Centrifuges are high-speed machines and essential tools for daily experiments, making their quality paramount. Choosing a reliable, reputable brand not only ensures convenience during use but also reduces losses and hassles caused by future malfunctions. For example, the centrifuge casing should have double or multiple layers of robust steel protective sleeves to prevent potential accidental injuries. However, this danger is often overlooked, and to reduce costs, non-steel or other materials that do not meet safety requirements are still used for the casing. Therefore, we should pay attention to this when purchasing. These unseen details are crucial for safety, and price and quality are directly proportional.
Other safety features of electric centrifuges, such as automatic rotor identification (preventing the set centrifugation speed from exceeding the limit) and locking-cap operation (the centrifuge can only be started after the cap is locked and can only be opened after stopping), are important facilities for protecting the safety of laboratory personnel. Some centrifuges can even monitor the entire centrifugation process, even for imbalances caused by test tube breakage or sample spillage, or whether the rotor cap is properly closed. Different countries have different standard certification programs; good products can pass various stringent certifications, and the more certifications a product has, the more reliable it is. After-sales service from the manufacturer is also a major factor to consider. Centrifuge maintenance is highly technical, and installation and maintenance should be handled by professional maintenance personnel approved by the manufacturer. Therefore, when choosing a centrifuge, safety measures must be considered, and a reliable brand and sales unit should be selected.
When using an electric centrifuge, it's important to note that if a problem occurs during centrifugation, a centrifuge with a locking lid may become stuck, preventing the removal of valuable samples. Repair personnel often cannot arrive promptly. Therefore, centrifuges should have a manual lid-opening port for emergency use. Always ask the engineer how to use it during installation. This way, you'll have a chance to salvage your valuable samples in case of an emergency.
