Niutec AG has validated and accredited analytical methods for determining extractables and leachables. These analytical methods make it possible to cover a broad spectrum of substance classes.<\/p>\n

During the manufacture of medical devices, various processing aids are used, some with imprecise composition specifications. Substances can remain on the surface of the products or even permeate them. Furthermore, a wide range of materials is used, which are chosen to suit the application of the medical device. Every material has a risk of releasing possible components due to its composition. Therefore, it must be ensured for each medical device that no residues of processing aids or no material components are dissolved or released in a toxicologically relevant quantity.<\/p>\n

In order to be able to cover as many potential extractables and leachables as possible, the medical products have to be extracted into different solvents and the extract solution has to be analyzed further. The extraction parameters and solvent selection strongly depend on the application and composition of the medical device. Niutec AG has extensive knowledge in this area.<\/p>\n

Our experts will be happy to develop a test strategy tailored to your product.[\/vc_column_text][vc_empty_space height=”40px”][\/vc_column_inner][\/vc_row_inner][\/vc_column][vc_column width=”1\/4″][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1581513658950{background-color: #ededed !important;}”][vc_column width=”1\/4″][\/vc_column][vc_column width=”1\/2″][gt3_spacing height=”25px”][vc_column_text]\n
