Lonza's LAL Reagent Water (LRW) is manufactured at theWalkersville, MD, USA facility and is tested to purity requirements beyond thatof Water for Injection (WFI) and most other non-pyrogenic water products. Thepurified water system used to produce the LAL Reagent Water is routinelymonitored and tested to meet all USP requirements for WFI. Lonza LAL ReagentWater is tested to ensure the endotoxin levels are < 0.005 EU/mL, which isfifty times lower than the USP/EP WFI requirement of < 0.250 EU/mL. Additionally,Lonza has a Positive Product Control (PPC) requirement for the LAL ReagentWater of 75-150%, which is more stringent than the 50-200% PPC recovery allowedby the Pharmacopeia. This ensures the absence of any inhibitory or enhancingproperties in the LAL Reagent Water.Use Lonza’s LAL Reagent Water for preparation of any controlor sample when performing the endotoxin detection test. Lonza’s water is testedto be endotoxin free and compatible with your endotoxin assay. LAL ReagentWater is equivalent to Water for Bacterial Endotoxins Test (BET).
