Overview
The JEIO TECH RS-1 Vertical Reciprocating Separatory Funnel Shaker is a purpose-engineered laboratory instrument designed for consistent, reproducible extraction and phase separation workflows in analytical chemistry, environmental testing, pharmaceutical QC, and academic research laboratories. Unlike orbital or rotary shakers, the RS-1 employs a precisely controlled vertical reciprocating motion—characterized by linear up-and-down displacement along a fixed axis—to generate uniform mechanical agitation within separatory funnels. This motion minimizes vortex formation and splashing while maximizing interfacial contact between immiscible liquid phases, thereby enhancing extraction efficiency and repeatability. The device operates without temperature control (ambient-only operation), making it suitable for room-temperature extractions where thermal stability is not required but mechanical consistency is critical.
Key Features
- Vertical reciprocating oscillation mechanism with adjustable frequency from 50 to 300 rpm, enabling optimization across diverse solvent systems and viscosity ranges.
- Fixed stroke length of 40 mm ensures consistent mechanical energy input per cycle, supporting method standardization across batches and operators.
- Integrated LED digital display provides real-time visibility of set parameters—including speed and remaining time—enhancing operational transparency and reducing user error.
- Dual-sided platform configuration accommodates up to 10 standard separatory funnels (5 per side), each secured via standardized clamp assemblies compatible with common glassware sizes (e.g., 500 mL, 1 L, 2 L).
- Programmable timer with dual-mode functionality: discrete 1–60 minute intervals or uninterrupted continuous operation, with audible end-of-cycle alert and automatic shutdown.
- Robust steel frame construction and balanced drive system ensure low-vibration performance and long-term mechanical reliability under repeated loading conditions.
Sample Compatibility & Compliance
The RS-1 is compatible with borosilicate glass and PTFE-coated separatory funnels ranging from 125 mL to 2 L capacity. Its clamping geometry supports both conical and cylindrical neck designs, and load distribution across six independent platforms maintains structural integrity even at maximum rated capacity (3.0 kg per side). While the instrument itself does not incorporate regulated temperature control, its mechanical design conforms to IEC 61010-1 safety standards for laboratory electrical equipment. It is routinely deployed in workflows aligned with ASTM D3418 (standard test method for thermal transitions of polymers) and EPA Method 3510C (liquid-liquid extraction), where defined agitation parameters are essential for data traceability and inter-laboratory comparability.
Software & Data Management
The RS-1 operates as a standalone hardware unit with no embedded software or connectivity interfaces. All parameter settings are entered manually via front-panel controls and retained only during active operation; no data logging, audit trail, or electronic record storage is performed. As such, it meets the functional requirements of GLP-compliant environments where manual entry into bound lab notebooks or LIMS-integrated protocols is standard practice. For laboratories requiring 21 CFR Part 11 compliance, external documentation of speed, duration, and operator identity must be maintained independently per run.
Applications
- Acid-base and solvent-based liquid-liquid extractions in organic synthesis and natural product isolation.
- Heavy metal recovery and speciation analysis in wastewater and soil leachate testing (e.g., EPA 6020B).
- Residue analysis of pesticides and veterinary drugs in food matrices per AOAC Official Methods.
- Pretreatment steps in sample preparation workflows prior to GC-MS, HPLC, or ICP-MS analysis.
- Standardized shaking protocols in teaching laboratories for undergraduate chemistry and environmental science curricula.
FAQ
What types of separatory funnels can be mounted on the RS-1?
Standard tapered-neck glass funnels from 125 mL to 2 L capacity, including those conforming to ASTM E288 and ISO 1042 specifications, are fully supported.
Is the RS-1 suitable for use with volatile or hazardous solvents?
Yes—its sealed motor housing and non-sparking drive components meet Class I, Division 2 electrical safety criteria when operated in properly ventilated fume hoods.
Can the oscillation direction be reversed or adjusted horizontally?
No—the RS-1 delivers strictly vertical reciprocating motion; horizontal or orbital modes are not available.
Does the RS-1 include calibration documentation or traceable certification?
Factory calibration certificates for speed accuracy (±2 rpm tolerance) and timer fidelity (±0.5% deviation) are available upon request and may be included with delivery for regulated applications.
How is maintenance performed on the RS-1?
Routine maintenance consists of periodic inspection of clamp integrity, lubrication of linear guide rails every 6 months, and verification of belt tension using the included service manual (document number: RS-1-MAINT-EN v2.1).
