The BioPure LSX WFI for pharmaceutical applications combines all the components required to expertly deliver and maintain validated WFI pharmaceutical grade water with significant up-front and operating cost savings for the end user.
The System features a High Recovery Operating Mode that automatically adjusts the system for optimal production flow rate while recovering up to 95% of the feed water. This standard feature can save the user tens of thousands of gallons of water and reduce discharge of waste to drain, making the BIOPURE LSX WFI the logical choice for a pharmaceutical research and manufacturing WFI water system.
