Sodium bicarbonate [¹⁴C]

• Dilute solutions of NaH¹⁴CO₃ ready to use 
• Different ampoules in stock, e.g., 4, 10, 20, 40 and 100 µCi/ml
• 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 for use in measurements of phytoplankton primary production. The NaH¹⁴CO₃ is purified in the DHI Laboratories by distillation in order to remove metals that may affect primary production. The sterile ampoules are supplied with a certificate specifying the radioactivity.

Minimum order quantity: 10 ampoules for 100 µCi/ml; all other types require a minimum of 50 ampoules.

Please note that shipping radioactivity is relatively expensive.
