Ultrapure Lab Water Systems
Overview of Ultrapure Lab Water Systems
Marlo’s Pre-Engineered Laboratory Water Systems are designed to serve as the centralized, purified water source for a variety of academic, medical, and other research laboratory facilities. Designed to meet or exceed the Type II reagentgrade water platform set forth by CAP/NCCLS and ASTM standards. Standard systems are furnished with all the treatment equipment fully pre-piped, pre-wired, and factory-tested on a common skid package to minimize field installation and start-up costs. The standard system includes the following equipment:
- Power Generation
