Questions

1–3 of 3 Questions  
  1. What is the total iodine concentration of the 624-71 Lugol’s solution?

    1 answer
    1. The concentration of Lugol's Iodine for Microbiology, catalog number 624-71, is not explicitly stated. However, the SDS lists the concentration of both the I2 and KI as between 1 to 5%. It is likely that the product contains a "weak" iodine solution.

  2. Are the compositions of 65042-93 and 1092611000 the same?

    1 answer
    1. The composition of 624-71 and 1092611000 is considered proprietary, and while both are diluted solutions of iodine and potassium iodide, no statement can be made regarding their identical nature. Although both are used for the same purpose, there might be theoretical differences between the two products. It may be possible to substitute one for the other, but no side-by-side comparison studies have been performed to determine if one product can be substituted for the other.
