Combine and add purification technologies to ensure the purified water is optimized for your needs and applications.
The different modules of Arium® let you choose and build the system you need in your laboratory. Implement extra purification steps for sensitive analytical purposes or life science research. Place the system on the bench, save space by placing it under the bench or mounting it on the wall. Combine your system with Bagtanks or remote dispensers (Smart Stations) to increase flexibility and add more points of use across your laboratory.
Arium® water purification systems produce consistently on-demand high-quality laboratory-grade water. Suitable for applications requiring low detection limits, sensitive analysis or other critical or analytical applications.
Sartorius Arium® systems use innovative technologies – including iJust®, Bagtanks and cutting-edge displays - to get an excellent user experience.
The display is easy to use, with or without gloves, with a clear and large screen to make sure the data is always visible.
The iJust® system adjusts the wastewater and product water ratio based on the quality of feed water, making sure to minimize the wastewater portion.
The Sartorius Arium® Bagtank system enables consistent water quality over an extended period, thereby providing for long-term, reproducible results. The Arium® Bag, used together with the Bagtank, is exchangeable, and therefore does not require extensive cleaning procedures with chemicals.
Make sure your system runs perfectly from day one by having Sartorius’ experienced engineers perform the installation. Ask about qualification (IQ/OQ) together with installation to ensure you meet regulatory requirements. Sign service contracts for maintenance as well as preventive maintenance to ensure your Arium® system works as intended and to reduce down-time and malfunctions.
Make sure to find the right water for your application as depending on the applications you might need different quality or purity water. Choosing to low quality might interfere or even ruin your samples or experiments, while choosing to high quality might be unnecessarily expensive. Choosing a water purification system that produces consistently and reliably water where you can monitor the quality at all times gives you ease of mind and usually is less expensive than using bottled water.
In the laboratory, there are several instruments and systems that require feed water for regular operations. Because of impurities, standard tap water is not sufficient and needs to be purified to reduce the possibility of calcification for example.
- Feed ultrapure water systems
- Feed distilled systems
- Water for Laboratory devices (Autoclaves | Washing Machines etc.)
General laboratory and less sensitive and critical applications need consistent pure water with reproducible and reliable quality to ensure that the water does not interfere with the samples or experiments. General laboratory water can also be used for feeding instruments or systems.
- Buffer, media and pH solutions
- ELISA (Enzyme-Linked Immunosorbent Assay)
- AAS (Atomic Absorption Spectroscopy)
- Solutions for chemical analysis and synthesis
- GF-AAS (Graphite Furnace Atomic Absorption Spectrometry)
- Preparation of reagents, blank samples, etc.
Life Science and molecular biology applications need high-purity and quality ultrapure water that has been treated to ensure low levels of RNase/DNase, endotoxins and bacteria to ensure no interference or inhibitions of your samples or experiments.
- Northern Blot
- Southern Blot
- Western Blot
- Endotoxin analysis
- Production of monoclonal antibodies
- PCR (Polymerase Chain Reaction)
- DNA Sequencing
- Nutrient media for cell culture (Mammalia & plant)
The critical and most sensitive analytical applications require ultrapure water with a low level of TOC to ensure the water used for sample preparation or rinsing does not include impurities that might interfere with results (e.g. showing as ghost peaks) or resulting in shorter life time for the columns in your analytical instruments due to clogging.
- SPE (Solid phase extraction)
- Trace metal analysis
- IC (Ion chromatography)
- ICP-MS (Inductively Coupled Plasma Mass Spectrometry)
- GC-MS (Gas Chromatography-Mass Spectrometry)
- HPLC (High-Performance Liquid Chromatography)
- TOC analysis
If you do general, critical or life science analysis in your laboratory, impurities can have an impact on your results. For example, ions in your water can cause interference with reagents, or organic material can create ghost peaks in your chromatography diagrams. To ensure reliable and constant results, it is important to use purified water optimized for your applications.
Standards provide direction on what quality is needed for certain applications or industries. It is important to know if you need to follow a specific standard in your application/industry. Some examples of generally used standards are the American Society for Testing and Materials (ASTM), the International Organization for Standardization (ISO), the Clinical and Laboratory Standards Institute – Clinical Laboratory Reagent Water (CLSI-CLRW) and the International Pharmacopeia (including USP, EP and JP).
Lab-grade water quality and purity varies. The type used depends on laboratory application. Tap water is usually too inconsistent with inorganics, organics, particulates, etc. to be reliable for laboratories or experiments. Laboratory water is categorized according to quality and purity. The most common lab water standard is ASTM, which categorizes the water into Type 1 (ultrapure water), Type 2 (pure, DI or general lab water) and Type 3 (primary or RO water). The different types are suited for different applications and should be used accordingly to ensure good and consistent results in research and production.
There are different types of water varying by quality and purity. Water purity is categorized according to general standards (e.g. ASTM, ISO) from highest to lowest as Type 1 (ultrapure water), Type 2 (pure, DI, or general lab water) and Type 3 (primary or RO water). In the Pharmacopeia, water is categorized as Purified Water and Water for Injection (WFI).
Lab Applications can be divided into three categories in terms of laboratory water: analytic and life science applications, general and feed water. For feed water applications, (such as dish washers, autoclaves or Type 1 water purification systems), you can use Type 3 water. For general applications that are a bit more critical (such as sample, media and buffer preparation) and for less sensitive analytical methods, Type 2 water should be used. Type 2 water can also be used as feed water for autoclaves, washing or feeding Type 1 water systems. For the most critical applications, Type 1 water should be used. For critical life science applications, a Type 1 ultrapure water system - together with an ultrafilter - should be used. If it is analytical work (more sensitive analytical methods such as HPLC, ICP), the ultrapure water system should have an UV-light implemented.
Depending on which water quality is required, various technologies can be used and combined. For Type 3, reverse osmosis (RO) purification is typically used. For Type 2, it can be a combination of RO and ion exchange technology. Type 1 is mainly based on ion exchange on already pretreated water (either Type 3 or 2). These processes can be further optimized with additional components like activated carbon, ultrafiltration, UV-lamps, etc. Add-on steps depend on the applications for which the water is used. Generally, Type 3 or Type 2 water is used for feeding instruments or preparing non-critical solutions, whereas Type 1 water is used for all critical applications, like analytic or life science.
To ensure high water quality and purity - as well as system and consumables quality - regular check-ups are recommended. For this purpose, it is recommended to agree on a service contract with the manufacturer when possible. The system can be maintained by customers to some degree. However, to avoid risk of losing high-quality water or damaging the system - and to reduce downtime and ensure error free operation - it is recommended that maintenance is done by qualified service technicians. Consumables can usually be changed by the customer.
Depending on feed water quality and consumption per day, the intervals to replace consumables may vary. Consumable and system materials will also show sign of fatigue after time and lose their properties. As a result, this might affect the quality of your laboratory water. Therefore, it is recommended to regularly perform maintenance check-ups on the system and change consumables according to recommended intervals to ensure water has a high quality and purity.
For some industries it is important to be able to confirm dispensed water quality, and there are different options when saving quality data. If you need to save water quality data, make sure your system has this capability. Depending on the system, it can either be saved electronically (via USB or SD-card) or printed as a hard copy. Using a printer ensures data cannot be manipulated or falsified.
Every laboratory requires water for sampling, dilution, blanks, buffer preparation and media preparation as well as feed water for different instruments (such as dishwasher or autoclaves). The water is either store-bought or sourced from a water purification system. A purification system in the laboratory means fresh water on-demand. Therefore, there is no risk of storage contamination – you know your water is always of good quality. The amount and type of water needed might determine if a water purification system is required. If your daily water consumption is very low (<5 L/day), it might not be worth it, but it always depends on your specific application and situation. In general, the continuous expenditure of bottled water is a higher total cost over time than the total cost of investing in a purification system.
There are several aspects to consider when buying a water purification system. First, consider the application you need water for, which will determine the type of water you need. You also need to consider how much water is needed per day, and even per hour. Daily consumption can help determine the size of the system you need. In addition, you should also consider your laboratory space - do you want the purification system on the bench, on the wall or under the bench? Do you need one or several additional points-of-use? Your feed water source is also important to consider, as it determines what kind of configuration you need. Cost and budget are also important, not just of the water system, but also the ongoing maintenance and running costs. If monitoring and traceability are important, you may need a system that records quality parameters or usage data.
Using a centralized system means you are feeding water to a whole building. However, with a centralized system it is difficult to control the values and quality of Type 1 water. Therefore, it is recommended to have a Type 1 water purification system at the point-of-use. With a decentralized system, it is possible to qualify the water, giving you control over your lab water’s reliability.
Yes. As each installation is slightly different, our application and service teams will be able to help you plan and accomplish the integration of your water systems into your lab furniture.
Yes, but to minimize the risk of contamination by particles, etc., the system should be separated from the dispense device when possible. The producing unit should be kept in a separate room and connected with a dispensing unit placed in the clean room. The installation should, however, be done with a service technician, as everything needs to be adjusted to local conditions.
With the help of service, you can be sure that your water purification system works as intended from day one! Qualified service engineers are always recommended for the installation to avoid risks of installation errors as well as to save your own engineer’s time. It is usually also possible alongside installation to get the system qualified (IQ|OQ). This will ensure and prove that the system is running according to the system specifications and is compliant with regulatory requirements as well as GMP conformity. Moving forward it is recommended to do regular maintenance as well as preventive maintenance checks to ensure a smooth operation with reliable and reproducible water quality. One way to do this is to sign a service contract, which helps you keep regular checks and, again, saves time as well as minimizes unplanned downtimes.
