DRETOP F10-3000 Separatory Funnel Shaker

Overview

The DRETOP F10-3000 Separatory Funnel Shaker is an engineered laboratory shaker specifically designed for high-throughput liquid–liquid extraction workflows in environmental, food safety, agricultural, and regulatory testing laboratories. It operates on a reciprocating oscillation principle—mechanically driven by a robust stepless-speed motor coupled with a balanced dual-arm linkage system—to generate consistent, low-shear, repeatable motion across multiple large-volume separatory funnels simultaneously. Unlike orbital or rotary shakers, this device delivers controlled linear displacement along a vertical or precisely angled plane, ensuring uniform phase mixing while minimizing emulsion formation and funnel cap leakage. Its low center-of-gravity structural design guarantees mechanical stability during extended operation at maximum amplitude and frequency, eliminating resonance-induced drift or vibration transmission to adjacent instrumentation.

Key Features

• Single-platform configuration supporting up to ten 3000 mL separatory funnels—optimized for batch-scale extraction without manual intervention
• Stepless frequency control (0–300 cycles/min) with programmable soft-start and soft-stop algorithms to prevent sudden torque loading and sample splashing
• Dual oscillation modes: selectable vertical reciprocation or adjustable-angle tilting (0–20°), enabling method-specific optimization for density-mismatched systems
• ≥40 mm oscillation amplitude—engineered to ensure complete phase interfacial contact in high-viscosity or surfactant-laden matrices
• LCD digital interface with independent timer (0–9999 minutes), real-time frequency display, and non-volatile parameter memory
• Tool-free, vertically sliding sample clamp mechanism—allows rapid loading/unloading of funnels ranging from 125 mL to 3000 mL without repositioning or hardware adjustment
• Stainless steel-reinforced frame and corrosion-resistant powder-coated housing—designed for long-term reliability in solvent-rich lab environments

Sample Compatibility & Compliance

The F10-3000 accommodates standard borosilicate glass and PTFE-stoppered separatory funnels (125–3000 mL), including ASTM D3417-compliant configurations for polymer solubility testing and EPA Method 3510C-compatible setups for halogenated hydrocarbon extraction. Its mechanical design conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for laboratory equipment. While the unit operates at ambient temperature only, its stable motion profile supports integration into ISO/IEC 17025-accredited workflows where extraction reproducibility is traceable to defined mechanical parameters—not thermal variables. No internal heating or cooling elements are present; therefore, it does not fall under FDA 21 CFR Part 11 requirements for temperature-controlled data integrity—but full audit-trail capability is maintained via external LIMS integration through RS-232 or optional USB logging.

Software & Data Management

The F10-3000 operates as a standalone instrument with embedded firmware controlling all motion and timing functions. Parameter settings—including frequency setpoint, tilt angle (if enabled), and timer duration—are stored in non-volatile memory and persist after power cycling. For GLP/GMP-aligned labs, optional data export modules (DRETOP Datalogger Pro v2.1, sold separately) provide timestamped CSV output of runtime logs, including start/stop timestamps, actual frequency deviation (<±1.5% full scale), and cycle count. These logs comply with ALCOA+ principles when archived alongside analytical test reports. No cloud connectivity or proprietary software installation is required for basic operation.

Applications

• Environmental analysis: EPA Methods 3510C (phenols), 3540C (pesticides), and 3550C (PAHs) requiring standardized shaking of aqueous/organic biphasic systems
• Food and feed testing: AOAC 2007.01 (mycotoxin extraction), ISO 14501 (fat-soluble vitamin recovery), and CEN/TS 15503-4 (phthalate migration studies)
• Agricultural residue analysis: Extraction of organophosphates and neonicotinoids from soil homogenates per SANTE/11813/2017 guidelines
• Pharmaceutical excipient screening: Solvent partitioning studies for log P determination under USP <467> residual solvent protocols
• Academic research: Kinetic modeling of mass transfer coefficients in liquid–liquid systems using synchronized multi-funnel sampling

FAQ

Does the F10-3000 include temperature control?

No. This model is a non-thermostatic shaker intended for ambient-temperature extraction protocols. For temperature-regulated applications, DRETOP offers the F10-3000T variant with Peltier-based cooling/heating modules.
Can I use glass funnels larger than 3000 mL?

The mechanical design and clamping geometry are validated for up to 3000 mL. Larger vessels require custom bracket engineering and static load verification—contact DRETOP Technical Support for feasibility assessment.
Is the oscillation motion sinusoidal or linear?

It produces near-linear reciprocating motion with minimal harmonic distortion (<3% THD), achieved via optimized crank-slider kinematics—critical for reproducible interfacial shear in biphasic systems.
What maintenance intervals are recommended?

Lubrication of the main drive bearing is required every 12 months or 2000 operating hours; belt tension inspection every 6 months. A full calibration certificate (motion amplitude/frequency traceability to NIST-traceable standards) is available upon request.
How is compliance with laboratory quality systems documented?

Each unit ships with a Factory Acceptance Test (FAT) report verifying amplitude linearity, frequency accuracy, and timer repeatability. IQ/OQ documentation templates compliant with ISO/IEC 17025 Annex A.2 are provided in English upon order confirmation.
