The Thermo Scientific MicroCL PCR 8×8 screw-lid fixed-angle rotor is a dedicated rotor for PCR strips on the MicroCL 17 and 21 microcentrifuges. Moreover, this rotor offers 8 positions for PCR strips of 8 tubes each. In addition, the PCR 8×8 reaches a maximum speed of 14,800 rpm and an RCF of 17,100 x g. As a result, you process up to 64 x 0.2 mL PCR tubes per run without re-pipetting.
Furthermore, the PCR 8×8 stands out with its specific design for PCR strip format. Therefore, you centrifuge 8-strip PCR tubes directly without adapters. Moreover, this rotor is ideal for PCR pre-spin protocols where liquid needs to be consolidated at the bottom. Additionally, the design promotes efficient processing of high-throughput PCR workflows.
In addition, the PCR 8×8 accommodates a simple screw-on lid for sample protection during centrifugation. Subsequently, you screw the lid onto the rotor with a half turn. Moreover, this lid prevents PCR tube caps from popping open during runs. As a result, samples remain safely within the tubes at maximum rotor speed.
Finally, the PCR 8×8 is ideal for molecular biology routine and high-throughput PCR preparation. Therefore, this rotor is the standard choice for laboratories that regularly use 8-strip PCR tubes. As a result, you combine high-throughput PCR processing with simple operation and affordable acquisition.

Dedicated PCR strip rotor for the Thermo Scientific MicroCL 17 and 21 microcentrifuges. With a capacity of 8 PCR strips (64 x 0.2 mL) and 17,100 x g RCF, the PCR 8×8 offers maximum throughput for PCR pre-spin protocols. Equipped with a simple screw-on lid for sample protection without adapters. Ideal for molecular biology and high-throughput PCR preparation.








The MicroCL PCR 8×8 screw-lid rotor is compatible with the MicroCL 17, 17R, 21 and 21R microcentrifuges. Moreover, this rotor works on both ventilated and refrigerated models of the MicroCL series. In addition, this rotor reaches a maximum speed of 14,800 rpm on all compatible models. As a result, the PCR 8×8 delivers consistent performance across the entire MicroCL platform.
The PCR 8×8 accommodates 8 PCR strips of 8 tubes each per run. Moreover, you process up to 64 x 0.2 mL PCR tubes in one centrifugation. In addition, this is the highest capacity for PCR strip format on the MicroCL series. As a result, you accelerate high-throughput PCR protocols significantly.
The PCR 8×8 uses a screw-on lid because PCR pre-spin protocols do not require biocontainment certification. Moreover, a screw-on lid is sufficient to keep PCR tube caps in place during centrifugation. In addition, this configuration lowers the acquisition cost. Therefore, choose a PCR rotor with ClickSeal biocontainment (SKU 75003440) when processing infectious PCR templates.
The PCR 8×8 has a capacity of 64 x 0.2 mL with screw-on lid, whereas the PCR 4×8 ClickSeal (SKU 75003440) has a capacity of 32 x 0.2 mL with biocontainment. Moreover, the PCR 8×8 reaches 17,100 x g, compared to 16,200 x g for the PCR 4×8. Conversely, the PCR 4×8 ClickSeal offers certified biocontainment for biohazardous samples. Therefore, choose the PCR 8×8 for maximum throughput and the PCR 4×8 for biocontainment.
The PCR 8×8 is highly suitable for PCR pre-spin protocols where droplets need to move to the bottom. Moreover, this rotor is the standard choice for high-throughput PCR preparation. In addition, this rotor accommodates molecular biology routine with 8-strip PCR tubes. Furthermore, this rotor is suitable for reverse transcriptase reactions and qPCR sample preparation.
Yes, the screw-on lid (SKU 75003406) is compatible with multiple MicroCL rotors. Moreover, this lid works on the PCR 8×8 (75003489), the Dual Row 18×2.0/0.5 mL rotor (75003418) and the 36×0.5 mL rotor (75003436). In addition, this is a standardised replacement part for laboratories with multiple MicroCL rotors. As a result, you simplify inventory management of replacement parts.
