Thermo Fisher says that each delivers improved versatility in rapid, small volume processing of samples including viruses, cellular organelles, lipoproteins, nucleic acids and nanoparticles. Both new micro-ultracentrifuge models offer an expanded volume range, accommodating tubes from 0.2 mL to 30 mL. These systems use a drive system, providing maintenance-free performance and rotor imbalance protection for reliable performance.

According to Thermo Fisher, the Sorvall MTX 150 is up to 20% smaller than other benchtop models in its class and makes almost any separation possible with a centrifugal force in excess of 1,048,000 × g. Thermo Fisher adds that it has a sleek design and quiet operation (45dBA), which provides a comfortable working environment. The maximum rotational speed of 150,000 rpm can be achieved in just 80 seconds. In addition, a LCD touch-screen interface simplifies operation while providing a range of operating features.

Thermo Fisher adds that the new Sorvall MX series offers the same versatility as the Sorvall MTX 150. It is available in two versions with maximum speeds of 150,000 rpm or 120,000 rpm, and offers a small footprint of 2.3 square ft (0.21 sq metres), in combination with minimal noise (below 48 dBA).
