Handle of slicing table in cell biology laboratory: design and application

In the study of cell biology, microscope technology is one of the indispensable tools, and the premise of microscopic observation is to properly handle and prepare the sample, which includes cutting and fixing the sample. In this process, the slicing table in the cell biology laboratory plays the role ofPlay a vital role. As an integral part of the slicing table, the design of the handle also directly affects the experience of the experimental operators and the quality of the final results.

First, the role and importance of the handle

1. Improvement of experimental efficiency: Good handle design helps to improve the work efficiency of operators. For example, when slicing continuously, if the handle can be quickly rotated conveniently, the experimental time can be significantly shortened; In addition, the proper handle shape can also reduce the fatigue of hands and make the operation smoother.

2. Sample quality assurance: The correct hand-held method can ensure that the sample is pushed into the slicer evenly and smoothly, so as to obtain a higher quality sliced sample. This is of great significance for subsequent analysis.

3. Safety protection: The reasonably arranged handle is not only convenient to hold, but also can prevent accidents to some extent, such as blade injury.

Second, the ergonomic design principle of the handle

Ergonomic design of handles should be based on satisfying the structural characteristics of human body, and pay attention to comfort and safety;

1. Appropriate shape and size: the size of the handle should be suitable for the palm of most people, usually oval or cylindrical, with a diameter of about 24cm. This can not only effectively support the palm, but also not bring oppression to the fingers.

2. The surface material has a good touch: it is generally made of non-conductive materials such as plastic and rubber, which is both light and non-slip; In addition, it is necessary to have certain friction to enhance the grasping stability.

3. The structure is stable and reliable: the connecting part needs to be strong enough to prevent falling off and damage; At the same time, we should also consider whether it is easy to disassemble and clean.

Third, case study-Leica RM 2265 rotary microtome

Leica RM 2265 is a high-end product widely used in the field of pathological diagnosis, which includes a carefully designed handle assembly:

1. Equipped with two handles with adjustable height and angle, which are suitable for users with different heights;

2. With LED indicator function, it is convenient to work at night or in low light environment;

3. Different length specifications (short/long) can be changed according to requirements to meet the operation requirements of specific occasions.

In a word, by paying attention to and optimizing the details, Leica RM 2265 has successfully achieved efficient and stable performance, and thus won the recognition and support of many researchers.

IV. Conclusion

To sum up, although the handle is an insignificant small part, it is directly related to the convenience and reliability of the whole system. With the continuous improvement of scientific and technological level and the increasingly diversified development of users' needs, more innovative improvement measures will appear in the products on the market in the future, further promoting the field of cell biology!
