CombiFlash Torrent

The 8890 GC System features built-in intelligence that enables remote connectivity

Designed for the purification of large quantities of substances

A flow rate of up to 1 litre per minute allows fast purification of up to 300 g sample per separation at a back pressure of up to 100 psi (6.89 bar). The system can be flexibly configured to optimally perform a variety of tasks. 

System description

Different variants of sample application and fractionation are available. In addition, the system offers the advantages of all CombiFlash systems. These are above all the simple operation and high reliability.

The torrent system uses RediSep Rf cartridges with RFID technology. All information is automatically read out, so that a fast, error-free method development is guaranteed. Large scale RediSep Rf columns with different column materials and precolumns with Luer Lock connections are available.
