Abstract: A thermal analysis device comprising a replaceable sensor that can be contacted via a contact element of an electrical contacting means, a heating element and a cooling element. The contact element(s) is thermally connected with the heating element and can be heated essentially independently of the operating state of the cooling element even when no sensor is mounted to the device.

Abstract: The invention relates to a multi-channel peristaltic pump, wherein the housing is constituted by a dimensionally stable support frame (1) and a tube retainer (2) clipped thereto by means of a snap connection. A rotor (3) is provided with three rotatable delivery rolls (33a, 33b, 33c) and is mounted on the support frame (1). The tube retainer (2) is provided with a tube bed body (25) which defines on the inside a tube bed and at the end two legs (2a, 2b). Flexible tube sections (43) are received in the tube bed and can be squeezed by the delivery rolls (33a, 33b, 33c) to peristaltically deliver a medium. The two legs (2a, 2b) are resiliently elastic so that they can be radially clipped into the support frame (1). The tube bed body (25) has a substantially omega-shaped design and is provided with a continuous inlet and outlet area that ensures a peristaltic delivery of the respective medium with only few pulsations.

Abstract: The invention relates to a peristaltic pump in which a case is formed by a dimensionally stable supporting frame (1) and by a tube reception device (2) formed thereon by clipping. A rotor (3) provided with three rotatable transport rollers (33a, 33b, 33c). Said tube reception device (2) is provided with a tube bearing body (25) which forms a bed for the tubes on the internal surface and comprises two legs (2a, 2b) on the ends thereof. The tube flexible sections (43) are compresses by said transport rollers (33a, 33b, 33c) in order to ensure the peristaltic conveyance of a medium. The two legs (2a, 2b) are elastically deformable in a radial direction in order to be elastically adaptable on the supporting frame (1). The bearing body (25) is substentially omega-shaped and provided with uniform input and output areas which ensure a medium continuous low-pulsed peristaltic conveyance.
