The PURELAB Option provides Type II +/II pure water on demand with a wide range of flow-rates to suit your needs. Applications range from glassware washing and the feeding of ultrapure water systems to cell culture and media preparation. The PURELAB Option-R provides additional bacteria and inorganic quality for your more critical applications.

  • Delivers market leading microbial performance. In addition to simple sanitization and composite vent filtration, the PURELAB Option-R system is the only fully recirculating Type II+ pure water system on the market, ensuring high specification water
  • Features "Reverse Osmosis feed optimized" resin mixes to increase the ion exchange capacity of consumables and minimize running costs
  • Quick and easy sanitization and replacement of consumables to reduce maintenance time
  • PURELAB Option systems are designed to be easy to access whether wall or bench mounted with a convenient dispense tap. They can be used with our wrap-around reservoirs to save space whilst optimizing purity

To operate a PURELAB Option-S / R Systems, a tank with 5 level switches is required.
