  • Synergistic preservative systems for chemistry reagents
    Patent number: 5464850
    Abstract: A family of solutions that can be used to calibrate one or more electrochemical sensors has been developed. These systems can be used to determine analytes in biological fluids, such as whole blood, serum, plasma and urine. Since these reagents require preservatives in order to make their shelf life and use life commercially feasible, a system of preservatives which exhibits unexpected synergy in antimicrobial capabilities has been identified. The preferred preservative system includes a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one; 2-methyl-4-isothiazolin-3-one; and 1,3-bis-(hydroxymethyl)-5,5-dimethyl-2,4-imidazolidinedione.
