Testing performed by our in-house service team:
The CombiFlash EZ Prep UV-VIS Flash Chromatography System passed all tests and was found to be fully functional:
• We verified the power supply and initialization.
• We calibrated the touch screen interface.
• We assessed the accuracy of arm movement.
• We confirmed the RFID column detection.
• We evaluated the waste and source-level sensing.
• We clean and inspect the check valves.
• We tested the manual control functionality.
• We checked the HPLC prime operation for consistency.
• We analyzed the gradient performance.
• We verified the UV detection using a sodium iodide solution.
• We perform the PHE/N-BBZ test to confirm correct gradient behavior.

Instrument Overview:
• Teledyne ISCO CombiFlash EZ Prep UV-VIS Preparative Flash Chromatography System integrates prep-scale flash and HPLC modes.
• Equipped with dual piston pumps for high-precision gradient control across wide flow-rate ranges.
• UV-VIS detector covers multiple wavelengths, enabling selective detection and accurate fraction triggering.
• Supports loading of crude mixtures from milligrams up to tens of grams with high recovery rates.
• Pressure-rated hardware accommodates high backpressures for rapid purification of diverse compounds.
• The system enhances efficiency in laboratories focused on organic synthesis and compound isolation.

Instrument Application:
• Purification of synthetic organic compounds after reaction steps
• Isolation of natural products from plant or microbial extracts
• Scale-up of lead molecules for medicinal chemistry studies
• Separation of closely related analogs or isomers for characterization

The Key Features:
• Integrated flash chromatography and preparative HPLC modes
• Dual piston gradient pumps with programmable flow rates
• UV-VIS detector covering a wide wavelength range
• Fraction collector module (standard rack, limited capacity)
• Software interface for instrument control and basic data handling

WHY DO CUSTOMERS MAKING CRITICAL LAB PURCHASES CHOOSE TO ORDER CHROMATOGRAPHY SYSTEMS FROM US?

They want to ensure all pump heads, seals, and check valves have been tested for consistent pressure generation and stable flow rates, preventing gradient drift, pulsation, or baseline instability.
________________________________________
They want peace of mind knowing the system has been fully flushed, primed, and run through gradient and collection tests under realistic purification conditions.
________________________________________
They want to ensure expected retention times for verification standards fall within tolerance, confirming that solvent routing, column integrity, and pump calibration are functioning within manufacturer specifications.
________________________________________
They want to avoid baseline instability, incorrect solvent mixing, or poor fraction resolution caused by untested pumps, misconfigured detectors, or software timing errors, issues that often go undetected until critical purification work is lost.
________________________________________
They want assurance that fraction collectors, diverter valves, and switching modules operate correctly under pressure and respond precisely to signal triggers, avoiding miscollection or cross-fraction contamination.
________________________________________
They want to ensure the UV lamp has been checked for remaining life and replaced if needed, so the system generates good data and is ready to use the same day it is installed.
________________________________________
They want peace of mind, knowing their instrument is backed by a warranty from a company that can stand behind it.
