Best Centrifuge Machine For Laboratory
Description
Technical Parameters
In a laboratory environment, the choice of the best centrifuge machine for laboratory depends on a number of factors such as the specific experimental needs, budget, and equipment performance. Selecting the best centrifuge for the laboratory requires comprehensive consideration of many factors such as experimental demand, equipment performance, brand and service. It is recommended to conduct a detailed comparison and evaluation according to the specific experimental needs to choose the centrifuge that is most suitable for your laboratory. At the same time, you can also consult industry experts or technicians for more professional purchase advice.
Laboratory centrifuge is an indispensable equipment in scientific research and experimental operation, and its performance directly affects the accuracy and efficiency of experimental results. When selecting the best centrifuge for the laboratory, we need to consider a number of factors, including experimental needs, equipment performance, brand reputation, after-sales service, and so on.
Acceleration and deceleration curves

 |
When selecting the best centrifuge machine for laboratory, acceleration and deceleration curves are two important performance parameters, which directly affect the running stability and separation effect of the centrifuge. The following is a detailed analysis of the centrifuge acceleration and deceleration curves, as well as the selection method.
Acceleration curve
Definition and function
The acceleration curve describes the law of speed change with time when the centrifuge accelerates from the stationary state to the set speed. A good acceleration curve ensures a smooth start of the centrifuge, reduces impact on the sample, and increases separation efficiency.
Select points
Stationarity: When selecting an acceleration curve, its stationarity should be given priority. The smooth acceleration curve reduces the impact of the centrifuge on the sample during start-up and protects the integrity of the sample.
Acceleration time: The length of acceleration time also affects the performance of the centrifuge. Too long the acceleration time will reduce the experimental efficiency, while too short the acceleration time may increase the impact on the sample. Therefore, it is necessary to select the appropriate acceleration time according to the experimental requirements and sample characteristics.
Adjustable: Some high-end centrifuges provide a variety of acceleration curves for users to choose from to adapt to different experimental needs. When selecting, preference can be given to centrifuges with adjustable acceleration curves.
Examples
Taking a certain model of centrifuge as an example, it provides 9 acceleration curves (numbered 1 to 9), of which curve number 1 provides the slowest acceleration rate, which is suitable for experiments with high sample impact requirements; Curve number 9 provides the fastest acceleration rate for applications where experimental efficiency is sought. Users can choose the appropriate acceleration curve according to the experimental requirements.
Deceleration curve
Definition and function
The deceleration curve describes the law of speed change with time when the centrifuge decelerates from the set speed to the stationary state. A good deceleration curve can ensure that the centrifuge stops smoothly, avoiding the sample in the centrifugal tube to produce violent shaking, affecting the separation effect.
Select points
Smoothness: Similar to acceleration curves, the smoothness of deceleration curves is also an important consideration when selecting. The smooth deceleration curve reduces the impact of the centrifuge on the sample during the stop process and protects the integrity of the sample.
Deceleration time: The length of deceleration time will also affect the performance of the centrifuge. Too long deceleration time will reduce the experimental efficiency, while too short deceleration time may increase the impact on the sample. Therefore, it is necessary to select the appropriate deceleration time according to the experimental requirements and sample characteristics.
Braking system: The braking system of the centrifuge has an important effect on the smoothness of the deceleration curve. Some high-end centrifuges use advanced braking technology to achieve a fast and smooth deceleration process. When choosing, preference can be given to centrifuges with advanced braking systems.
Examples
Also taking a model centrifuge as an example, it provides 10 deceleration curves or braking curves (numbers 0 to 9), where curve number 0 disables the active deceleration function (that is, the centrifuge decelerates naturally by inertia when it stops), curve number 1 provides the slowest active deceleration rate, and curve number 9 provides the fastest active deceleration rate. Users can choose the appropriate deceleration curve according to the experimental requirements.
Comprehensive selection suggestions
When selecting the best centrifuge in the laboratory, in addition to considering the acceleration and deceleration curves, it is also necessary to conduct a comprehensive evaluation in conjunction with other performance parameters. Here are some suggestions for a comprehensive selection:
Clear experimental requirements
Select the appropriate centrifuge model and configuration according to the specific needs of the laboratory.
Focus on brand and reputation
Choose a well-known brand and a good reputation of centrifuge manufacturers to ensure the quality of equipment and after-sales service.
Consider budget and cost performance
Under the premise of meeting the needs of the experiment, choose the centrifuge with the highest cost performance.
Field test and evaluation
If conditions permit, candidate centrifuges can be field tested and evaluated to understand their actual performance and operating experience.
In summary, acceleration and deceleration curves are one of the important performance parameters to consider when selecting the best centrifuge in the laboratory. By choosing the right acceleration and deceleration curves, you can ensure smooth centrifuge operation, improve separation efficiency, and protect sample integrity.
Noise level

When choosing the best centrifuge machine for laboratory, noise level is an important performance parameter that cannot be ignored. Noise not only affects the comfort and work efficiency of the experimental personnel, but also may indirectly affect the accuracy of the experimental results. Here is a detailed analysis of the noise levels of laboratory centrifuges, along with recommendations for choosing a low-noise centrifuge.
The current situation of centrifuge noise level
Centrifuge will produce a certain amount of noise during operation, and its noise level is affected by a variety of factors, including centrifuge model, specification, operating state and use environment. In general, the noise level of centrifuges is between 45 and 70 decibels, but there are some high-end brands of centrifuges that are able to control the noise level in a lower range.
For example, some high-end brands of frozen centrifuges, such as Eppendorf, can control the noise level below 45 decibels by using advanced noise reduction technology and precision manufacturing processes, which is very suitable for noise-sensitive laboratory environments, such as teaching laboratories or quiet scientific research experimental environments. However, not all centrifuges can achieve such a low noise level, some common models or low-end brands of centrifuges, due to technical limitations or manufacturing cost considerations, the noise level may be higher, even more than 60 decibels.
The impact of noise levels on the laboratory
Impact on the comfort of the experimental personnel
Long-term exposure to a high noise environment, the experimental personnel may appear irritability, inattention and other problems, affecting work efficiency and experimental quality.
Impact on experimental results
Although the noise itself will not directly change the experimental results, long-term high noise environment may lead to fatigue and boredom of the experimental personnel, which will affect the accuracy and consistency of the experimental operation.
The impact on the equipment
The high noise environment may also have adverse effects on the centrifuge itself, such as accelerating the aging of the equipment and increasing the failure rate.
The selection of low noise centrifuge recommendations
Before buying a centrifuge, you should know its noise level in detail, and try to choose a model with a low noise level. Information can be obtained by consulting the product manual, consulting the manufacturer, or referring to the reviews of other users.
The noise environment of the laboratory is also one of the factors to consider when choosing a centrifuge. If the laboratory itself is noisy, the requirements for the centrifuge noise level can be appropriately relaxed; However, if the laboratory is more sensitive to noise, you should choose a centrifuge with a lower noise level.
Well-known brands usually have more advanced technology and stricter quality control standards, and their centrifuges tend to perform better in terms of noise control. In addition, well-known brands also provide more perfect after-sales service and technical support, which helps to ensure the normal operation of the equipment.
In addition to the noise level, you also need to pay attention to other performance parameters of the centrifuge, such as speed, centrifugal force, capacity, temperature control, etc. These parameters will directly affect the separation effect and scope of application of centrifuge. In the selection, should be based on the specific needs of the laboratory comprehensive consideration.
If conditions permit, a candidate centrifuge can be field tested before purchase to understand its actual performance and noise levels. Through actual operation and observation, the performance and applicability of the centrifuge can be evaluated more intuitively.
Summary
Noise level is one of the important performance parameters to consider when choosing a best centrifuge machine for laboratory. In order to ensure the comfort and efficiency of the experimental personnel, as well as the accuracy of the experimental results, the centrifuge with low noise level should be selected. In the selection, the noise level of the centrifuge, the noise environment of the laboratory, other performance parameters of the centrifuge and after-sales service should be considered comprehensively to select the centrifuge that is most suitable for the needs of the laboratory. Through reasonable selection and configuration, you can create a quiet, efficient and comfortable laboratory environment.
