Environmental Analysis Ready to use Water Chemistry Reagents and Standards
Precision stabilised reagents and standards were developed in 2003. These ready to use reagents were the first commercial reagents to be used in discrete water chemistry analysers in the world that provided stability for twelve months.
The ideal solution to environment analysis
- Off the shelf convenience
- Shelf-life stability minimum of 12 months
- Automated reading of the bar code label for reagent identification and on-board stability delivers speed and efficiency
Innovation of precision reagents
Precision® stabilised reagents and standards were developed in 2003. These ready to use reagents were the first commercial reagents to be used in discrete water chemistry analysers in the world that provided stability for twelve months.
Serosep pioneered the introduction of fully automated Water Chemistry Discrete Analysers in Ireland in 1999. As many laboratories began to avail of the new automation they still were burdened with the tedious task of manufacturing, quality control and testing of their in house water chemistry reagents.
In 2003 Serosep launched precision range of water chemistry reagents and standards. The new range of ready to use, quality controlled and tested reagents offered Environmental Laboratories improved efficiency and convenience.
The use of Precision® Reagents and Standards will allow for increased productivity and efficiency increasing quality and confidence. This is cost effective method complying with GLP regulations.
