Sample container cap with centrifugation status indicator device

A sample container cap comprising:

• a sample cap body capable of covering an opening of a sample container;
• and
• a centrifugation status indicator device in the top of the sample cap body, wherein the centrifugation status indicator device comprises a pressure sensitive device extending in a first direction and transparent cylindrical elements that contact the pressure sensitive device and that extend perpendicular to the first direction of the pressure sensitive device, wherein the transparent cylindrical elements are configured to press onto the pressure sensitive device during centrifugation.

A method comprising:

• attaching a sample container cap comprising a sample cap body, and a centrifugation status indicator device in the top of the sample cap body, to a sample container body containing a sample;
• and
• centrifuging the sample in the sample container body, wherein the centrifugation status indicator indicates a status of centrifugation, wherein the centrifugation status indicator device comprises a pressure sensitive device and transparent cylindrical elements that are perpendicular to the pressure sensitive device and contact the pressure sensitive device, wherein the transparent cylindrical elements press onto the pressure sensitive device during centrifuging the sample.
