titrants
Titrant or volumetric solution is a solution of a reagent with a specific concentration, which is prepared by weighing very pure raw materials in accordance with international guidelines such as USP, ACS, ASTM. In the process of preparing a volumetric solution, it is necessary to perform quality control procedures (QC Control) to accurately determine their molarity using standard reference materials (CRM).
On the one hand, the reference material being so expensive, and on the other hand, the need to repeat the quality control tests several times has turned the preparation and production of these solutions into a costly and time-consuming process. Titrants are not affordable in laboratories. Therefore, Drm has produced a variety of these solutions with a very high degree of precision and supplies them to its customers in suitable containers.
The most important features of Drm volumetric solutions :
- With a certificate of analysis and specified uncertainty.
- Determination of normality for 1 normal solutions up to 1.000 normal range.
- Determination of normality for the range of 0.1 normal to the range of 1.000 normal.
- Shelf life 2 and 3 years.
- Traceable to .NIST.
- The possibility of making volumetric solutions with the normality requested by the customer.
Note: Titrazole is used instead of titrant in the Iranian market, which is an incorrect term. Titrazole is a registered trademark belonging to Merck Company, which is used for titrants manufactured by this company and is not a scientific name.
