Summary
Product identification
SanRO High Rejection RO Composite Membrane Elements are designed for high performance in USP and other high purity water systems. These elements feature sanitary, full-fit outer-wraps to eliminate "dead flow" areas for maximum bacteria control. SanRO components conform to FDA regulation CFR Title 21.
