The Thermo Scientific M-20 microplate swing-out rotor is a compact swinging bucket rotor for microplates on the X4 and S4 Series centrifuges. Moreover, this rotor offers optional ClickSeal carriers for biocontainment of biohazardous plates. In addition, the M-20 reaches a maximum speed of 4,000 rpm and an RCF of 2,272 x g. As a result, you process up to 6 microplates per run on a compact and versatile platform.
Furthermore, the M-20 stands out with its choice between standard open carriers and ClickSeal sealed carriers. Therefore, this rotor adapts to both routine and biohazardous plate protocols. Moreover, the 90 degree swing-out design offers uniform sedimentation within the wells. Additionally, this configuration promotes efficient plate handling on the X4 and S4 Series.
In addition, the M-20 accommodates various plate configurations. Subsequently, you process 2 x 3 standard microplates or 2 x 1 deep-well plates per run. Moreover, this rotor is compatible with both the X4 and S4 platforms, unlike many other microplate rotors. As a result, you combine multi-platform flexibility with biocontainment capabilities.
Finally, the optional ClickSeal carriers are ideal for biohazardous plate applications. Therefore, this rotor is the standard choice for laboratories that work with infectious material in microplate format. As a result, you safely process viral samples, microbial cultures and other infectious plate protocols.

Compact microplate swing-out rotor for the Thermo Scientific X4 and S4 Series centrifuges. With a capacity of 2 x 3 standard microplates or 2 x 1 deep-well plates, the M-20 offers multi-platform flexibility. Includes standard open carriers and optional ClickSeal carriers for biocontainment of biohazardous plates. Ideal for ELISA, qPCR and high-throughput screening.








The M-20 is compatible with the Sorvall X4T, X4TR, X4FR, S4T, S4TR and S4FR centrifuges. Moreover, this rotor reaches a maximum speed of 4,000 rpm on all compatible models. In addition, all models share the same RCF of 2,272 x g. As a result, the M-20 delivers consistent performance on both the X4 and S4 platform.
The M-20 accommodates various plate formats via two carrier options. Moreover, you process 2 x 3 standard microplates per run (6 plates total) with open carriers. In addition, this rotor supports 2 x 1 deep-well plates per run. As a result, you combine flexible plate formats on a single rotor.
ClickSeal carriers are optional sealed carriers for the M-20 with integrated biocontainment. Moreover, these carriers prevent aerosol release during centrifugation of biohazardous plates. In addition, you install the ClickSeal carriers in place of the standard open carriers. Therefore, choose ClickSeal carriers when you work with infectious material, viral samples or microbial cultures.
Open carriers offer plate access up to 65 mm height without sealing, whereas ClickSeal carriers support up to 45 mm height with biocontainment. Moreover, open carriers are ideal for routine plate applications. Conversely, ClickSeal carriers offer safe processing of biohazardous samples. Therefore, choose open carriers for maximum plate height and ClickSeal carriers for biocontainment.
The M-20 is the most compact microplate rotor with multi-platform compatibility (X4 and S4). Moreover, the HIGHplate 6000 offers higher capacity (10 plates) and higher RCF (6,168 x g), but only works on the X4 Series. In addition, the Fiberlite H3-LV offers the highest capacity (28 plates) but works on many more centrifuges. Therefore, choose the M-20 for multi-platform plate applications with biocontainment option.
The M-20 is highly suitable for ELISA protocols, qPCR preparation and high-throughput screening. Moreover, this rotor is the standard choice for laboratories that combine multi-platform flexibility with biocontainment capabilities. In addition, this rotor accommodates viral samples, microbial plate cultures and infectious material via ClickSeal carriers. Furthermore, this rotor is suitable for cellular assays and drug discovery.
