The Thermo Scientific HFA 15.50 fixed-angle rotor is a Heraeus-design rotor for 8 x 50 mL tubes on the Sorvall Stratos and Heraeus Biofuge Stratos centrifuges. Moreover, this rotor offers a 34 degree angle for balanced pellet formation and supernatant separation. In addition, the HFA 15.50 accommodates high-risk applications with integrated sealed configuration. As a result, you process biohazardous samples safely on the Stratos superspeed platform.
Furthermore, the HFA 15.50 stands out with its 34 degree angle versus steeper alternatives. Therefore, this configuration offers a good balance between pellet quality and supernatant clarity. Moreover, this rotor is specifically designed for 50 mL tubes with variable bottom shapes. Additionally, this rotor accommodates both conical and round-bottom tubes.
In addition, the HFA 15.50 offers tube adapters for smaller formats through separately available parts. Subsequently, you process 50 mL conical tubes, 50 mL round-bottom tubes and smaller formats via adapters. Moreover, this rotor is part of the Heraeus-design portfolio for laboratories with legacy centrifuges. As a result, your investment in Stratos centrifuges remains productive.
Finally, the HFA 15.50 is ideal for microbiological sample processing and protein pelleting in high-risk environments. Therefore, this rotor is the standard choice for laboratories that work with infectious material on the Stratos platform. As a result, you combine sealed biocontainment with reliable superspeed performance.

Heraeus-design fixed-angle rotor for 8 x 50 mL tubes on the Thermo Scientific Sorvall Stratos and Heraeus Biofuge Stratos centrifuges. With a 34 degree angle and sealed configuration, the HFA 15.50 offers a balanced combination of pellet quality and supernatant clarity. Suitable for high-risk applications and microbiological sample processing. O-ring replacement kit available for long-term maintenance.
The HFA 15.50 is compatible with the Sorvall Stratos and Heraeus Biofuge Stratos centrifuges. Moreover, this rotor is specifically designed for the Heraeus Stratos superspeed platform. In addition, this rotor offers 8 x 50 mL capacity for high-risk applications. As a result, you process up to 400 mL of sample per run in a validated superspeed environment.
HFA 15.50 stands for Heraeus Fixed-Angle 15.50. Moreover, the “15” refers to the maximum rotor speed in the 15,000 rpm class. In addition, “50” stands for the capacity of 50 mL per tube. As a result, you recognise the type and specifications directly based on the model name.
The HFA 15.50 has a 34 degree angle, a balance between steeper and shallower alternatives. Moreover, this angle offers a good combination of pellet quality and supernatant clarity. In addition, samples accelerate faster at a moderate angle than at a shallower configuration. As a result, you combine efficient centrifugation with good sample separation.
The HFA 15.50 accommodates standard 8 x 50 mL conical tubes or 50 mL round-bottom tubes. Moreover, tube adapters are sold separately for smaller formats such as 15 mL conical tubes, 30 mL Oak Ridge tubes and 16 mL tubes. In addition, contact Poly Temp for the complete list of available adapters. As a result, you flexibly process different tube formats on the same rotor.
High-risk applications refer to centrifugation of biohazardous or infectious samples. Moreover, the HFA 15.50 offers a sealed configuration for safe processing of this type of material. In addition, the sealed design prevents aerosol release during centrifugation. As a result, you process microbial cultures, viral material and other infectious samples safely.
For the HFA 15.50, an O-ring/gasket replacement kit is available (SKU 75003404). Moreover, this kit extends the lifespan of the sealed configuration. In addition, regular maintenance is recommended for optimal biocontainment performance. As a result, you maintain seal integrity throughout the entire lifespan of the rotor.
