How is the product supplied ?   - As a 2-part mix, in packs containing 12 kits (enough to make 12 x 2 litres of EPA 1002/1003 medium).   Each part of the 2-part mix is sterile and is provided in a convenient 5ml syringe; the two syringes are provided in a sealed sterile pack.

To Make the Medium:    - Open a 2-syringe kit.  Then add the the contents of one 5ml syringe to 2 litres of pure water, mix thoroughly, then add contents of the other 5 ml syringe and mix (instructions accompany the product).  Aerate the mixture, adjust pH if necessary (recommended for EPA method 1003.0) and filter sterilise.

NOTE: EPA-1002/1003 is sterile; the final sterilisation step (described above) is necessary only if diluent (water) is not sterile and/or if sterile technique has not been used while preparing the final medium.
