The components of the GAUDLITZ stool sample preparation device, which is already on sale in several countries, can be manufactured in a variety of colours. If you are thinking of emphasizing the corporate identity of your company in your own individual colours or would like to differentiate tests from one another, then why not ask for the stool sample preparation device in your colours. If you decide to do this, a bright colour should be chosen for the tube's sample rod so that the laboratory worker can easily see the stool sample taken.
