INNOTEG EasyPrep Eco Economical Flash Chromatography System

Overview

The INNOTEG EasyPrep Eco is a compact, integrated flash chromatography system engineered for reliable, entry-level preparative separation in synthetic and analytical laboratories. It operates on the principle of medium-pressure liquid chromatography (MPLC), utilizing gradient or isocratic elution to resolve complex mixtures based on differential partitioning between stationary and mobile phases. Designed specifically for chemists without dedicated chromatography training, the system integrates a dual-piston high-precision pump, a solid-state UV-Vis detector with selectable fixed-wavelength LEDs (254 nm, 280 nm, 365 nm, and optional 405/600 nm), and an automated fraction collector—all coordinated via an embedded touchscreen workstation. Its pressure-limited architecture (max 1.0 MPa / ~10 bar) ensures compatibility with standard silica and reversed-phase cartridges (4–80 mm ID) and packed glass columns, making it suitable for rapid purification of reaction crude mixtures, natural product isolates, and intermediate compounds across drug discovery and process development workflows.

Key Features

• Integrated hardware platform: Synchronized pump, UV-Vis detector, and fraction collector controlled from a single intuitive interface—no external PC required.
• LED-based optical detection: Solid-state light sources replace traditional tritium lamps; eliminate lamp aging, warm-up delays, and scheduled replacement cycles—reducing long-term operational cost and downtime.
• No-valve pump design: Dual-piston reciprocating pump with passive check valves omitted; minimizes clogging risk with viscous or particulate-laden solvents (e.g., DCM-containing eluents) and eliminates routine valve maintenance.
• Rapid method deployment: Supports digital workflow integration—TLC image capture (via smartphone or USB camera), automatic R_f analysis, and gradient method generation using built-in algorithmic logic; methods are directly executable without manual parameter tuning.
• Compact footprint: Dimensions approx. 320 × 300 × 420 mm (W × D × H); occupies <70% of A4 paper area; total mass ≈ 16 kg—enables placement inside fume hoods, gloveboxes, or shared benchtop environments without structural reinforcement.
• Gradient flexibility: User-selectable “Standard” (linear, 10–20 min) or “Fast” (shallow, <8 min) profiles; real-time flow/pressure monitoring with automatic flow compensation under backpressure variation.

Sample Compatibility & Compliance

The EasyPrep Eco accommodates common organic solvents (hexane, EtOAc, DCM, MeOH, ACN, water, and buffered aqueous phases) and supports both normal-phase (silica, amino, cyano) and reversed-phase (C18, C8) stationary phases. It complies with general laboratory safety standards for low-pressure solvent handling (IEC 61010-1). While not certified for GMP manufacturing environments, its data integrity features—including timestamped method logs, detector signal archives, and fraction mapping metadata—support GLP-aligned documentation practices. The system does not include 21 CFR Part 11-compliant electronic signatures or audit trails; however, raw chromatogram files (.csv, .txt) and method parameters are exportable for external validation and regulatory submission support.

Software & Data Management

The onboard Linux-based control software provides touch-optimized operation with three primary modes: Method Setup, Run Execution, and Post-Run Review. All chromatograms, UV traces, fraction collection maps, and method parameters are stored locally on internal eMMC storage (8 GB) and exportable via USB 2.0 port. No cloud connectivity or remote access capability is implemented—ensuring full data sovereignty. Software updates are delivered via offline firmware packages; version history and changelogs are maintained in the Help menu. Batch processing is supported through sequential method queuing, with inter-run delay timers and auto-shutdown scheduling.

Applications

This system is routinely deployed in academic and industrial settings for: isolation of synthetic intermediates in medicinal chemistry campaigns; purification of natural product extracts (alkaloids, flavonoids, terpenes); desalting and buffer exchange of peptides and small biomolecules; parallel purification of Suzuki/Miyaura cross-coupling products; and preparative-scale cleanup prior to NMR or MS analysis. Its robustness with chlorinated solvents and tolerance for moderate sample loading (up to 500 mg on 25 mm ID columns) make it especially suited for iterative synthesis labs where speed, reproducibility, and minimal operator intervention are prioritized over ultra-high resolution.

FAQ

Is the EasyPrep Eco compatible with gradient methods using acetonitrile/water mobile phases?
Yes—reversed-phase gradients are fully supported; ensure column and tubing materials are rated for ACN exposure and system backpressure remains below 1.0 MPa.
Can I use my own TLC plates and imaging setup with the method-generation feature?
Yes—the software accepts standard JPEG/PNG images captured under UV or visible light; R_f values are extracted via contrast-based edge detection and mapped to recommended solvent strength indices.
Does the system support pH-sensitive fractions or light-sensitive compounds?
Fraction collection is triggered by UV absorbance threshold or time-based intervals; optional amber glass tubes and inert gas purging (via external manifold) can be implemented at the user’s discretion.
What maintenance is required beyond routine solvent filtration and column conditioning?
None—no consumable valves, seals, or lamps require periodic replacement; pump pistons and seals are rated for >10,000 hours of continuous operation under typical lab conditions.
Is method transfer possible between EasyPrep Eco and analytical HPLC systems?
Retention time correlation is approximate due to differences in column efficiency and extra-column volume; however, gradient slope and solvent selectivity relationships remain broadly transferable for scouting purposes.
