When purchasing a precision centrifuge, there are several important factors to consider:
1. **Temperature Control**: Some sensitive samples, such as proteins and cells, can be damaged by high temperatures. In such cases, it's essential to choose a refrigerated centrifuge. These devices maintain a specific temperature range, balancing the heat generated during high-speed rotation with the cooling system. For general centrifugation, the ideal temperature is typically between 3°C and 8°C. However, the actual temperature may vary depending on the rotor type. For example, a centrifuge with a rated temperature range of -10°C to 60°C might cool a horizontal rotor to around 3°C, while an angle rotor might only reach about 7°C. It’s crucial to consult with sales representatives or technical experts to confirm the exact performance of the model you're considering.
2. **Rotational Speed**: Centrifuges are categorized based on their maximum speed: low-speed (below 10,000 rpm), high-speed (10,000–30,000 rpm), and ultra-high-speed (above 30,000 rpm). Each centrifuge has a rated maximum speed, which is measured under no-load conditions. However, the actual speed may decrease when samples are added, depending on the rotor type and sample weight. For instance, a centrifuge rated at 16,000 rpm may operate below that speed when loaded. Different rotors also affect the maximum speed—horizontal rotors can often reach up to 15,000 rpm, while angle rotors may only go up to 14,000 rpm. Always verify these specifications with the manufacturer to ensure the centrifuge meets your requirements. When selecting a centrifuge, it's advisable to choose one with a maximum speed slightly higher than your target speed to allow for variations and future needs.
