Fine product but some initial problems.
organic chemistry research
the PuriFlash XS420 is fine, but some issues getting it up and running out of the box. Software debug was needed and a few components had to be replaced. Once initial troubles were past the instrument has been quite useful.

Purification of synthesis reaction mixtures, natural product extracts, proteins and peptides from mg to gram quantities are easily accomplished with the PuriFlash XS 420. The multi-wavelength UV-DAD (diode array detection) includes real-time full spectra scanning to confirm purity.
The heart of the instrument is the iQuat gradient HPLC pump, which provides a quaternary gradient plus a dedicated purge line (A+B+C+D, i). A ten-second isopropanol purge prepares the flow path for either normal or reverse phase. The pump has 1% accuracy, which allows for shallow gradients without having to premix the mobile phase. Zero to 5% MeOH in DCM over 20 column volumes is accurate and reproducible.
