Gaudlitz set itself the goal of incorporating as many customers' needs as possible by having many variations of the stool sample preparation device. Consequently, Gaudlitz has relied on a modular design of the stool sample preparation device. Both the geometry and the size of the device's sample rod can be manufactured in different variations. In order that the sample can be extracted more simply, the sample rod can, for instance, be made with four straight or three oblique grooves. In addition, the length of the sample rod may be individually tailored to meet your particular needs.
