Laboratory Water

Puretech offers world leading solutions for laboratory water systems

Working with Evoqua, global leaders improving water quality, Puretech offers a range of products to meet laboratory water requirements.

 

The water quality we offer exceeds all relevant standards including ASTM Type I, CLSI and ISO 3696 Type I. It can be used for all typical laboratory applications from AAS, routine analysis up to critical cell and tissue cultures and pyrogen sensitive applications. For industrial customers, we offer systems up to 10 m³/h to fulfil all requirements.

 

Type 1 Ultra Pure Water

Typically, an ultra pure water or high purity laboratory water system has three stages: a pretreatment stage to produce purified water, a primary stage to further purify the water, and a polishing stage.  Evoqua provides the technology in our systems for this final polishing stage.

Our systems fulfil the specifications associated with the production of ultra pure water described by ASTM (American Society for Testing and Materials) D1193, ISO (International Organisation for Standardisation) 3696, and CLSI-CLRW (Clinical and Laboratory Standards Institute-Clinical Laboratory Reagent Water).

Type 1 laboratory water is used for critical laboratory applications including:

  • HPLC
  • GC
  • AA
  • ICP-MS
  • Buffers
  • Culture media for mammalian cell culture
  • IVF
  • Reagents for molecular biology

Credentials

AstraZeneca Research and Development Centre

Puretech engineered and installed a purified water to system at the AstraZeneca Research and Development Centre, Cambridge , taking raw water from the mains through pre-treatment and purification using OASYS units. The purified water, which is stored in a 5000-litre tank, is distributed via a stainless-steel ring main to user points in the laboratories.
