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 reat condition. It has been tested at SpectraLab Scientific.
 
A 90 day warranty is included.
