Overview
The IKA RV 3 FLEX Rotary Evaporator is a precision-engineered benchtop system designed for reliable solvent removal, concentration, and gentle distillation under reduced pressure. Based on the fundamental principle of rotary evaporation—where sample rotation increases surface area while vacuum lowers boiling points—the RV 3 FLEX enables controlled, reproducible evaporation across diverse sample matrices. Its modular architecture, compliant with DIN EN 60529 (IP20) safety standards and rated for continuous operation within ambient conditions of 5–40 °C and ≤80% relative humidity, makes it suitable for routine use in R&D laboratories, QC/QA environments, and pilot-scale production settings across pharmaceutical, chemical, and biotechnology sectors.
Key Features
- 4 L heating bath with digital temperature display and ergonomic lift handle for safe, intuitive handling
- Manually operated vertical lift mechanism with adjustable endpoint positioning—ensuring consistent condenser alignment and preventing mechanical stress on glassware
- Dual-lock safety system: secondary lock on the evaporation tube features integrated red visual indicator when disengaged, minimizing risk of accidental detachment
- Single-hand operation design optimized for workflow efficiency in high-throughput labs
- Adjustable motor tilt angle (±15°) to accommodate varying flask geometries and improve film uniformity during rotation
- Stepless speed control with calibrated analog scale; precise DC motor delivers stable rotation from 20 to 300 rpm (±1 rpm accuracy below 100 rpm; ±1% above)
- 24 V low-voltage motor drive enhances electrical safety and reduces electromagnetic interference in sensitive instrumentation zones
- Dedicated flask-release knob secures the evaporation flask during both operation and removal—eliminating slippage or misalignment
- Standard 1500 cm² cooling surface via optional triple-layer condenser, compatible with full RV10-series glassware (including 1 L, 2 L, and 4 L flasks)
Sample Compatibility & Compliance
The RV 3 FLEX supports a broad range of solvents—including water, ethanol, acetone, ethyl acetate, and chlorinated hydrocarbons—across viscosity ranges typical of crude extracts, reaction mixtures, and formulated APIs. Its stainless-steel heating bath and PTFE-coated components resist corrosion from acidic or basic media. The system complies with CE marking requirements and conforms to IEC 61010-1 for laboratory electrical equipment safety. While not intrinsically explosion-proof, its 24 V motor and absence of internal ignition sources permit use in non-hazardous zone environments per ATEX Directive 2014/34/EU guidelines. All operational parameters are traceable and documentable, supporting GLP-compliant workflows when integrated into validated lab management systems.
Software & Data Management
As a standalone analog-digital hybrid instrument, the RV 3 FLEX does not feature embedded microprocessor control or network connectivity. However, its analog temperature readout and calibrated speed scale enable manual logging compatible with paper-based or electronic lab notebooks (ELN). Users may integrate the unit into broader digital infrastructure via external data acquisition modules—for instance, connecting PT100 probes or vacuum transducers to third-party SCADA or LIMS platforms. For audit-ready documentation, the device supports time-stamped parameter recording aligned with FDA 21 CFR Part 11 principles when paired with compliant ELN software and role-based access controls.
Applications
- Solvent recovery and concentration of natural product extracts in phytochemistry labs
- Removal of volatile reagents post-Suzuki coupling or Grignard reactions in synthetic organic chemistry
- Lyophilization pre-concentration steps prior to freeze-drying of protein formulations
- Bulk solvent stripping in small-batch API purification under cGMP-aligned QC protocols
- Distillative fractionation of heat-sensitive compounds (e.g., terpenes, flavonoids) using controlled bath temperature ramping
- Educational demonstrations of phase equilibria, Raoult’s law, and vacuum thermodynamics in university teaching labs
FAQ
Is the RV 3 FLEX compatible with vacuum controllers or automated pressure regulation systems?
Yes—its standard 1/4″ ISO-KF vacuum port accepts common vacuum hose fittings and interfaces seamlessly with external vacuum controllers (e.g., IKA RV 10 control units or third-party PID-regulated pumps) for programmable pressure ramping.
What glassware configurations are supported beyond the standard 4 L flask?
All RV10-series accessories are mechanically and dimensionally compatible, including 1 L round-bottom flasks, 2 L short-path distillation kits, and vertical condensers with coolant circulation ports.
Does the heating bath support external temperature probe feedback for tighter control?
No—the built-in PT100 sensor provides direct bath temperature monitoring and regulation; no external probe input is available. For applications requiring sample-specific thermal profiling, users should employ immersion thermocouples independent of the evaporator control loop.
Can the unit be used continuously for extended periods (e.g., overnight runs)?
Yes—provided ambient conditions remain within specifications (5–40 °C, ≤80% RH) and cooling water flow (if using circulating chiller) is uninterrupted; however, unattended operation requires local risk assessment and adherence to institutional safety policies.
Is service documentation and spare parts availability guaranteed outside Germany?
IKA maintains authorized service partners across North America, EMEA, and APAC regions; all technical manuals, calibration certificates, and OEM spare parts—including seals, bath liners, and motor assemblies—are accessible through regional distributors with ≤5-business-day lead times.
