Microliter Centrifuges

Microliter centrifuges are designed for processing very small samples at very high speeds. This is usually used for kits for isolating DNA and RNA. These steps are necessary in order to analyze the DNA and RNA or process them further for polymerase chain reaction (PCR). 

Sealing certificates are available directly from us for all biocontainment rotors. The seal is tested and certified by an external institute (TÜV in Germany, for example) in accordance with the laboratory equipment standard EN 61010-2-020.

For some PCR protocols, filtration is prescribed where filter sleeves are centrifuged in 2-ml test tubes. The sample liquid that passes through the filter during the filtering/centrifuging procedure is collected in the 2-ml test tubes. A common problem frequently encountered is the fact that the caps of the test tubes no longer fit because of the filters, so the test tubes have to remain open during centrifugation. The caps are often tear off in such cases, or alternatively are cut off before centrifugation. 

To avoid this and prevent the caps having to be cut off before centrifugation, the angle rotor for spin column kits has been designed so that the caps can be securely positioned in place. The caps neither tear off, nor is it necessary to cut them off.
