Laboratory water purification systems
Labman is official distributor for Neptec GmbH lab water systems. Our products are 100% German made high quality instruments with affordable pricing.
Laboratory water systems are devises that purify water to the required water quality for different laboratory applications. Labman offers a wide range of laboratory water purification systems for ASTM type 3 reverse osmosis water, type 2 pure water, type 1 ultrapure water, CLRW water and demineralised water (demiwater).
What is the difference between ultrapure, pure and reverse osmosis?
These water types differ in their purity and their applications.
Ultrapure water (also called type 1 or reagent grade water) is the purest water. Ultrapure water is typically used for critical applications like HPLC, ICP, MS, AA, molecular biology and mammalian cell culture.
Pure water (also called type 2, analytical grade, DI or EDI water) is used for standard applications like buffers, pH solutions, bacterial cell culture and clinical analyzers. Pure water can also be used for a lot of the same applications as reverse osmosis water.
Reverse osmosis water (also called type 3, laboratory grade, or RO water) is used for general applications like glassware rinsing, laboratory dishwashers, autoclaves and water baths.
What lab water system do I need for my application?
To chose the best system for your lab water needs, there are a few considerations:
- What applications need laboratory water?
- What water quality is needed for each of the applications?
- How much of each lab water type is needed each day/week/month?
- What is the feed water quality? (Tap water, reverse osmosis water, DI water, EDI water,…)
- How much water is needed per hour, per day or week?
- What are the ambient conditions? Does the lab water system need to be benchtop, wall-mounted, undercounter or free standing?
- Are there any regulatory requirements for the installation? (For example IQ OQ)
With this info, Labman can support you in finding the best solution for your lab water needs.
Can lab water systems be connected to existing lab equipment or automation platforms?
Lab water systems like reverse osmosis or DI water systems produce water that is stored in a pure water tank. Sometimes direct connection to an instrument like a laboratory dishwasher, autoclave (steam sterilizer) or a climatic chamber is required. These instruments need a certain feed water pressure to work optimally. Booster pumps can be connected to the pure water tank to pressurize pure water to the required feed water pressure for the lab equipment.
Labman offers variable frequency booster pumps suitable for the use in laboratories. Also discover our all-in-one undercounter Proteus systems including integrated 80L pure water tank and booster pump.
What is better: DI water or EDI water?
Lab DI water systems use a deionization cartridge on top of the pre-filtration and reverse osmosis step. The deionization cartridge is filled with single use mixed bed resin to further demineralize the water after the reverse osmosis step. Mixed bed resin (a mix of anion exchange resin and cation exchange resin) has the advantage of being a relatively simple and cheap technology. The resin gets saturated, which means the cartridge is typically replaced every year.
Sometimes DI water also refers to ion exchangers, which use mixed bed resin without prefiltration or reverse osmosis. Ion exchangers are a very different technology.
Lab EDI water systems use an electro deionization module to demineralize the water after the reverse osmosis step. Electro deionization uses mixed bed resin in combination with semi permeable membranes and electrodes. The main advantage of EDI vs. DI is that it is a continuous system (self regenerating), which means there is no consumable cost. The disadvantage is that EDI is an expensive technology. EDI is also sensitive to scaling, which means that in most cases softened feed water is required.
In general DI water systems are more interesting for laboratories with lower lab water consumption and EDI water systems are more interesting for laboratories with a high lab water consumption.

Ultrapure water systems
Ultrapure water systems produce ASTM type 1 water with a resistivity of 18.2 MΩ.cm, TOC < 10 ppb and bacterial count <10 CFU/ml. Ultrapure water is typically used for applications which require very low contamination levels like HPLC, cell culture and mass spectrometry. When starting from tap water, the first production steps also involve reverse osmosis. That’s why systems producing ultrapure water from tap water are in most cases combo systems (see products above). When the feed water for the instrument is already purified (ASTM type 3 reverse osmosis, ASTM type 2 pure or distillated water), a device with a shortened production process can be used (often called polishers). Ultrapure water is typically produced on-demand, so is never stored in a tank.

Reverse osmosis systems
ASTM type 3 reverse osmosis water is often used for general lab applications like glassware rinsing, laboratory dishwashers, autoclaves/ steam sterilizers, climate chambers, water baths, … Often reverse osmosis water is also used to feed ultrapure water systems / polishers. The production unit stores the reverse osmosis water in a suitable tank for intermediate storage. Often when a direct connection with pressurized reverse osmosis is required (for example for laboratory dishwasher, autoclaves,…) a booster pump is required.

Central water systems
Central water systems are the preferred solution when larger volumes are needed, or when the device needs to feed a central loop in a building. Central systems are constructed of industrial grade components, which allow 24/7 production without any issue. Central systems can be configured as ASTM type 3 reverse osmosis systems or as type 2 pure water systems (by electro deionization/EDI).

Ion Exchangers
Ion Exchangers use cartridges of mixed bed ion exchange resin to demineralize water (demiwater). They are an economical alternative to reverse osmosis or pure water when ion removal as a sole parameter is sufficient.
