Protecting sample integrity during centrifugation is a critical step that directly affects the accuracy and reliability of experimental results. The following are some key measures to provide literature references for the integrity of your samples during centrifugation:
1. Reasonably set centrifugation time and speed
Speed selection:
Choosing the right speed is the key to protecting sample integrity. Too high a speed may cause the sample to be damaged by excessive centrifugal force, such as cell rupture, protein denaturation, etc. Therefore, the appropriate speed range should be selected according to the characteristics of the sample and the experimental requirements. For fragile samples, such as cell suspensions, a lower speed should be selected for centrifugation to reduce mechanical damage. Expert tip: Protect your samples with precision. Careful selection of speed is crucial to prevent sample damage during centrifugation. Consider the characteristics of your samples and experiment requirements before making your decision. Opt for lower speeds when dealing with delicate samples like cell suspensions to minimize mechanical stress.
Centrifugation time：
The length of centrifugation time will also affect the integrity of the sample. Excessive centrifugation time may cause excessive dehydration of the sample or other adverse changes. Optimize your sample’s integrity by carefully controlling the duration of centrifugation. Over-spinning can lead to dehydration and other unwanted alterations to your sample.
The centrifugation time should be reasonably set according to the characteristics of the sample and the separation requirements to ensure that the sample can be fully separated and not damaged during the separation process. Designed with your sample in mind, you can trust that the centrifugation time is precisely adjusted to guarantee optimal separation without any harm to your sample.
2. Use appropriate centrifuge tubes and adapters
Choose matching centrifuge tubes:
The choice of centrifuge tubes should match the model and rotor of the centrifuge to ensure stability and safety during centrifugation. Make sure your centrifuge tubes are compatible with your specific model and rotor for optimal stability and safety during centrifugation.
For fragile samples, such as cell suspensions, good quality centrifuge tubes should be used to reduce the risk of breakage. The right equipment can make all the difference in preserving delicate samples, like cell suspensions. With strong and durable centrifuge tubes, you can minimize the risk of breakage and ensure your results will remain accurate.
Use of adapter:
The adapter fixes the centrifuge tube during centrifugation to prevent it from falling off or breaking during high-speed rotation.
The adapter should be compatible with the centrifuge tube and rotor to improve the stability and safety of centrifugation. Compatible with both centrifuge tubes and rotors, ensuring safe and stable centrifugation.
3. Control centrifugal temperature and humidity
Temperature control:
Some samples are sensitive to temperature, such as proteins, enzymes, etc. During the centrifugation process, the appropriate temperature should be controlled to prevent sample denaturation or inactivation. The correct temperature control is essential in maintaining sample integrity, especially for sensitive components like proteins and enzymes. Don’t risk denaturation or inactivation during centrifugation – take control of the temperature for reliable results.
For centrifugation experiments that require a specific temperature, a centrifuge with temperature control function should be selected, and the appropriate temperature should be set according to the experimental requirements. Centrifugation experiments require precise temperature control for accurate results. With the centrifuge’s built-in temperature control function, you can easily choose the exact temperature needed for your specific experiment. Stay in control of your experiments and achieve the best results every time.
Humidity Control:
In some cases, humidity changes during centrifugation may also have an impact on the sample. Therefore, when possible, the humidity in the centrifuge chamber should be controlled to maintain sample stability. To ensure the best possible results, it is recommended to control the humidity within the centrifuge chamber during centrifugation. This will help to maintain sample stability and avoid any potential impact on the sample due to changes in humidity. As industry experts, we understand the importance of accuracy and consistency in your samples, which is why controlling the humidity is a critical factor in obtaining reliable results.
4. Avoid sudden braking and vibration
Smooth start and stop:
During the centrifugation process, sudden braking and sudden acceleration should be avoided to reduce the impact and vibration on the sample. Selecting a centrifuge with multi-speed acceleration/deceleration function can achieve smooth start and stop of the centrifugation process to protect the integrity of the sample. A centrifuge with multi-speed acceleration/deceleration function allows for smooth start and stop of the centrifugation process, minimizing impact and vibration on the sample and preserving its integrity.
Reduce external vibrations:
Place the centrifuge on a stable, sturdy surface to reduce the impact of external vibrations on the centrifugation process.
5. Other considerations
Sample pretreatment:
Before centrifugation, the sample should be properly pretreated, such as dilution, filtration, etc., to improve the centrifugation effect and protect the integrity of the sample.
Regular maintenance and calibration:
Maintain and calibrate the centrifuge regularly to ensure that it is in good working condition. This helps reduce the impact of mechanical failures and errors on sample integrity. Regular maintenance and proper calibration are crucial to the optimal functioning of the centrifuge. By adhering to these steps, you can minimize the risk of mechanical issues or mistakes that may negatively affect the integrity of your samples.
Protecting sample integrity requires comprehensive consideration of multiple factors during the centrifugation process, including the setting of centrifugation time and speed, the selection of centrifuge tubes and adapters, the control of centrifugal temperature and humidity, and avoiding sudden braking and vibration. By taking these measures, the integrity and stability of the sample can be ensured during the centrifugation process. By taking into account various factors, such as setting the right centrifugation time and speed, selecting the appropriate centrifuge tubes and adapters, controlling the temperature and humidity during centrifugation, and preventing sudden braking and vibrations, sample integrity is guaranteed throughout the process.
