Abstract

The invention relates to a device for automatically fixing and controlling temperature of in vitro tissues in batches. The device is characterized by comprising a raw liquid storage box body (1) and atissue fixing table (2), wherein a water storage chamber (15), a formaldehyde storage chamber (16) and a raw liquid mixing chamber (17) are arranged inside the raw liquid storage box body (1), and awater injection hole (11) is formed in the water storage chamber (15); a formaldehyde injection hole (12) is formed in the formaldehyde storage chamber (16), and the water storage chamber (15) is connected with the raw liquid mixing chamber (17) through a water adding pipeline (13); the formaldehyde injection hole (12) is connected with the raw liquid mixing chamber (17) by a formaldehyde adding pipeline (14). The liquid distribution is automated and intelligent, the liquid replacement is simple and easy to operate, and is combined with the temperature control, and only the required parametersare selected on a display screen, which greatly reduces the burden on an experimenter. The tissues are fixed in batches, flow sensors are attached to 20 branches of a mixed liquid outlet, and meanwhile, a drainage gun is simple to operate.

Description

technical field [0001] The invention mainly relates to the field of isolated tissue experimental equipment, in particular to a device for automatically fixing and controlling the temperature of isolated tissues in batches. Background technique [0002] Pretreatment of isolated tissues is of great significance in various experiments, and good sample fixation and preservation have a great impact on subsequent biochemical analysis. At present, when fixing a sample, the experimenter needs to manually mix a certain concentration of fixative, and sometimes even need to change the fixative regularly. Manual proportioning and replacement of fixative not only increase the workload of the experimenter, but also the difference in solution concentration caused by manual proportioning will also lead to deviations in experimental results and affect the reliability of subsequent experimental results. If the automatic ratio can be realized, the workload of the experimenter can be significa...
