The Arium® Mini Plus has a touch-activated color display designed with the user in mind. This display functions seamlessly with laboratory gloves, saving time and facilitating daily laboratory work. The display indicates the last volume of water dispensed, the purified water quality and the water temperature. It is possible to control water dispensing manually or in 50 mL increments to add flexibility.


5 Liter Bag For Minimum Maintenance

The bag can be easily exchanged to keep your laboratory running. No chemicals are required to clean the bag, lowering the risk of impurities in future tests. The quick-connect coupling feature is practical and leak-tight, which preserves the closed system.


High-Quality Standards

The Arium® Mini Plus connects directly to tap water, and there are various purification mechanisms to consistently deliver quality water for your lab. The pretreatment cartridge uses high-quality carbon for effective absorption. Impurities are retained by reverse osmosis. Arium® Sterile Plus point-of-use filter reliably removes bacteria to <0.001 CFU/mL using a 0.22 μm membrane, while the Arium® Cell Plus point-of-use ultrafilter efficiently removes endotoxins, RNase, DNase, microorganisms and particles.


Continuous Contamination Protection

Arium® Bagtank technology ensures continuous protection against secondary contamination by using a closed system. The closed system automatically regulates pressure so no CO2 can penetrate. This allows for the maintenance of low conductivity and prevents biofilm formation. Depending on specific laboratory requirements, the bag will need replacing every six months.
