The Only System with Integrated Bagtank Technology

Originally developed for the pharmaceutical industry, our single-use bag integrated as a tank system on the side of Arium® Mini protects intermediately stored pure water reliably from secondary contamination. 

The 5-liter bag, consisting of our specially manufactured proprietary S71 film material, is multilayer and compliant with ISO and USP standards for biocompatibility. With the quality and composition of the Arium® Bag, you can optimally store your pretreated pure water for later production of Type 1 ultrapure water. 

Compared with conventional tanks the disposable Arium® Bag is easy to exchange in less than 5 minutes, enabling you to easily renew your storage tank. This eliminates not only time-intensive cleaning, but also hazardous sanitization. Moreover, the Arium® Bag integrated on the side reliably prevents secondary contamination of your purified water, ensuring constant water quality for the long term.

Convenient Operation for Your Requirements

With intelligent technology, the Arium® Mini ensures continuous protection against secondary contamination and therefore the highest water quality at all times. The closed Bagtank system automatically regulates pressure equalization so that no CO2 can penetrate. This additionally prevents contamination by ionic impurities and maintains consistently low conductivity.  

As an added benefit, you will profit from the especially high cartridge capacity because there is less demand placed on the ion exchangers. Moreover, you can prevent the formation of a permanent biofilm, and therefore eliminate additional TOC loading. Depending on your requirements, you will just need to replace the bag every six months to start off fresh. 

Arium® Mini Essential – The New System for Laboratories Featuring Di Water Taps

The new deionized water system for laboratories.

Your laboratory provides a connection that supplies you with pretreated (RO | DI | EDI) water? Then you best meet your daily requirements for Type 1 ultrapure water with the new Arium® Mini Essential.

This space-saving system will be directly connected to the on-site deionized water line of your lab and thereby manages completely without storage tanks for intermediate storage. The directly supplied DI feed water will be immediately subjected to the ultrapure water purification process.

With this technology, the new Arium® Mini Essential completes our portfolio of systems for Type 1 lab water purification while providing you with all of the innovations and benefits of the Arium® Mini product family:

  • For a Type 1 ultrapure water requirement of 10 liters a day
  • Optional UV lamp, especially for analytical applications
  • Color touch display for intuitive to use direct access to all dispensing options
