witeg can offer a range of volumetric flasks in a manner no other competitor can offer. Next to our standard products, we also manufacture 50 intermediate sizes. This allows us to provide a solution for all measuring ranges.
Each class A volumetric flask bears the „DE-M“ marking in accordance with the German measurement and calibration regulations, valid from January 2015, with the tolerances of DIN EN ISO 1042 and is also marked CC.
We also produce volumetric flasks and other measuring devices according to USP by the tolerances of ASTM E 288 and usually have all products in stock. All measuring devices are delivered with a quality certificate which provides information on the accuracy of the entire production lot.
As the only manufacturer so far, we depict our production lot in a graph display with addition of the standard tolerances in order to compare them with the exact accuracy.
In the future, our volumetric flasks will have the additional unique characteristic C.C. based on “conformity certified” but also with the background of it being particularly accurate.
The user can expect a fully transparent, precise measuring device of highest quality “made in Germany” with an additional certificate of conformity.
Our overall supply of volumetric flasks should currently receive your entire attention. The customer needs to experience our variety and our special quality level which is underlined by the excellent quality certificate.
