摘要： Disclosed is a gripping appliance (1) comprising a base member (11), a plunger actuator (31) and a plunger (30). The gripping appliance further comprises a head assembly (20) releasably attached to the base member (11) and extending distal from the base member (11). The plunger actuator (31) is arranged and configured to move the plunger (30) along a proximal-distal axis (2) of the gripping appliance. The head assembly (20) comprises a carrier (21) and a number of at least two gripping legs (24) The carrier has a through opening configured and arranged to receive the plunger (30) therethrough. The gripping legs (24) each comprise a fixation portion (201), a tip portion (204) distal of the fixation portion, an actuation portion (203) adjacent to and proximal of the tip portion, and a flex portion (202) defined between the actuation portion (203) and the fixation portion (201), wherein the actuation portions (203) of the gripping legs are configured to be in contact with the plunger (30) at least when the plunger is in an extended, distal position. The fixation portions (201) of the gripping legs are rigidly mounted to the carrier (21) of the head assembly (20). The actuation portions (203) and the tip portions (204) of the gripping legs are arranged distal from the carrier (21) of the head assembly and the gripping legs are arranged such that, when no force is transferred from the plunger to the gripping legs, the tip portions (204) of the gripping legs converge in a proximal-distal direction of the gripping appliance.

摘要： A differential scanning calorimeter comprises a temperature-controlled heat source and a sensor arrangement (9). The sensor arrangement (9) comprises sample- and reference-side pan support regions (4r), sample- and reference-side measurement regions, one or more measurement region sensors operative to output a differential heat flow signal (U) representative of the difference between heat flowing across the sample- and reference- side measurement regions (5r) and a sample- and reference-side local heater arrangement (3r). A sample pan and a reference pan are arranged on the respective sample and reference-side pan support region. A volume surrounding the pans is filled with a measuring gas. The method to determine a second calibration factor C E of a differential scanning calorimeter comprises the steps of creating a first steady state situation of a desired temperature. Once the first steady state is reached, applying heating power to one of the pan support region (S) by the use of the respective local heater arrangement and determining the second calibration factor based on the ratio of the differential heat flow signal U and the differential heating power.

摘要： A sensing unit for a differential scanning calorimeter is configured to comprise a superposition of layers of a thermoelectric arrangement 9, 10, a layer of an electrical heater arrangement 21 and a layer of an absolute temperature measurement arrangement 27. The thermoelectric arrangements, the electrical heater arrangements and the absolut temperature measurement arrangements are symmetrically arranged on a sample-side and a reference-side of the sensor.
