Furthermore, the sealing strip 23 is integrally formed with the sealing bottom edge 22, and the sealing strip 23 is sealed with the card groove 111 to ensure that the heat-insulating partition 2 has a good sealing effect in the inner cavity of the dewaxing cylinder 1; the front end or rear end of the dewaxing cylinder 1 is provided with a drain port 13 connected to the inner cavity, and the drain port 13 is provided with a drain valve.
[0022] The utility model can select the position of the slot 11 in the dewaxing cylinder 1 to be inserted into the heat insulating partition 2 according to the number of samples required for each sample, so as to form a plurality of dewaxing chambers 12 of suitable sizes and independent of each other, so as to avoid cross infection between different samples, and the heat insulating partition 2 can effectively block the heat transfer of the dewaxing liquid in the adjacent dewaxing chambers 12, so as to ensure that the dewaxing temperatures of different samples do not affect each other, and the accuracy of the results is high; the sample slides are inserted into the slot 11 in the dewaxing chamber 12 to prevent the adjacent sample slides from sticking to each other and affecting the dewaxing effect, the sealing strip 23 on the heat insulating plate 21 is sealed with the card slot 111, and at the same time cooperates with the sealing bottom edge 22 at the bottom of the heat insulating plate 21 to ensure a good sealing effect of the dewaxing chamber 12, and the heat insulating partition 2 is detachably arranged in the slot 11, so as to adjust the size of the dewaxing chamber 12, and effectively reduce the waste of dewaxing liquid; in addition, after the dewaxing operation of the sample is completed, the heat insulating partition 2 is removed, and the drain valve is opened to facilitate the discharge of waste liquid.
