Test tubes - Falling number test tube

Special test tube for falling number method. The falling number (FN), also referred to as the Hagberg number or Hagberg–Perten number, is the internationally standardized (ICC 107/1, ISO 3093-2004, AACC 56-81B) and most popular method for determining sprout damage. With the falling number test, so-called weather or sprout damaged wheat or rye, which adversely affects bread-making quality, could be detected at the grain silo intake within a few minutes.

The falling number method is uncomplicated, but requires an apparatus which follows the international standards. Such an apparatus consists of a water bath, a test tube, a stirring rod, and a stirring device. The test instrumentation today is mostly automated.

For production of this tubes, we use Simax borosilicate glass. We allways check glass quality, dimensions and optical clarity.
