A rheometer or viscometer has a first measuring part and a second measuring part, between which a sample space for receiving a material sample is formed. By means of a drive device, at least the second measuring part can be rotated and/or can be oscillated, it being possible for the drive movement of the drive device to be transferred to the second measuring device via a transmission element. The drive device is arranged on the side of the first measuring part that is facing away from the second measuring part and the transmission element penetrates through the first measuring part, particularly at a through-bore.
