BFY-2 Vertical Separatory Funnel Shaker by Beifen Sanpu

Overview

The BFY-2 Vertical Separatory Funnel Shaker is an engineered laboratory instrument designed to automate liquid-liquid extraction and homogenization procedures in analytical chemistry workflows. It operates on a precisely controlled vertical or adjustable-angle oscillation principle—utilizing eccentric drive mechanics to generate reproducible sinusoidal motion—enabling consistent phase separation kinetics across multiple separatory funnels simultaneously. Unlike orbital or reciprocating shakers, the BFY-2’s vertically oriented motion minimizes emulsion formation and accelerates interfacial settling, particularly critical in environmental, food safety, and residue analysis where high recovery efficiency and phase clarity are mandated by method protocols (e.g., EPA Method 3510C, ISO 18337:2016). Its robust aluminum-alloy frame, corrosion-resistant stainless-steel platform, and sealed brushless DC motor ensure long-term stability under continuous operation in regulated laboratory environments.

Key Features

• Adjustable oscillation mode: vertical or tilt (0–20°), with engraved angular calibration for method-specific reproducibility
• Digital frequency display with closed-loop speed control; maintains ±1 rpm stability over full 0–350 rpm range
• Infinitely variable amplitude control (0–60 mm peak-to-peak), enabling optimization for low-viscosity solvents or high-density immiscible systems
• Programmable timer with 1-minute resolution, supporting durations from 1 minute to 99 hours—compatible with multi-step extraction protocols requiring sequential agitation and settling cycles
• Four independently mounted shaker plates, each accommodating 8–10 vessels via elastic, self-centering universal clamps—designed to secure standard glassware including separatory funnels (125–2000 mL), volumetric flasks, Erlenmeyer flasks, centrifuge tubes, and graduated cylinders without adapter kits
• Integrated polycarbonate safety shield with interlock switch, meeting IEC 61010-1:2010 requirements for Class II laboratory equipment
• Low-noise operation (<55 dB(A) at 1 m), suitable for shared lab spaces and GLP-compliant facilities

Sample Compatibility & Compliance

The BFY-2 supports standardized sample containers used in accredited testing laboratories, including those specified in AOAC Official Methods®, USP , and Chinese National Standards (e.g., GB/T 5009.x series). Its clamp geometry accommodates conical, cylindrical, and pear-shaped funnels without slippage—even during vigorous agitation of viscous matrices such as edible oils or sediment-laden soil extracts. The system complies with electromagnetic compatibility (EMC) requirements per GB/T 18268.1–2010 (equivalent to IEC 61326-1) and meets mechanical safety standards outlined in GB 4793.1–2007 (IEC 61010-1). While not certified for use in explosion-proof zones, it is routinely deployed in ISO/IEC 17025-accredited food testing labs conducting pesticide residue, heavy metal, and mycotoxin analyses under documented SOPs.

Software & Data Management

The BFY-2 operates as a standalone hardware platform with no embedded software or network interface—intentionally designed for simplicity, reliability, and auditability in regulated settings. All operational parameters (start time, duration, rpm, tilt angle) are set via front-panel rotary encoder and LED display; no firmware updates or data logging occur internally. This architecture eliminates validation complexity associated with electronic records and ensures full compliance with FDA 21 CFR Part 11 when used within paper-based or LIMS-integrated workflows. Users maintain traceability through manual logbook entries or integration with external timers and electronic lab notebooks (ELNs), aligning with GLP documentation practices for method validation and routine QC.

Applications

• Environmental analysis: Extraction of PAHs, PCBs, organochlorine pesticides, and phenolic compounds from water, soil, and sediment per EPA SW-846 Methods 3510C and 3520C
• Food safety testing: Quantitative recovery of benzoic acid (GB/T 12289), penicillin (GB/T 5009.185), cadmium (GB/T 5009.15), and HEMF aroma compounds from fruit juices, sauces, and fermented products
• Residue monitoring: Multi-residue extraction of carbamates, organophosphates, and neonicotinoids from vegetables and grains using ethyl acetate, diethyl ether, or hexane-based systems
• Lipid and natural product isolation: Recovery of caffeine from tea, lipids from seeds, and antioxidants from herbal matrices under controlled pH and temperature conditions
• Quality control in edible oil processing: Acid value determination, nickel/copper quantification in hydrogenated fats (GB/T 5009.77), and rancidity assessment via peroxide value extraction steps

FAQ

Can the BFY-2 accommodate 2000 mL separatory funnels without modification?
Yes—the standard stainless-steel funnel rack supports up to four 2000 mL funnels per plate; custom rack configurations are available upon request.
Is the oscillation frequency calibrated and traceable to national standards?
Frequency accuracy is factory-verified against NIST-traceable tachometer references; calibration certificates are provided with each unit.
Does the BFY-2 support unattended overnight operation?
Yes—its 99-hour timer, thermal overload protection, and brushless motor design enable safe extended-run operation without supervision.
How is maintenance performed on the drive mechanism?
The eccentric cam assembly requires no periodic lubrication; only annual visual inspection of belt tension and clamp integrity is recommended per manufacturer guidelines.
Can the BFY-2 be validated for ISO/IEC 17025 accreditation?
Yes—it is routinely included in IQ/OQ protocols for extraction instrumentation; users may perform performance qualification using reference standards such as certified aqueous/organic phase separation test kits.
