Overview:
Handheld centrifuge To distinguish our centrifuge from ordinary ones, we need to take a multi-faceted approach. Simply put, the unique triple-waterproof switch design of our pocket-sized centrifuge provides you with triple-level safety assurance. The innovative motor mount design makes rotor changes effortless, convenient, safe, and quick. The sturdy rubber base, featuring a metallic-colored coating technology, ensures that the instrument remains stable and doesn't shift during operation. Specifically designed by molecular biologists, this pocket-sized centrifuge from our manufacturer is small enough to be held comfortably in your palm, allowing you to perform centrifugation right at your fingertips.
2. Equipped with a built-in thermostat, the handheld centrifuge from the manufacturer features an automatic power-off function that activates when the motor temperature rises excessively during prolonged operation, thereby protecting the motor’s service life.
3. The portable centrifuge manufactured by the portable centrifuge manufacturer can be used as a dedicated isotope centrifuge to reduce the likelihood of contamination in portable centrifuges.
4. The transparent arched top cover allows you to promptly observe the centrifugation process.
When the centrifuge rotates in the forward direction, its effect is to make the intracellular streamlines tend to move closer toward the boundary. This contributes to flow stability, thereby reducing temperature fluctuations. When the centrifuge rotates in the reverse direction, its effect is to squeeze the vortices toward the center, which intensifies the vorticity and makes the flow more unstable, leading to increased temperature fluctuations. During crystal growth, the relationship between the impurity concentration in the crystal and the impurity concentration in the melt is significant. The effective segregation coefficient is effective when the number is small, and becomes less effective as the number increases. The flow state of the melt within the crucible is such that, when the number is small, the flow is relatively stable; when the number is large, the flow becomes more turbulent.
The equilibrium partition coefficient is a constant; the crystal growth rate is influenced by the diffusion coefficient of impurities in the melt. The parameter β represents the thickness of the boundary layer. Temperature variations in the melt near the solid-liquid interface directly affect the crystal growth rate, thereby influencing the value of the Soret effect and, consequently, the impurity concentration within the crystal. Clearly, intense temperature fluctuations can lead to an uneven distribution of impurities in the crystal, resulting in impurity streaks. Therefore, when a centrifuge rotates in the forward direction during crystal growth, the quality of the crystal is improved. Conversely, when the centrifuge rotates in the reverse direction, it has an adverse effect on crystal growth. The results of this experiment provide us with an important insight: in a centrifuge environment, crystal growth is influenced not only by the effects of hypergravity but also by mechanical forces. When performing horizontal directional solidification to grow single crystals in a centrifuge, if the centrifuge’s rotation direction aligns with the direction of thermal convection within the melt—that is, if the high-temperature end of the melt faces the airflow—the temperature fluctuations in the melt can be effectively suppressed, which is conducive to growing single crystals free of impurity streaks. On the other hand, if the centrifuge rotates in the opposite direction—meaning the low-temperature end of the melt faces the airflow—strong temperature fluctuations will occur within the melt, which is detrimental to the uniform growth of single crystals.
Handheld centrifuge Also known as microcentrifuges or mini-centrifuges, these devices differ from conventional centrifuges in that they are compact in size and lightweight, making them easy to carry. However, there are still performance differences between handheld centrifuges and laboratory benchtop centrifuges. To ensure more accurate experimental results, extend the lifespan of the instrument, and guarantee the safety of personnel, we’ve summarized the following key points that require attention:
1. The voltage of the external power supply system must be compatible. Since centrifuges often operate in outdoor environments, extra attention should be paid to voltage issues, and a good grounding wire is required.
2. The centrifuge should always be kept in a horizontal position, because microcentrifuges are small and lightweight. When not operating in a horizontal position, they tend to shake easily, which can prevent them from functioning properly or even lead to accidents.
3. Regularly inspect and maintain the performance of the handheld centrifuge, as most miniature centrifuges operate outdoors and are prone to vibration during transportation, which can affect instrument accuracy.
4. The samples must be balanced, and when using centrifuge tubes for centrifugation, the centrifuge tubes and the samples themselves must be balanced simultaneously. Centrifuge tubes used in these small-scale centrifuges are extremely small—meaning that the machine can tolerate only very slight imbalances, far less than what larger centrifuges can handle. Therefore, it is crucial for these centrifuges to achieve precise balancing.
5. If any abnormal phenomena are detected during the centrifugation process, immediately turn off the power and notify the manufacturer for inspection and repair.
Handheld centrifuge Characteristics:
1. Temperature-guided design ensures that high-speed operation won't generate excessive heat that could affect the sample.
2. Streamlined design, elegant and stylish; takes up minimal space yet can simultaneously separate 12 × 0.5 ml samples at a time.
3. High-quality composite materials and modern production processes; smooth operation; ensures safety.
4. When the centrifuge lid is opened, the rotor immediately stops rotating, thereby preventing injuries that could occur due to rotation.
5. Utilizes the world’s most advanced wide-band power supply technology (85V-220V) to ensure operational quality.
6. The handheld centrifuge comes with multiple interchangeable rotor heads, allowing it to serve multiple purposes and offering flexible operating parameters.
7. The rubber base prevents the machine from shifting during operation.
8. The centrifuge can be used by individuals in the laboratory, placed on a lab bench, or operated in low-temperature cold environments.
