The operate in a vertical orientation, making it uniquely set up for the analysis of sintering, studies in Rate Controlled Sintering (RCS) mode and the determination of dilatometric parameters of samples otherwise difficult to be analyzed on classic dilatometers with horizontal design. Unlike in horizontal dilatometry the vertical design does not require the sample to be supported. The specimen stands free on the bottom plate and the push rod is loaded on its tip. The vertical configuration is particularly well suited for sintering studies as well as for all those samples difficult to be tested with horizontal push rod dilatometers. As, for instance, powder samples and samples developing vitreous phases during the test.
