Abstract
An object of the present claimed invention is to improve cell cooling performance, keep a temperature of a dispersion medium constant, and improve measurement accuracy. The particle size distribution measuring device of this invention comprises a cell holding body 31 that holds a cell 2 housing a measurement sample and that is rotated by a motor 322, a case (C) having a housing space (S) for rotatably housing the cell holding body 31, and a cooling mechanism 8 for cooling the cell 2. The cooling mechanism 8 comprises a cooler 81, and a supply channel 82 that supplies a gas that has been cooled by the cooler 81 to the housing space (S).
Claims8
A centrifugal sedimentation type particle size distribution measuring device comprising
- a cell holding body that holds a cell in which a measurement sample and a dispersion medium are housed and that is rotated by a rotating mechanism,
- a case that has a housing space in which the cell holding body is housed in a rotatable manner,
- a cooling heat exchanger for cooling the cell, and
- a supply channel that supplies a gas cooled by the cooling heat exchanger to the housing space,
- wherein one end of the supply channel is connected to an inside of the housing space and the other end of the supply channel is connected to an outside of the housing space in a radial direction, and
- the cooled gas is supplied to the housing space from the one end of the supply channel, and the gas in the housing space circulates through the supply channel.
