Today, Xiaobian introduces some good methods for using high and low temperature test chambers, so that your test chamber can save energy, extend its life, and guarantee the test results. (1) All sides are empty. High and low temperature test chambers should be placed in a well ventilated area and kept away from heat and direct sunlight. When placing the high and low temperature test chambers, the left and right sides and the back should have appropriate space, generally 70 cm or more, to facilitate heat dissipation. (2) Dissatisfaction. When placing the test sample in the high and low temperature test chamber, it is necessary to leave a certain interval, and there should be a gap between the wall and the wall to facilitate air circulation. (3) Reduce the opening of the door. During the test, the number and time of opening the high and low temperature test chambers should be minimized. The test temperature can be restored because it takes more than a few minutes to open the test chamber door compressor. Friends who are interested in high and low temperature test chambers can also send some of your experience to our website, share it with everyone, and let more people exchange and learn.
The circulatory system is a continuous system of closed ducts in all parts of the body, including the cardiovascular system and the lymphatic system.Blood circulates in the cardiovascular system.Lymphatic fluid flows through the lymphatic system.The lymphatic system can also be thought of as an auxiliary part of the venous system because it flows centripetally along a series of lymphatic ducts and eventually drains into the veins.
This model is suitable to medical institutions to explain human anatonv, such as thoracic surgery and internal medicine curriculum as visual aids, can be used for classroom health demonstrations and anatomy teaching aids and can also be used for children's educational toys.
