Test tube holder for Hanna photometer

Test tube holder for Hanna photometer type "Checker" or "Ion Specific Meter" or all test tubes with diameter 18.6 mm.

How quickly it happens: during the filling of the test tube, an awkward movement causes the tube to fall over. The result is a chemical puddle and a wasted test. The AquaCare test tube holder secures the glass and simplifies the filling procedure.
