Nexera UC Prep Benchtop system that can be installed anywhere

Semi Preparative Supercritical Fluid Chromatography System Usually a chiller is required to cool the solvent delivery pump when pumping CO2 at high ow rates. However, the Nexera UC Prep
features a compressor-type cooling unit, reducing the size of the system and allowing it to be installed anywhere. Its footprint is
equivalent to an analysis-scale SFC system.
The Nexera UC Prep is a new preparative supercritical uid chromatography system that offers both the high
performance achieved in the analytical Nexera UC model and additional state-of-the-art preparative SFC
technologies. Coolant line Pump

Stacked injection function eliminates waiting time

Normal injection wastes time between peak elutions. Using the Nexera UC Prep’s stacked injection function, samples can be
injected continuously without any waiting time, enabling more samples to be processed. Settings for this function can be
speci ed easily in the dedicated software.

In preparative SFC, one factor that results in lower recovery rates is increased dispersion of the eluant when the Stacked injection (9 consecutive injections)

the LotusStream separator, successfully reduces sample dispersion and carryover, while also achieving high (1) (2) (3) (4) (5) (6) (7) (8) (9)

for volatile compounds such as the fragrance linalool.
