An important role in molecular biology laboratory-centrifuge handle

Introduction:

In the field of molecular biology, centrifugation is one of the most important experimental methods, which plays a key role in cell separation and protein purification. As one of the essential equipment in the laboratory, the centrifuge not only needs excellent performance and stability, but also needs to be equipped with ergonomic operating components. Today we will focus on the centrifuge handle, which is an important part of the centrifuge.

I. Function and classification of centrifuges

Centrifuge is an instrument that puts the sample in a rotating barrel for high-speed rotation to produce strong centrifugal force to separate or concentrate components with different densities. According to different application requirements, centrifuges can be divided into many types, such as desktop centrifuges and frozen centrifuges. No matter what kind of centrifuge, the safety and convenience of its operation are very important.

Second, the design principle of centrifuge handle

1. Safety: Because centrifuges usually run at high speed, it is very important for the safety of operators. In order to prevent accidents, the centrifuge handle should have anti-skid function and be easy to grasp.

2. Convenience: Considering that the operator may frequently open and close the cover during use, the handle of the centrifuge should be designed to be light, flexible and easy to operate.

3. Durability: As a high-frequency precision instrument, the handle of the centrifuge must also have good durability, be able to withstand long-term pressure and keep in good condition.

3. Ergonomic design of centrifuge handle

The design of centrifuge handle should follow the principle of ergonomics to ensure that users can hold it comfortably and apply force easily. This includes but is not limited to the following:

1. The shape of the handle: it is designed to be streamlined, which is convenient for people to wrap the handle with their palms and reduce the pressure on their wrists.

2. Selection of handle material: Use soft rubber or silica gel material to increase friction coefficient and avoid hand slipping.

3. Position of the handle: Make sure that the handle is at an appropriate height, neither too low nor too high, so that users can easily grasp the handle without bending over or stretching their arms.

4. Locking mechanism: A locking device should be designed to ensure more safety and stability when opening or closing.

Four, centrifuge handle application case analysis

Let's look at a practical example: Eppendorf Centrifuge 5810 R is a desktop centrifuge widely used in the field of molecular biology. This model is equipped with an ergonomically designed handle, which makes it easy for users to control even if they wear gloves. In addition, Eppendorf also provides two different types of handles for this centrifuge, one for standard centrifuge tubes and the other for microplates.

Summary:

To sum up, although the handle of centrifuge is small, its function cannot be ignored. Only through reasonable design can we ensure that users can complete various tasks quickly and accurately and effectively protect themselves from harm. With the development and progress of science and technology and more and more attention paid to humanized care, I believe there will be more excellent products in the future to further improve our quality of work and life!
