LabTech Flex-MVP evo Automated Vacuum Parallel Concentrator

Overview

The LabTech Flex-MVP evo is an automated vacuum parallel concentrator engineered for high-throughput, reproducible solvent removal from multiple liquid samples under controlled thermal, vacuum, and mechanical agitation conditions. It operates on the principle of simultaneous rotary evaporation under reduced pressure—enhanced by precise orbital shaking and regulated heating—to accelerate solvent volatilization while minimizing analyte degradation or oxidation. Unlike conventional single-vessel evaporators or batch-mode systems requiring full system venting for sample handling, the Flex-MVP evo implements a per-channel isolated vacuum architecture. This enables real-time, non-interruptive addition or removal of individual samples during active concentration—preserving process continuity across remaining channels. Endpoint determination is achieved via 16 independent optical sensors utilizing near-infrared (NIR) absorption detection, which measures solvent level changes without interference from sample color, turbidity, or ambient lighting—ensuring robust volumetric endpoint accuracy across diverse matrices including colored extracts, biological fluids, and particulate-laden environmental digests.

Key Features

• 16-position parallel processing with independent vacuum control per channel—enabling selective sample access without system-wide pressure release
• NIR-based optical endpoint detection for each vessel, delivering consistent volume-defined termination (e.g., 1.0 mL ± 0.05 mL) regardless of sample optical properties
• Dual-tower cold trap condenser system: primary condensation for solvent vapor recovery + secondary adsorption stage for residual volatile organic compounds (VOCs) and acidic/alkaline off-gases
• Orbital shaking mechanism (0–300 rpm, adjustable) integrated with heated aluminum block (ambient to 100 °C, ±0.5 °C stability) to enhance mass transfer and prevent bumping
• Android-powered touchscreen interface with embedded firmware supporting parameter logging, gradient programming, and time-stamped operation history
• Modular cup holder design accommodating standard 50 mL and 200 mL borosilicate glass or PTFE-lined concentrator vessels—no tooling required for insertion/removal

Sample Compatibility & Compliance

The Flex-MVP evo is validated for use with aqueous, acidic, basic, and moderately organic solvent systems—including methanol, acetonitrile, ethyl acetate, dichloromethane, and hexane—commonly employed in EPA Method 1613, ISO 18857-1, AOAC 2007.01, and GB/T 5009 series workflows. Its sealed, channel-isolated manifold prevents cross-contamination between samples—a critical requirement for GLP-compliant residue analysis in food safety and environmental monitoring labs. All wetted surfaces contact only chemically inert materials (PTFE, borosilicate glass, stainless steel 316), ensuring compatibility with aggressive digestates from microwave-assisted acid digestion. The system supports 21 CFR Part 11–ready audit trail generation when connected to LabTech’s optional LIMS-integrated software suite, fulfilling documentation requirements for FDA-regulated QC/QA environments.

Software & Data Management

The onboard Android OS hosts LabTech’s ConcentrationSuite v3.2 firmware, providing real-time graphical display of temperature, vacuum pressure (range: 0.1–100 mbar, resolution: 0.1 mbar), and shake frequency across all 16 channels. Users may define multi-step protocols—including ramped heating profiles, staged vacuum reduction, and timed oscillation sequences—with automatic saving of method files and execution logs. All parameter changes are timestamped and user-annotated; raw data exports as CSV or PDF reports include metadata (operator ID, instrument serial number, calibration status). Optional network connectivity enables remote monitoring via secure HTTPS API and integration with laboratory information management systems (LIMS) using HL7 or ASTM E1384 standards.

Applications

The Flex-MVP evo serves laboratories performing routine and regulatory analyses requiring parallel sample preparation prior to GC-MS, LC-MS/MS, ICP-MS, or ELISA quantification. Typical applications include: pesticide residue analysis in fruits and vegetables (EN 15662); PAH and PCB extraction from soil and sediment (EPA 3540C/3550C); mycotoxin cleanup in cereals and feedstuffs (AOAC 2005.08); heavy metal speciation after HNO₃/HF digestion in clinical and environmental specimens; and oligonucleotide desalting in biopharmaceutical development. Its ability to maintain stable vacuum and temperature gradients across heterogeneous sample sets makes it particularly suited for inter-laboratory comparison studies governed by ISO/IEC 17025 accreditation requirements.

FAQ

How does the Flex-MVP evo achieve accurate endpoint detection without visible-light interference?
It employs near-infrared (NIR) optical sensors operating at wavelengths insensitive to chromophore absorption—enabling reliable meniscus detection in dark, turbid, or fluorescent samples.
Can the system handle viscous or foaming samples?
Yes—orbital shaking amplitude and frequency are independently adjustable per protocol, and the anti-bumping design of the conical cup geometry combined with gradual vacuum ramping minimizes foam formation and splashing.
Is the dual-tower cold trap serviceable without system shutdown?
The primary condenser tower is accessible via front-panel quick-release; the secondary adsorbent module is field-replaceable with <5-minute downtime and no vacuum pump isolation required.
What calibration documentation is provided?
Each unit ships with NIST-traceable temperature and pressure calibration certificates, plus optical sensor linearity verification report per channel.
Does the system support IQ/OQ/PQ validation packages?
LabTech provides GMP-aligned Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) templates compliant with Annex 11 and USP guidelines.
