Sartorius - Type 1 Lab Water Systems - Arium Mini

Type 1 Ultrapure Water Systems

The arium mini is a newly developed system, which delivers a flow rate of 1 liter per minute and is specially designed for ASTM Type 1 ultrapure water requirements of less than 10 liters per day. This space-saving unit with a width of only 28 centimeters (11 inches) easily integrates into nearly any lab environment.

The arium® mini is exclusively made of high-grade materials and is designed to produce ultrapure water from bottled, pre-treated water. With its intuitive operator guidance, closed bag system and the practical arium® aqua stop, the unit is ideal for a daily consumption of up to 10 liters of ultrapure water.

Moreover, this compact laboratory-grade water purification system stands out by virtue of its superior reliability and user friendliness.

Unique Bagtank Technology
arium® mini is the only ultrapure water system with integrated Bagtank technology. Its design features the 5-liter Bag, originally developed for the pharmaceutical industry, integrated on a side panel. The high-quality Bag provides optimal conditions to store your pretreated pure water for the production of type 1 ultrapure water. 


– Buffer & media preparation
– Histology
– Preparation of reagents, blanks and samples
– ELISA (enzyme-linked immunosorbent assay)
– Photometry etc.
