PURELAB® Option systems provide an economical alternative to using bottled distilled water and is a more efficient choice compared to a larger distribution system. 
 
PURELAB® Option-S combines pretreatment, reverse osmosis, and ionic/organic removal to deliver better than single distilled quality water from a potable water source. It is offered in 4 models/flow rates and delivers up to 10 megohm purity water. 
 
PURELAB® Option-R features the technologies of the S series unit with the added benefit of an integral recirculation feature. Option R is ideally suited for standard lab techniques and as pretreatment to ultrapure water polishing systems where TOC is a concern.
