Detelogy MultiPro-V20 Intelligent Vacuum Parallel Concentrator

Overview

The Detelogy MultiPro-V20 Intelligent Vacuum Parallel Concentrator is an engineered solution for high-throughput, reproducible solvent removal under controlled reduced-pressure conditions. It operates on the principle of simultaneous vacuum-assisted evaporation combined with precise water-bath heating and orbital shaking—enabling rapid, uniform concentration of up to 20 samples in parallel. Unlike single-sample rotary evaporators or nitrogen blow-down systems, the MultiPro-V20 eliminates sequential processing bottlenecks while maintaining analytical integrity across diverse sample matrices. Its design integrates Couette-flow-inspired agitation, optimized vapor path geometry, and condensate management via dual-stage condensation—ensuring minimal analyte loss, high recovery (>95% for volatile organics under validated protocols), and compliance with method requirements for trace-level quantification in regulated environments.

Key Features

• 20-position parallel processing with independent sealing and fluidic isolation per vial—prevents cross-contamination during heterogeneous batch runs.
• PID-controlled water bath (0–100 °C, ±0.1 °C accuracy) featuring triple-sided transparent borosilicate glass chamber for real-time visual monitoring of sample meniscus, foam behavior, and endpoint detection.
• Intelligent vacuum regulation with 20-step programmable gradient control; supports method-specific pressure ramping to accommodate volatility gradients across multi-analyte extractions.
• 10.1″ industrial-grade capacitive touchscreen with graphical interface displaying live curves for vacuum level, bath temperature, and oscillation frequency—enabling dynamic parameter adjustment without interrupting operation.
• Dual optional condenser tower configuration enhances solvent recovery efficiency for low-boiling solvents (e.g., dichloromethane, ethyl acetate) and reduces environmental emissions.
• Corrosion-resistant diaphragm vacuum pump rated for continuous duty with halogenated, acidic, and amine-containing vapors—validated per ISO 8573-1 Class 3 particulate and oil-free air specifications.
• Integrated auto-fill and auto-drain system controlled directly from the HMI—eliminates manual water handling and supports unattended overnight operation.
• Multi-color status illumination synchronized with operational phases (e.g., blue = equilibration, amber = active evaporation, green = endpoint reached) for at-a-glance workflow assessment.

Sample Compatibility & Compliance

The MultiPro-V20 accommodates standard conical-bottom glass concentrator tubes (50 mL, 100 mL, 200 mL, and 250 mL), all constructed from ASTM E438 Type I, Class A borosilicate 3.3 glass. Its modular sealing architecture supports both screw-cap and O-ring clamp configurations, ensuring compatibility with legacy labware. The system meets mechanical safety requirements per IEC 61010-1:2010 and electromagnetic compatibility standards EN 61326-1:2013. For regulated laboratories, it supports 21 CFR Part 11-compliant data integrity when used with DTLabs software—providing electronic signatures, immutable audit trails, and timestamped method execution logs. All stored methods and run records include operator ID, instrument serial number, environmental metadata (ambient temp/humidity), and full parameter history—fully traceable for GLP/GMP audits.

Software & Data Management

Embedded firmware enables storage of up to 32 user-defined concentration protocols, each supporting up to 20 vacuum/temperature/time segments. All parameters—including setpoints, actuals, alarms, and event timestamps—are logged continuously and exportable in CSV or PDF format via USB 2.0 interface. The DTLabs mobile application (iOS/Android) provides secure TLS 1.2–encrypted remote access: users can initiate runs, monitor real-time curves, receive push notifications upon completion or fault conditions, and download full session reports. Data export files include embedded digital signatures and SHA-256 hash verification—ensuring authenticity and integrity for regulatory submissions. Optional integration with LIMS via RESTful API enables automated job dispatch and result ingestion.

Applications

The MultiPro-V20 is routinely deployed in accredited testing laboratories performing residue analysis per AOAC 2007.01, EPA Method 525.3, and EU SANTE/11312/2021. Key use cases include: post-extraction clean-up of pesticide multiresidue extracts in food commodities; concentration of PAHs and PCBs from soil and water extracts prior to GC-MS analysis; preparation of pharmaceutical impurity standards from synthetic reaction mixtures; and high-volume sample throughput in environmental monitoring programs requiring EPA 8270-compliant workflows. Its consistent thermal profile and minimized surface-to-volume ratio make it especially suitable for thermolabile compounds such as mycotoxins, vitamins, and certain oligonucleotides.

FAQ

What vacuum levels can the MultiPro-V20 achieve?
The integrated diaphragm pump delivers a base pressure of ≤5 mbar (absolute) under standard conditions; final operating pressure is user-programmable between 5–100 mbar depending on solvent boiling point and sample sensitivity.
Is the water bath fluid circulation forced or passive?
The bath uses passive convection only—no internal pump or impeller—to eliminate contamination risk and ensure silent, maintenance-free operation.
Can the instrument be validated for GxP environments?
Yes. IQ/OQ documentation templates are provided, and the system supports calibration traceability to NIST-traceable temperature and pressure standards.
Does the system support external temperature probes for direct sample monitoring?
No—sample temperature is inferred from bath setpoint and empirical correlation; direct immersion probes are not supported due to interference with agitation and sealing integrity.
How is maintenance performed on the condenser unit?
The condenser assembly is tool-free detachable; cleaning requires only deionized water rinse and air drying—no descaling agents or ultrasonic treatment needed.
