Because the tubes are held at an angle, the distance a particle must travel to hit the wall (the sedimentation path) is shorter than in a swinging-bucket rotor. This significantly reduces run times. High k-Factors: Rotors like the feature low k-factors (e.g., ), which indicates high pelleting efficiency.
: Choose your rotor based on your volume and speed requirements. The is frequently used for larger volumes at approximately , while the is preferred for maximum speed in smaller volumes.
TLA rotors are a gold standard for pelleting EVs from serum or plasma samples. For instance, the Go to product viewer dialog for this item. is often used at speeds of for 2 hours to extract miRNAs from EVs. Hugel Tla

relative to the axis of rotation). This configuration is particularly effective for pelleting applications where speed and efficiency are critical. Because the tubes are held at an angle,
Researchers use these rotors to study virus disassembly and genome release, such as with Herpes Simplex Virus (HSV-1).
Fixed-angle rotors are designed to hold tubes at a specific angle (usually between 20∘20 raised to the composed with power 45∘45 raised to the composed with power : Choose your rotor based on your volume
Regularly inspect the O-rings and rotor cavity for signs of wear or corrosion to ensure vacuum integrity during high-speed runs.
