Teledyne Isco - CombiFlash® Rf+
No Documents
RFID method automation, more fractions, larger screen, higher pressure – all in a smaller package.
The TLC to Gradient calculator automatically determines optimal separation parameters while minimizing run time.
There is no need to wait to access data - built in networking allows you to connect to the CombiFlash® Rf+ to monitor and remotely control your experiment, analyze data, and print to network printers.
View UV spectra in real time - during peak elution. Review the spectra to confirm that the system is monitoring the correct wavelength. Interactive screen lets you change parameters instantly during the run if another wavelength would be more appropriate.
Rapid column air purge prevents solvent from being discarded with the used column. It is better for the environment, safer in the lab, and eliminates messy column removal.
Easy scale-up with built-in method-scaling means you won't need to re-develop your method. You save time when you increase reaction size. You can even scale up to a 3 kg column run on a CombiFlash Torrent.
