About High Purity Laboratory Water

There are four levels of water purity recognised in the water purification industry, each of which are used for specific applications in laboratories. The quality of water is defined through a series of measurements of conductivity (µS/cm) or resistivity MΩ-cm), Total Organic Carbon (TOC) in parts per billion (ppb), and bacterial count (CFU/ml).

Here we explain the four types of water used in laboratories, as well as the processes and properties of each type.

1.Ultrapure Water (Type 1)

With a resistivity of 18.2 MΩ-cm at 25°C, ultrapure (Type 1) water is a requirement for analytical laboratories. Flow cytometry, pyrogen sensitive applications, and cell and tissue culture are all typical applications for Type 1 water.

Water with this type of resistivity can still contain organic contaminants, endotoxins and nucleases which don’t impact on resistivity values, so other technologies are required to eliminate them.

Equipment that produces Type 1 water is often referred to as a “polisher” and can be fed from a localised reverse osmosis system, or a centralised ring main depending on usage rate.

Bacteria and organic levels are reduced to the required level, through a dual wavelength ultraviolet (UV) light (185nm and 254nm). The water flows through a vessel containing a UV light, and as it passes through, the light, destroying any genetic organic matter, associated for reproductive functions. This damage prevents the microorganism from multiplying or replicating, which means no infection can occur.

An Ultrafilter (UF) typically rated at 0.01 microns, can also be employed to produce DNase/RNase free water. By using size exclusion, ultrafiltration removes particles and macromolecules including bacteria and viruses.  This technology is employed at the end of the system, to ensure the near-total removal of macromolecular impurities.

Each type of water must go through various processes and technologies to achieve a certain standard of purity. The level of purity then reflects what can be used in laboratories. For that reason, it’s important to be able to distinguish between the four types of water, so you can understand how they are utilised in laboratories.

2.General Laboratory Grade Water (Type 2)

Also known as general laboratory grade water, Type 2 water is produced through a combination of reverse osmosis, and additional technology such as ion exchange or electro deionisation  (EDI). Electro deionisation (EDI)is an electrically driven water treatment technology that uses electricity, ion exchange membranes and resin to remove ionised species from water.

Deionisation removes ions (cations and anions) from RO water by using ion selective resins. Chemical reactions occur as the water passes through the ion exchange beads, resulting in the removal of ions. This process is continued until all unwanted ions are replaced by hydrogen and hydroxyl ions, which form pure water once combined.

Electro deionisation (EDI) is a continuous, chemical-free process of removing ionized and ionizable species from feedwater using DC power. EDI is typically used to polish reverse osmosis permeate and is an alternative to Ion Exchange Technology. Using electro deionisation eliminates the need to store and handle the hazardous chemicals used for resin regeneration in mixed beds.

Reverse Osmosis and Ion Exchange Technology create Type 2 water, which has a resistivity of 1-15MΩ-cm, making it suitable for general applications such as buffer and media production, spectrophotometry and general chemistry.

3.Primary Grade Water (Type 3)

Primary grade pure water (Type 3) uses carbon filtration, cartridge filtration and RO technology and is the most cost-effective way to reduce water contaminants for this application.

Removing up to 99.5% of feed water contaminants, reverse osmosis membranes rated at nominally 0.0001 microns purify water by virtue of rejection.  Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure.

RO technology applies diffusion as opposed to separation, rejecting particles with a higher molecular weight. Feed water temperature, pressure, and the physical condition of the RO membrane are all parameters that affect rejection rates. Rejection rates depend on a number of factors including feed water quality, water temperature and pressure.  For this reason, RO water can’t be specifically classified.

RO water is most commonly used at the starting point for many applications in laboratories, including feeding glassware washing machines and autoclaves. It can also be used as a pre-treatment for ultrapure water systems, or anything that’s considered non-critical.

4.Feed Water

Feed water is also referred to as raw or potable water, and the quality of it is dependent on its source. It is important to obtain a detailed water analysis before deciding on an appropriate system for your facility. Any contaminants present in the feed water can substantially inhibit the performance of the RO membrane and result in fouling and reduced service life. Below are some examples:

Hard Water:  Will require a water softener to remove hardness.

Presence of colloidal clay particles: Will require media filtration and also ultra filtration as a pretreatment.

Presence of iron and manganese: Will require water softener or catalytic media filtration.

Low feed pressure: Will require a booster pump to ensure sufficient pressure for the RO system. Each filtration step will result in a pressure drop; hence a reasonable feed pressure is required to begin with.  Some laboratory units do come with internal booster pumps that mitigate this concern.  The data sheet of the particular RO membrane used, will provide data such as optimum supply pressure to maximise ion rejection.
