This refurbished Waters Delta Prep 4000 preparative chromatography system comes with waters prep LC Controller, Waters 2487 Dual λ Absorbance Detector and Waters Prep Pump. The Waters PrepLC 4000 system provides high resolution, preparative capability –from hundreds of milligrams to grams per run with the best price/performance ratio of any preparative HPLC system.
This Waters PrepLC 4000 system is ideal for dedicated preparative LC applications, where high volume sample loads may be purified, fractions collected and the column automatically flushed prior to the next run. This system can also be used for checking fractions for purity – all on the same system.
This refurbished Waters Prep 4000 System is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included. Multiple available.
