Water for Lab Equipment
In the laboratory, there are several instruments and systems that require 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. Solutions for various reagent-grade water types can be selected based on the system requirements.
- Inlet water for ultrapure water systems
- Inlet water for distilled systems
- Water for Laboratory devices
- Text Box(Autoclaves | Washing Machines | Water Baths etc.)
Basic Laboratory Applications
General laboratory and less sensitive and critical applications need consistent pure water (often referred to as type II and III water) with reproducible and reliable quality to ensure that the water does not interfere with the samples or experiments. In general, this pure water can also be used for feeding instruments or systems.
- Spectroscopy Techniques: UV-Vis Spectroscopy, Fluorescence Spectroscopy, Photometry, Atomic Absorption Spectroscopy (AAS), Fourier Transform Infrared Spectroscopy (FTIR)
- Immunoassay Techniques: Enzyme-Linked Immunosorbent Assay (ELISA)
- Sample Preparation Techniques: Buffer, media, and pH solutions, Solutions for chemical analysis and synthesis, Preparation of reagents, blank samples, etc., Cleaning of Laboratory Glassware
- General Laboratory Techniques: Microbiological Media, Chemical Reactions and Synthesis
Molecular Biology | Life Science Applications
Life science and molecular biology applications need ultrapure water without interfering substances like RNase/DNase, endotoxins, and bacteria. This guarantees that your samples and experiments won't be impacted. The water must be treated to remove these substances. This ensures that your samples and experiments are not affected.
- Molecular Biology Techniques: Electrophoresis, Blotting Techniques, PCR Techniques, NGS Techniques, DNA Sequencing
- Cell Biology and Biochemical Techniques: Endotoxin & RNase and DNase Analysis, Immunocytochemistry, Production of Monoclonal Antibodies, Nutrient Media for Cell Culture (Mammalian & Plant), CRISPR-CAS9 Techniques, Chromatography
Analytical Application
Highly sensitive analytical applications require very pure water with low levels of total organic carbon (TOC). This ensures that the water used for preparing samples or rinsing is free from impurities that could impact the results. Impurities may lead to ghost peaks or clogging of columns or instruments, leading to shorter lifespan.
- Chromatography Techniques: (Ultra) High-Performance Liquid Chromatography ((U)HPLC), Ion Chromatography (IC), Liquid Chromatography (LC)
- Mass Spectrometry Techniques: Liquid Chromatography-Mass Spectrometry (LCMS), Inductively Coupled Plasma Mass Spectrometry (ICPMS), Gas Chromatography-Mass Spectrometry (GCMS)
- Sample Preparation Techniques: Solid Phase Extraction (SPE)
- Trace Analysis Techniques: Trace Metal Analysis, TOC Analysis, PFAS Analysis
Arium® Lab Water Systems Feature:
Sartorius’ Arium® lab water purification systems offer a wide range of options to meet your laboratory water needs regarding purity (ultrapure and | or types of pure water), daily consumption and flexibility. Combine and add purification technologies to ensure the purified water is optimized for your needs and applications.
The various Arium® models allow you to select and customize the system that fits your laboratory needs. Implement extra purification steps for sensitive analytical purposes or life science research that require lower organic compound and | or DNase and RNase content. Place the system on the bench, save space by placing it under the bench or mounting it on the wall. Combine your Arium® pure water system with Arium® Bagtanks according to your daily consumption. Additional dispensing units (Arium® Smart Stations) can be connected to increase flexibility and offer more points of use across your laboratory.
Arium® water purification systems consistently deliver high-quality reagent-grade water. They are ideal for applications requiring low detection limits, sensitive analyses, or other critical and analytical tasks.

Frequently Asked Questions
The right system depends on your required water quality. ASTM Type 1 ultrapure water is ideal for sensitive applications like cell culture, PCR, and sequencing in life science labs. For applied research and analytical methods like HPLC or ICP-MS, consistent ASTM Type 1 water ensures accurate, interference-free results. Purified water supports general lab tasks such as buffer preparation and glassware rinsing. Sartorius offers systems tailored to each purity level and application. If you need any support, please do not hesitate to contact us.
Arium® systems use advanced purification technologies like reverse osmosis, ion-exchange resin, UV oxidation, and ultrafiltration to remove impurities, including ions, bacteria, and organics. Integrated monitoring ensures ASTM, ISO, and CLSI-compliant performance.
Pure water is suitable for less critical tasks, while ultrapure water is essential for high-sensitivity analyses like HPLC, PCR, and ICP-MS. Sartorius systems produce both types to meet diverse lab requirements.
Yes, many Arium® systems are designed for direct connection to potable tap water. They include pre-filtration and purification stages to ensure reliable performance from variable feed water sources.
Ultrafiltration removes endotoxins and nucleases (DNase/RNase)—critical for applications involving RNA, DNA, or mammalian cells. Sartorius systems with ultrafilters ensure high purity for these sensitive workflows.
Replacement frequency depends on usage, feed water quality, and system configuration. Integrated alerts and user-friendly design make maintenance easy and predictable to minimize downtime.
