The Thermo Scientific MT-12 microtube swing-out rotor is a unique swinging bucket rotor for 1.5/2 mL microtubes on the C Series compact centrifuges. Moreover, this rotor offers individual swinging buckets per microtube. In addition, the MT-12 reaches a maximum speed of 13,000 rpm and an RCF of 16,438 x g. As a result, this rotor delivers the highest RCF in the C Series swing-out segment.
Furthermore, the MT-12 stands out with its unique swing-out design for microtubes. Therefore, pellets form centrally at the bottom of the tube. Moreover, this configuration prevents the lateral pellet formation that is typical for fixed-angle microtube rotors. Additionally, centralised pellet formation enables more efficient supernatant removal after centrifugation.
In addition, the MT-12 supports both 1.5 mL and 2 mL microtubes plus filtration columns. Subsequently, you process small-volume research applications where pellet quality is crucial. Moreover, this rotor is ideal for molecular biology protocols such as DNA and RNA isolation. Furthermore, this rotor accommodates spin columns for nucleic acid purification.
Finally, the MT-12 offers an optional ClickSeal biocontainment lid for safe processing of biohazardous samples. Therefore, this rotor is suitable for laboratories that work with infectious genetic material or viral RNA. As a result, you combine high RCF, swing-out pellet quality and biocontainment in a single compact rotor.

Unique microtube swing-out rotor for Thermo Scientific C Series compact centrifuges. With a capacity of 12 x 1.5/2 mL microtubes and 16,438 x g RCF, the MT-12 offers individual swinging buckets for centralised pellet formation. Ideal for DNA and RNA isolation, spin column protocols and small-volume research. Equipped with an optional ClickSeal biocontainment lid for biohazardous samples.








The MT-12 is compatible with Thermo Scientific C1T, C1TR and C1FR C Series compact centrifuges. Moreover, this rotor reaches a maximum speed of 13,000 rpm on all compatible models. In addition, all models share the same RCF of 16,438 x g. As a result, the MT-12 delivers consistent performance across the entire compact 4L benchtop platform.
The MT-12 features a unique swing-out design where microtubes tilt to 90° during rotation. Therefore, pellets form centrally at the bottom of the tube. Conversely, pellets form along the side wall of the tube in fixed-angle rotors. Moreover, centralised pellet formation is advantageous for supernatant removal and visual pellet assessment. As a result, the MT-12 is ideal for applications where pellet quality is crucial.
The MT-12 is ideal for small-volume research applications with 1.5/2 mL microtubes. Moreover, this rotor is highly suitable for DNA and RNA isolation via spin column protocols. In addition, the MT-12 accommodates filtration columns and protein precipitation reactions. Additionally, this rotor is suitable for PCR sample preparation and routine molecular biology.
By default, the MT-12 does not offer biocontainment protection. Therefore, Thermo Scientific offers the optional ClickSeal biocontainment lid (SKU 70902041) for safe processing of biohazardous samples. Moreover, this lid seals the entire rotor during centrifugation. As a result, aerosols remain contained within the rotor and you process infectious material safely.
Yes, the MT-12 is specifically designed for both microtubes and filtration columns. Moreover, this rotor offers maximum tube dimensions of 11 x 50 mm. In addition, standard spin columns for nucleic acid purification fit directly into the individual swinging buckets. As a result, you combine microtube centrifugation and filter protocols in a single rotor.
For the MT-12, two essential replacement parts are available. Moreover, the replacement ClickSeal biocontainment lid (SKU 75005730) is available for maintenance of the biocontainment function. In addition, Thermo Scientific offers replacement sealings (SKU 75005726) including grease for optimal sealing. As a result, the rotor remains fully functional throughout its lifespan.
