EYELA TVE-1100A/B Vortex Evaporative Concentrator

Overview

The EYELA TVE-1100A/B Vortex Evaporative Concentrator is an engineered solution for parallel, low-temperature solvent removal from multiple biological, pharmaceutical, and analytical samples under controlled vacuum conditions. Unlike conventional rotary evaporators or nitrogen blow-down systems, the TVE series employs a unique vortex-assisted vacuum evaporation principle: simultaneous orbital oscillation (100–1100 rpm) induces dynamic surface turbulence in each sample vessel, significantly increasing the effective evaporation area while suppressing bumping and foaming—critical for heat-sensitive analytes such as peptides, nucleic acids, metabolites, and unstable small molecules. The system integrates water-bath heating (not dry-block or air-heating) for uniform thermal transfer, enabling reproducible concentration kinetics comparable to benchtop rotary evaporators—but with enhanced scalability and reduced cross-contamination risk. Its modular design supports two primary configurations: the TVE-1100A for standard glass or plastic test tubes (Φ12–Φ18 mm × 100–180 mm), and the TVE-1100B optimized for PP centrifuge tubes (29 mm OD × 110 mm). Both share a common base unit, allowing seamless method transfer across vessel types via interchangeable adapters.

Key Features

• Vortex-driven evaporation: Orbital oscillation (3 mm amplitude) generates stable, laminar vortex flow—enhancing mass transfer without mechanical agitation-induced shear stress on labile biomolecules.
• Integrated warm-air shroud: A thermostatically regulated air jacket surrounds the vacuum manifold and gas lines, maintaining line temperature above solvent dew point to prevent condensate formation and eliminate carryover contamination.
• Precision water-bath heating: Stainless-steel bath with PID-controlled circulation delivers uniform thermal input across all vessels; temperature stability maintained within ±0.2°C over full operating range (ambient +5°C to 60°C for TVE-1100A).
• Chemically inert fluid path: All wetted components—including vacuum/vent ports, tubing interfaces, and adapter seals—are constructed from PTFE, PP, Viton®, silicone rubber, or borosilicate glass to ensure compatibility with aggressive solvents (e.g., chloroform, acetonitrile, ethyl acetate) and acidic/basic extracts.
• Modular multi-vessel support: Accommodates 1–8 samples simultaneously; adapters enable rapid switching between tube formats (straight, flip-top, screw-cap, ground-joint) without tooling or recalibration.
• Robust vacuum interface: Standard 10 mm OD vacuum/vent ports facilitate integration with external diaphragm or oil-free scroll pumps; optional pressure control modules support programmable ramped vacuum profiles.

Sample Compatibility & Compliance

The TVE concentrator is routinely deployed in GLP-compliant laboratories for sample preparation prior to LC-MS, GC-MS, ICP-MS, and ELISA workflows. Its design conforms to key requirements of ISO/IEC 17025:2017 (clause 6.4.3 on equipment suitability) and supports audit-ready operation when paired with validated vacuum pumps and calibrated temperature probes. While the instrument itself does not carry CE marking for IVD use, its material certifications (USP Class VI elastomers, FDA-compliant PP/PTFE) meet extractables and leachables criteria for residual solvent analysis per USP and ICH Q5C. Vessel compatibility extends to certified low-binding polypropylene tubes, silanized glass vials, and amber-walled containers—enabling light-sensitive applications without modification.

Software & Data Management

The TVE-1100A/B operates as a standalone benchtop device with analog-digital hybrid controls: a front-panel encoder adjusts speed and temperature, while LED indicators provide real-time status feedback (heating active, vacuum engaged, oscillation running). Though no proprietary software is bundled, the system’s analog outputs (0–5 V temperature and rpm signals) are compatible with third-party data loggers (e.g., Omega OM-DAQPRO, Keysight 34972A) for 21 CFR Part 11–compliant electronic recordkeeping when integrated into validated laboratory information management systems (LIMS). Users may configure time-stamped run logs—including start/end timestamps, setpoints, and ambient conditions—to satisfy internal SOPs for sample traceability and process repeatability.

Applications

• High-throughput concentration of plasma, serum, urine, and tissue homogenates prior to targeted metabolomics or proteomics analysis.
• Parallel solvent exchange (e.g., methanol → water) in oligonucleotide purification and synthetic peptide cleavage workflows.
• Pre-concentration of environmental water extracts (EPA Method 1694) and pesticide residues (AOAC 2007.01) prior to GC-ECD or LC-MS/MS quantification.
• Rapid drying of calibration standards and QC reference materials without thermal degradation or oxidation.
• Removal of volatile organic solvents from natural product isolates during phytochemical fractionation.

FAQ

Can the TVE-1100A accommodate both glass and plastic tubes simultaneously?

Yes—provided they fall within the specified outer diameter range (Φ12–Φ18 mm) and height (100–180 mm); however, thermal expansion differences between materials may require minor optimization of bath temperature setpoint.
Is the water bath filled with deionized water only, or can other heat-transfer fluids be used?

The bath is designed exclusively for deionized or distilled water; glycols or oils are incompatible due to pump seal and heater element specifications.
Does the system include vacuum pump and cold trap?

No—these are external accessories; EYELA recommends pairing with oil-free diaphragm pumps (e.g., NVR-1000 series) and inline PTFE-coated cold traps for optimal solvent recovery and pump protection.
How is method transfer validated between TVE-1100A and TVE-1100B configurations?

Validation requires comparative recovery studies using spiked matrix samples, measuring % recovery, RSD (<5%), and residual solvent levels (per ICH Q3C) across three independent runs per configuration.
What maintenance intervals are recommended for long-term reliability?

Daily: Drain and wipe bath chamber; weekly: Inspect O-rings and gas line integrity; annually: Calibrate temperature sensor against NIST-traceable reference thermometer and verify oscillation speed with optical tachometer.
