When working with biological samples, maintaining the integrity of your reagents is crucial. ProClin biopreservative plays a vital role in preserving these materials, ensuring your experiments yield reliable results.

ProClin preservatives are widely used in various industries to prevent microbial contamination in products such as in vitro diagnostic (IVD) reagents, pharmaceuticals, and cosmetics. They effectively inhibit the growth of bacteria, yeast, and mold, thereby extending the shelf life and maintaining the integrity of these products.

What is the composition of ProClin 300?

Composition of ProClin 300:

ProClin 300 is a blend of active ingredients designed for broad-spectrum antimicrobial activity. Its primary components include:

5-Chloro-2-methyl-4-isothiazolin-3-one (CMIT)
2-Methyl-4-isothiazolin-3-one (MIT)

These isothiazolinones work synergistically to disrupt microbial cell functions, leading to effective preservation. ProClin 300 contains 3% of these active ingredients in a water-based solution.

Differences Between ProClin 150, 200, 300, and 950:

The ProClin series offers various formulations to cater to different preservation needs:

ProClin 150: Contains 1.5% CMIT/MIT with magnesium salts as stabilizers, suitable for applications requiring lower preservative concentrations.

ProClin 200: Also has 1.5% CMIT/MIT but includes both magnesium and copper salts, offering enhanced stability for certain formulations.

ProClin 300: Features a higher concentration of 3% CMIT/MIT with alkylcarboxylate stabilizers, providing robust antimicrobial activity for a broad range of applications.

ProClin 950: Contains 9.5% MIT without additional stabilizers, effective over a wider pH range (2.0-12.0), making it suitable for formulations with extreme pH conditions.

Conclusion

Selecting the appropriate ProClin preservative depends on factors such as desired antimicrobial strength, formulation pH, and specific application requirements.
