non-volatile memory: Displays real-time oscillation count and retains last operating parameters (speed, mode, duration) after power-off.
- Brushless DC motor drive: Delivers stable speed control across full range, minimal thermal drift, and >20,000-hour service life under continuous operation.
- Soft-start/soft-stop profile: Programmable ramp-up (0–3 s) and ramp-down (0–3 s) reduces mechanical shock to glassware, extending separatory funnel longevity and preventing stopper ejection.
- Acoustically optimized housing: Sound-dampened chassis and vibration-isolated motor mount limit operational noise to ≤55 dB(A) at 1 m distance—compliant with ISO 7779 and OSHA 29 CFR 1910.95 workplace noise guidelines.
- Ergonomic clamp system: Quick-release lever mechanism secures flasks from 50 mL to 3000 mL without tools; standard and large clamp sets included.
Sample Compatibility & Compliance
The MMV-1000W accommodates standard ground-glass jointed separatory funnels (ISO 22241, DIN 12500) ranging from 50 mL to 3000 mL volume capacity. Clamp geometry maintains uniform center-of-gravity alignment during tilt oscillation, preventing torque-induced slippage or seal failure. All wetted components are chemically resistant to common extraction solvents (e.g., dichloromethane, ethyl acetate, hexane, methanol/water mixtures). The unit meets IEC 61010-1:2010 safety standards for laboratory equipment and carries PSE certification for Japanese market compliance. For regulated environments, its timer function supports GLP-compliant documentation when paired with external audit-trail-capable lab notebooks or LIMS interfaces.
Software & Data Management
The MMV-1000W operates as a standalone instrument with no embedded firmware or network connectivity. However, its digital display output (cycle count, speed, elapsed time) is compatible with analog-to-digital signal loggers (e.g., National Instruments USB-6009) for automated data capture. Users may integrate it into validated workflows requiring 21 CFR Part 11 compliance by recording operational parameters—including date/time stamp, operator ID, funnel size, solvent pair, and total cycles—in electronic batch records. No proprietary software is required; configuration remains fully manual and deterministic, eliminating cybersecurity risks associated with connected devices.
Applications
- Pharmaceutical QC: Residual solvent extraction per ICH Q3C guidelines using headspace-GC validation protocols.
- Environmental testing: Oil and grease analysis (EPA 1664B), pesticide residue isolation (AOAC 2007.01), and PFAS pre-concentration from aqueous matrices.
- Food safety: Mycotoxin (aflatoxin B1, ochratoxin A) extraction from cereals and nuts prior to LC-MS/MS quantification.
- Academic research: Kinetic studies of liquid–liquid partition coefficients (log P) under controlled agitation intensity.
- Clinical toxicology: Urine drug screening sample preparation involving back-extraction of basic drugs into organic phase.
FAQ
Can the MMV-1000W be used with non-standard or custom-shaped glassware?
No—it is engineered exclusively for conical-bottom, ground-glass-jointed separatory funnels conforming to ISO 22241 dimensional tolerances. Use of non-standard vessels may compromise sealing integrity and introduce safety hazards.
Is calibration required before first use or at scheduled intervals?
The device contains no user-serviceable sensors or transducers; speed accuracy is maintained by the brushless DC motor’s internal encoder and is factory-verified per JIS B 7021. No routine calibration is specified, though periodic verification using a handheld tachometer (e.g., Extech 461923) is recommended for GLP audits.
Does the unit support external triggering or remote start/stop via TTL or RS-232?
No—the MMV-1000W has no external control ports. All operation is initiated and modified manually via the front-panel keypad and rotary encoder.
What maintenance is required to ensure long-term performance?
Monthly inspection of clamp jaw integrity and pivot lubrication (with silicone-based grease); annual verification of motor mounting bolt torque (2.5 N·m) and vibration isolation pad compression.
