We now make 2 ranges of GGA standards:
 
1. The single strength, 6.0ml vial, designed for single use
2. The double strength, 9.5ml per vial- enough for 3 standards! (BEST BUY!)
 
**Both products have a 2 year shelf life**

Manufacturing Process

We produce these using DI water, then adding glucose and glutamic acid.  Once the solution is placed within the vial, the material is sterilized at 121C for 15minutes.
 
Once cooled, the resulting product is tested for TOC and COD and the theoretical BOD5 calculated. In addition, heterotrophic plate count is done to ensure sterility and stable shelf life.
 
The vials are then packaged in 50 or 150 count boxes and ready for distribution.
