Default Value: Null

Pattern Description: Greater than 0 seconds or Null.

Programmatic Pattern: GreaterP[0*Second]

Wait 5 Minutes before the second transfer:

When performing a Manual SamplePreparation, Engine will display a timer telling the operator to wait for 10 minutes before performing the next unit operations. However, there will be additional time involved in gathering the instruments/tips required for the second transfer, after the Wait unit operation is finished. Therefore, when performing a Manual SamplePreparation, the amount of time between the first and second transfer will be greater than, but not exactly 10 minutes (on the minute level of precision):

When performing a Robotic SamplePreparation, the liquid handling robot will wait precisely 5 minutes between the first and second transfer. Robotic sample preparation allows for second level precision when performing unit operations:
