Many Flow FFF separations require sub-ambient temperatures for sufficient stability and to prevent microorganisms or grow. On the other hand especially polymer separations benefit also from elevated temperatures up to 90°C. Every Flow FFF separation is a function of temperature and stable retention times can only be guaranteed if the channel temperature is not influenced by laboratory temperature fluctuations. Obviously, temperature control will also help to comply with GLP requirements. Remote control is possible via conventional I/O and via the serial RS232 port.
