Onpharma has a proprietary manufacturing technology that allows us to manufacture our Sodium Bicarbonate to a known pH level, making your local anesthetic better and more predictable.
Onset Sodium Bicarbonate Inj., 8.4%, USP Neutralizing Additive Solution cartridges contain 1.7 mL volume and are packaged in a four-cartridge package. Each cartridge can buffer up to 20 injections, approximately 80 injections per 4-pack.
Onset Sodium Bicarbonate Cartridges have a 3-year shelf life. Once removed from the 4-pack tray and placed in the Mixing Pen, the cartridge should be used within 5 days.
