Sartorius Stedim Biotech presents a new system for laboratories needing low volumes of ultrapure water.
The Arium Mini from Sartorius Stedim Biotech is a compact water system for laboratories needing low volumes of ultrapure water. The system delivers a flow rate of one liter per minute and is suitable for ultrapure water requirements of less than 10L per day. With a width of only 28 cm (11 in.), the unit integrates into nearly any lab environment.
Feed water needed to produce ultrapure water is supplied by the five-liter bag integrated on the side of the system. This bag is optimal for storing purified water. The closed bagtank system prevents secondary contamination while promoting long-term water quality. The bag also facilitates upkeep of the system and reduces maintenance time compared with conventional tank systems, according to the company. The bagtank does not require any hazardous cleaning chemicals, further increasing user safety.
The system is also equipped with a high-resolution, touch-activated color display. User-friendly icons guide the user through the menu. The favorites function automatically stores the volume of ultrapure water last dispensed. This prevents errors during repeated dispensing of identical volumes.
Users can choose between two model versions. The standard version of this system is independent of a permanently installed water tap. Water is supplied to this system via the integrated bag, which is filled by a built-in pump. In the process, pretreated water is pumped into the bag automatically and is used as feed water to produce ultrapure water. In contrast, the plus version can be directly connected to a feed water tap. In this system, feed water is treated first by a pretreatment cartridge, which consists of a combination of activated carbon and a reverse osmosis module, and is stored intermediately in the integrated bag of the system. Final production of ultrapure water then takes place using a scientific purification cartridge developed by the brand.
Additionally, the unit can be ordered in a version equipped with an integrated UV lamp (185/254 nm). This allows for production of ultrapure water that is virtually free of organic components.
