The Thermo Scientific TX-400 swing-out rotor is the most versatile swinging bucket rotor for the Multifuge X1 Pro and Megafuge ST1 Plus centrifuges. Moreover, this rotor offers a maximum capacity of 4 x 400 mL. In addition, the TX-400 reaches a speed of 5,000 rpm and an RCF of 4,696 x g. As a result, you process large volumes in compact benchtop centrifuges.
Furthermore, the TX-400 supports sixteen different adapter configurations. Therefore, you process virtually any tube, bottle or microtube format in one rotor. Moreover, this rotor offers adapters for 400 mL bio-bottles, 250 mL Nalgene bottles and 200 mL conical bottles. Additionally, the TX-400 accommodates up to 136 microtubes of 1.5/2 mL or 76 blood tubes of 5/7 mL per run.
In addition, the TX-400 offers optional ClickSeal biocontainment lids for safe processing of biohazardous samples. Subsequently, this rotor is highly suitable for clinical, pharmaceutical and biotech laboratories. Moreover, the biocontainment certification meets the standards of TÜV NORD CERT. As a result, you process blood products, cell cultures and conical tubes safely.
Finally, you switch the TX-400 in just three seconds thanks to Thermo Scientific Auto-Lock rotor exchange. Therefore, no tools are required for a rotor change. As a result, you switch quickly between applications such as blood processing, cell culture, urine analysis or bio-bottle centrifugation.
