Organomation S-EVAP-RB Series Parallel Evaporator

Overview

The Organomation S-EVAP-RB Series Parallel Evaporator is a precision-engineered, benchtop solvent removal system designed for high-throughput, reproducible concentration of multiple samples under controlled thermal and vacuum conditions. Utilizing a water-jacketed heating bath coupled with vertical condensation geometry and optional vacuum integration, the system operates on the principle of simultaneous rotary evaporation—where solvent volatility is enhanced by regulated temperature, reduced pressure (when equipped), and efficient vapor condensation. Unlike single-vessel rotovaps, the S-EVAP-RB series maintains identical thermal profiles and vapor path lengths across all sample positions, minimizing inter-sample variability and eliminating manual repositioning. Its modular architecture supports both ambient-pressure evaporation (for solvents boiling ≤65 °C) and vacuum-assisted concentration (for solvents up to 90 °C), delivering ≥97% solvent recovery efficiency without cross-contamination. Engineered for laboratory environments requiring routine compliance with environmental stewardship standards, the system meets ISO 14000 criteria for energy-efficient, low-emission solvent handling.

Key Features

• Three configurable configurations: 5-, 8-, and 10-position independent recovery units, each supporting parallel processing of discrete samples
• Stainless steel circular water bath with precise mechanical or digital temperature control (30–100 °C; ±2 °C accuracy standard; ±0.5 °C optional on 10-position model)
• Vertically oriented solvent recovery column that rotates freely on its base—enabling unobstructed access to rear-mounted samples without disassembly
• Dual-capacity solvent bottle compatibility: standardized flat-bottom round flasks in 250 mL and 500 mL volumes, optimized for uniform heat transfer and minimal residue retention
• Integrated safety subsystems including automatic water-level sensor, high-temperature cutoff switch, and fault-interrupt circuitry; optional GFCI plug available for enhanced electrical protection
• UL/cUL certification confirms adherence to North American electrical safety standards (UL 61010-1); no external venting required for standard operation
• Modular vacuum interface (-V option) and nitrogen purge capability (-N option) enable method flexibility for oxygen-sensitive or high-boiling-point analytes

Sample Compatibility & Compliance

The S-EVAP-RB accommodates a broad range of sample matrices—including concentrated acids, caustic bases, lipid-rich extracts, and viscous organic solutions—without degradation of glassware or thermal instability. All wetted components are constructed from borosilicate glass (including Inverted Hopkins condensers, 375 mm length) and chemically resistant stainless steel. Each collection vessel is sealed independently, preventing carryover between runs and supporting trace-level analytical workflows. The system’s closed-loop solvent recovery design aligns with ISO 14000 environmental management protocols and reduces laboratory VOC emissions. For regulated quality environments, the digital temperature display (on -V/-N models) supports audit-ready documentation; while not inherently 21 CFR Part 11 compliant, the instrument may be integrated into validated workflows via external data logging systems meeting GLP/GMP requirements.

Software & Data Management

The base S-EVAP-RB series operates via analog or digital front-panel controls—no embedded software or network connectivity is included. Temperature setpoints and operational status are displayed via LED readouts (on models with digital controllers). For laboratories requiring electronic recordkeeping, third-party data acquisition modules can interface with the unit’s analog output signals (e.g., 4–20 mA temperature feedback) or integrate via relay-controlled start/stop triggers. While the device does not feature built-in audit trails or user authentication, its mechanical simplicity and deterministic thermal response support straightforward IQ/OQ validation per ASTM E2500 and ISO/IEC 17025 guidelines.

Applications

This evaporator is routinely deployed in QC/QA laboratories across pharmaceutical development (residual solvent analysis per USP ), environmental testing (EPA Method 502.2, 525.3), agrochemical residue screening, natural product isolation, and forensic toxicology. It is especially suited for concentrating large-volume extractions prior to GC-MS or LC-MS analysis, where preservation of thermally labile compounds and quantitative recovery are critical. The 10-position configuration is widely adopted in contract research organizations performing parallel method development for solvent optimization studies.

FAQ

What solvent boiling points can be effectively recovered using the S-EVAP-RB without vacuum?
Solvents with boiling points ≤65 °C (e.g., dichloromethane, ethyl acetate, acetone) achieve full recovery under ambient-pressure operation.
Is the water bath compatible with corrosive heating media such as acidified water or salt solutions?
No—the bath is designed exclusively for deionized or distilled water; use of aggressive media voids warranty and risks heater corrosion.
Can I replace the standard Inverted Hopkins condenser with a different type?
Yes, provided the replacement maintains identical ground-glass joint dimensions (24/40 or 29/42 depending on flask size) and vertical orientation for gravity-assisted condensate return.
Does the system require external cooling water for condensation?
No—all models use air-cooled condensers; no chiller or tap-water connection is needed.
How is calibration verified during routine maintenance?
Users perform temperature verification using a NIST-traceable thermometer immersed at bath center; deviation beyond ±2 °C warrants recalibration of the controller or sensor replacement.
