- The Efficient Solution for Preparative Separations
- The Prep SFC 660 system, developed by Sepiatec, represents a powerful solution for preparative separations by means of supercritical fluid chromatography (SFC). The unit has been designed for flow rates of up to 660 ml/min at a modifier portion of 40 %.
- In spite of its remarkable capacity, the Prep SFC 660 system features a compact design with measurements of 150 x 68 x 178 cm (W x D x H), so that integration within a walk-in laboratory hood does not create any problem. Additionally, below the unit, several large fraction vessels or a safety cabinet for solvents may be placed.
- The Prep SFC 660 is equipped with three 400 bar high-pressure pumps. A CO2 pump with 400 ml pump head, a modifier pump with 250 ml pump head and a modifier/add-on pump with 150 ml pump head. The total flow – at a modifier portion of 40 % – amounts to 660 ml/min. Up to three different organic modifiers can be mixed and used for separations.
- Besides the column mounting, the injection valve and the UV flow cell are also integrated within the column oven, which is heatable up to 50° Celsius. Separation columns with inner diameters between 25 and 50 mm and a length of up to 800 mm are admissible.
- When working in “Single Mode”, up to 8 fractions can be collected (CO2 flow 180 ml/min)."
- As fractions are collected in unpressurized state, not only safety is increased, but also handling is simplified, and limitations with respect to the size of fraction volumes do not exist. This option proves to be extremely convenient when working with stack injections."
