When purchasing a precision centrifuge, there are several important factors to consider:
1. **Temperature Control**: Some sensitive samples, such as proteins or cells, can be damaged at high temperatures. Therefore, it's essential to choose a refrigerated centrifuge. These machines maintain a stable temperature range, balancing the heat generated during high-speed operation. For general centrifugation, the sample should typically be kept between 3°C and 8°C. However, the actual temperature depends on the rotor type. For example, a centrifuge with a rated temperature range of -10°C to 60°C might only reach around 3°C with a horizontal rotor, while an angle rotor might only reach about 7°C. It’s crucial to consult with sales representatives or technical staff for precise details before making a purchase.
2. **Rotational Speed**: Centrifuges are categorized based on their maximum speed: low-speed (below 10,000 rpm/min), high-speed (10,000–30,000 rpm/min), and ultrahigh-speed (above 30,000 rpm/min). Each model has a rated maximum speed, which is measured under no-load conditions. The actual speed may vary depending on the rotor type and the sample being processed. For instance, a centrifuge rated at 16,000 rpm/min will rotate at that speed when empty, but the speed must be lower when samples are added. Different rotors also affect the maximum speed—horizontal rotors may reach up to 15,000 rpm/min, while angle rotors might only go up to 14,000 rpm/min. Always confirm these specifications with the manufacturer to ensure compatibility with your needs.
Choosing a centrifuge requires careful consideration of both temperature and speed requirements. It's always recommended to select a model with a maximum speed higher than your target to allow for flexibility and long-term use.
