may lead to slight variations in the test results. To eliminate this error the tubes shoulbe
placed in the chamber with the same orientation each time. The orientation of the
tubes in the chamber is controlled by use of a tube positioning ring. For improved
accuracy and precision, especially at low concentrations, the tubes should always be
used with a positioning ring. (See page 22)
