  • Calibrated specific activity
  • Sterile glass ampoules, pH~10 
  • Free of toxic substances 
  • Special volumes and specific activities on request


    The ampoules contain an aqueous solution of NaH14CO3, 2.4 mM in sterile water, and are ready to use in measurements of phytoplankton primary production. The NaH14CO3 is purified in the DHI Laboratories by distillation in order to remove metals that can affect the primary production. The sterile ampoules are distributed with a certificate specifying the radioactivity.
