Why Precision MSQ™ is the best choice:
Vials made with standard glass contain impurities which can leach into your sample. This can change the pH level of your sample and ultimately alter the accuracy of your results. Precision MSQ Vials are made with the purest materials under the strictest mandates for cleanliness right here in the United States. Less impurities in the glass means less alteration of your sample and far greater accuracy of your results.
