It's indispensable for biosafety experiments.

　　What’s the difference between a biosafety centrifuge and a conventional centrifuge?

　　Biosafety is an important component of national security. Generally, it refers to the hazards or potential risks—whether human-induced or non-human-induced—that biological factors pose to a nation’s society, economy, public health, and ecological environment, as well as the strategic and comprehensive measures taken to prevent and manage these hazards or risks. A biosafety laboratory is a biological laboratory that, through protective barriers and management measures, can effectively avoid or control the hazards posed by harmful biological agents being handled, thereby meeting biosafety requirements. Such laboratories are primarily used for research in fields including microbiology, biomedicine, biochemistry, animal laboratories, and biopharmaceuticals. According to different levels of protection, biosafety laboratories are classified into four levels—from Level 1 to Level 4; among these, higher-level biosafety laboratories include those with Biosafety Levels 3 and 4.

　　Biosafety laboratories serve as the infrastructure and crucial platform for conducting biosafety-related research. High-level biosafety laboratories refer to those with biosafety containment levels of Tier 3 and Tier 4, typically used for research on highly pathogenic infectious diseases.

　　Biosafety centrifuges play a crucial role in laboratory settings. During the centrifugation process, these centrifuges are equipped with a three-stage filtration system, including an ultra-fine 3-μm biological-grade filter that ensures the air within the centrifuge chamber remains clean. In standby mode, the biosafety centrifuge employs a dual-cycle sterilization system featuring both dual-tube ultraviolet irradiation and high-density plasma, effectively eliminating any bacteria that might survive inside the chamber. The simultaneous internal and external clean-air circulation modes operate independently without interfering with each other, thereby maintaining a biochemically safe laboratory environment and completely addressing the risks posed to operators by aerosols.

　　The rotor features excellent airtightness, effectively preventing the leakage of aerosolized pathogenic microorganisms from the rotor or adapter. The safety cover is easy to open, and the adapter is simple to operate. By opening the biosafety cover in a negative-pressure environment within the safety cabinet, this design effectively protects the operator’s safety and saves time during sample extraction.

　　If you’re considering purchasing a biosafety centrifuge in the near future, you can take this model as a reference:

　　1·The TGL-21M is a multi-purpose, high-speed, high-capacity refrigerated centrifuge—a smart centrifuge featuring internationally advanced technology—and can be equipped with biosafety rotors.

　　2. Microcomputer control, high-definition large-screen LCD display, intuitive controls for simplified operation, user-friendly touchscreen interface, providing detailed information on various operating parameters and ideal performance processing status—simple and easy to use.

　　3. Equipped with automatic rotor identification function and featuring an integral sealing ring made of food-grade silicone rubber, compliant with GMP certification. The centrifuge has obtained FDA certification from the United States.

　　4. Equipped with 10 acceleration and deceleration programs that enable easy and quick conversion and setting between rpm and RCF, and simultaneously display graphical curves of both acceleration and deceleration, ensuring ideal centrifugation results.

　　5. Equipped with multiple protection features including overspeed, imbalance, overtemperature, and door-lock protection, ensuring the instrument’s safety and reliability.

　　6. A novel electrically controlled door lock that allows for easy closing and secure locking of the centrifuge.

　　7. A large-capacity centrifuge chamber, space-saving design, and a wide variety of rotor specifications enable multi-purpose functionality in a single unit.

　　8. Equipped with a pre-cooling function featuring direct buttons, and utilizing an imported high-performance compressor unit with fluorine-free refrigerant, making it more environmentally friendly and energy-efficient.

　　The above is a brief introduction to biosafety centrifuges. This article takes the 1·TGL-21M biosafety centrifuge manufactured by Shanghai Luxiangyi Centrifuge Instrument Co., Ltd. as an example and provides a simple analysis. We hope this information will be helpful in your purchasing decision!
