Vreceiver™ boric acid with indicator sealed bags

VELP unique Vreceiver™ is a certified formula composed of Boric Acid powder and a mixture of indicators mentioned by AOAC methods (Bromocresol Green and Methyl red) allowing fast and standardized receiving solution preparation for colorimetric titration.

The receiving solution is prepared in a few minutes facilitating the day by day operations instead of the typical time consuming process using single reagents. The result is a reliable and standardized solution for colorimetric titration.
