The introduction of automatic biochemistry instrument selection

The less non-interfering elements that can be measured by the biochemistry analyzer when analyzing the content of chemical elements, the better, and the need to wash the test article with ultrapure water for more effective calibration. The water purifier for biochemical analysis is an ultrapure water preparation instrument designed specifically for fully automatic biochemical analyzers. Biochemical analysis water purifier according to the biochemical instrument needs ultrapure water consumption characteristics, generally designed for 10L / hour to 60 liters per hour.

Biochemical analytical water purifier for ultrapure water requirements generally require ultrapure water resistivity & gt; 10 MΩ-cm.

Biochemical analytical ultrapure water purifier is designed with certain characteristics:

* Water storage tanks using closed non-pressure water tanks, automatic biochemical analyzers can be directly sucked into the machine

* Equipped with a large tanks, 120-500 liters of volume. 500 liters.

* Equipped with reverse osmosis membranes, purification packages are larger than ordinary ultrapure water specifications.

* Biochemical analytical ultrapure water purifiers are often designed to conserve consumables due to the rapid replacement of consumables associated with high water production.

* Biochemical analyzers are more commonly used in hospital testing departments, and the working hours of the medical sector are somewhat unique, requiring easy and quick replacement of consumables and timely after-sales service for biochemical analyzers. These requirements make the biochemical analyzer type ultrapure water machine in the user maintenance and consumables replacement easier.

* Bioanalytical ultrapure water dispensers are usually floor standing, increasing the space inside the dispenser to fill more consumables and reducing the frequency of consumable replacement.

Biochemical analyzer water purifier is not managed as a medical device:

In order to meet the needs of supervision and management of medical devices, the State Food and Drug Administration issued a circular on February 7, 2007, to clarify the definition of the classification of the extracorporeal shockwave cardiovascular therapy system and other 68 products.
