The 7120BR benchtop high-capacity high-speed refrigerated centrifuge is a state-of-the-art instrument designed specifically for modern research and laboratory environments. With its outstanding performance and broad applicability, it has demonstrated exceptional capabilities in various fields, including biochemistry and pharmaceutical R&D. Featuring a high-capacity design, this centrifuge can accommodate up to four 750 mL centrifuge tubes, significantly enhancing experimental efficiency and throughput to meet the demands of high-throughput sample processing. Its high-speed rotation capability, combined with a precise microcomputer control system, ensures an efficient and stable centrifugation process. With a maximum speed of 20,600 rpm and a maximum relative centrifugal force of 30,554×g, it provides researchers with powerful separation and purification capabilities. Additionally, the 7120BR is equipped with an advanced refrigeration system that uses eco-friendly refrigerants to ensure stable and controllable temperatures within the centrifuge chamber. With a wide temperature control range from -20°C to +40°C, it provides an ideal low-temperature environment for processing various sensitive samples. The user-friendly interface, featuring a 7-inch LCD touchscreen, makes setup and monitoring intuitive and convenient, further enhancing the user experience. Furthermore, multiple safety protection mechanisms-such as overspeed, over-temperature, motor overheating, and door interlock-ensure the safety of both the equipment and laboratory personnel. In summary, the 7120BR benchtop high-capacity high-speed refrigerated centrifuge has become an indispensable tool in the fields of research and experimentation due to its outstanding performance, wide range of applications, and high level of safety.
ISO9001:2015 certification; ISO13485:2016 ,CFDA registration and CFDA production qualifications
1. The all-new XIUI 3.0 operating system features microcomputer control and programmable operation, with direct drive via a brushless variable-frequency motor for precise speed control.
2. 7-inch wide-viewing-angle LCD touchscreen with digital input for simple operation; the interface displays settings and operating parameters in real time. The all-steel housing features a corrosion-resistant, textured finish with smooth contours. The industrial human-machine interface design prioritizes visual aesthetics while ensuring safety, resulting in high brand recognition.
3. Equipped with an imported fluorine-free refrigeration compressor unit (refrigerant R404a) that meets environmental standards. It features a pre-cooling function and a wide temperature control range of -20°C to +40°C, enabling rapid attainment of the set temperature. The chamber incorporates standard-compliant copper tubing, providing strong heat exchange capabilities to ensure consistent centrifugation results.
4. Equipped with multiple audible and visual warning protection functions, including overspeed, over-temperature, imbalance, incorrect operation, overcurrent, overvoltage, and anti-pinch protection; hydrogen-, oil-, and acid/alkali-resistant fluorosilicone rubber seals capable of long-term operation between -55°C and +200°C; an aesthetically pleasing, tightly sealed vacuum-formed inner door panel that provides dual protection against aerosol leakage; The centrifuge chamber is constructed from a seamless, corrosion-resistant 304 stainless steel monocoque, paired with a steel liner and a sound-absorbing airflow duct design.
5. The lid features an electronic lock and electric strut, enabling smooth, one-touch automatic opening and closing. In the event of a shutdown or power outage, the lid can be manually opened by connecting to a battery. A patented anti-pinch function prevents accidental finger injuries during hasty operations.
6. Optional Bluetooth and Type-C interfaces enable near-field control via a mobile app, facilitating system upgrades and experimental data downloads.
7. 10-speed acceleration/10-speed deceleration; three-stage damping ensures smooth sample operation without resuspension; stores up to 99 program sets; programmable modes include pulse, timer, differential, density, and gradient centrifugation to meet diverse experimental requirements.
8. Hidden condensate drain feature: Simply squeeze lightly to easily drain condensate, preventing motor failure caused by condensation and extending the centrifuge's service life.
9. Optional rotor auto-recognition function automatically loads and locks rotor parameters; parameters can be modified during operation without stopping the machine, and current settings are automatically saved.
10. A variety of aerospace-grade forged aluminum rotors (angle rotors only) and polyamide fiber adapters are available, compatible with centrifuge tubes or reagent vials ranging from 0.2 mL to 750 mL; capable of centrifuging various MTP microplates, PCR plates, cell culture plates, and deep-well plates.
