Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, and in particular to a worktable for observing cell culture under a microscope. Background Technology

[0002] Cell culture is a technique that artificially simulates the in vivo environment of a living organism in a laboratory to promote cell growth, division, and reproduction. This method allows researchers to culture and observe cell behavior and properties under in vitro conditions. Cell culture has wide applications in medicine, drug development, gene research, vaccine production, and many other fields.

[0003] Currently, the height of existing cell culture workbenches is relatively fixed and cannot be adjusted according to the operator's height. This causes shorter people to bend over, leading to back and waist discomfort after prolonged operation; while taller people need to lower their heads, which also leads to neck fatigue and is not conducive to long-term work.

During this process, the two drive rods move the lifting platform upward, and the limiting post slides upward along the limiting frame to prevent the lifting platform from tilting left or right until the lifting platform rises to the appropriate position. The dual-axis motor is then turned off, and the drive motor is started again. The drive motor causes the gear to rotate, which in turn causes the gear ring to rotate. The gear ring causes the placement slots on the storage tray to pass under the microscope in sequence, making it convenient for the operator to observe the cell culture status in sequence. During this process, the two clamps and sponge pads are fixed by the compression of the springs and telescopic rods, which also reduces the vibration force during the rotation process.
