Abstract

A cryostat microtome (100, 500) comprises a cryostat chamber (104), a sample holder (106) arranged inside the cryostat chamber (104) and having an object head (108, 400) configured to hold a sample (102), a sectioning unit (110) arranged inside the cryostat chamber (104) and configured to section the sample (102), and a cooling system (114) having a first circuit (116) for cooling the cryostat chamber (104) and a second circuit (200) connecting the first circuit (116) with the object head (108, 400) for cooling the object head (108, 400). The first circuit (116) comprises at least 20 g and at most 100, 500 g of a working fluid having a GWP100, 500 of less than one, a compressor (120) arranged outside the cryostat chamber (104) and configured to compress the working fluid, and at least one evaporator (128, 134) arranged inside the cryostat chamber (104) and configured to cool the cryostat chamber (104) by evaporating the working fluid. The second circuit (200) comprises a heat transfer fluid and a pump (138) configured to move the heat transfer fluid through the second circuit (118, 200).
