This water is filtered to the highest degree and is suitable for work where the smallest levels of impurities would compromise a result. It is sterile and has a limited shelf life.
Normally used in applications such as:

  • Laboratories
  • Medical Analysis and testing.
  • Culture development
  • Pharmaceuticals
  • High-end electronics

Specification

Sterile and with near zero contaminant content.

Conductivity < 0.056 – 0.06µS
Resistivity 18MΩ/cm
pH 7
Chlorides <0.1 ppm
Sulphates <0.1 ppm
TOC < 500 ppb
Bacteria Sterile

It is important to mention that this water is produced to these standards and is regularly tested on site “unofficially” to ensure parameters are met.

The second it is containerised, resistivity and conductivity can diminish due to the uptake of CO2.

When samples are sent off to our external laboratories, they are unable to certify conductivity and resistivity at the levels we advertise due to the CO2 uptake after containerisation, transport and time taken to test.

However, Micro and salts are accurate.

FAQ

Q: How soon can you deliver?

A: Next working day if ordered before 2 pm. Timed Service £20 and Saturday before noon an additional £50

Q: What is the shelf life of this water?

A: 1-2 weeks if sealed. Use immediately when open. The pH levels will lower when exposed to air.

Q: Will the conductivity be 0.056µS?

A: Close to this value but will raise as CO2 dissolves into it. 0.056µS is achieved at the time of production.
