The test has to be performed using the specific liquids and the suitable hot plate listed within the accessories. We propose three hot plate solutions:
  • 10-D1402/A Standard hot plate, 160 mm dia., 1000 W. More economical solution thus conforming to ASTM standards.
  • 81-B0145/C1 Hot plate with centering/protection device for 81-B0145 Ring and Ball apparatus. More professional solution.
  • 81-B0145/D Hot plate with magnetic stirrer, conforming either to ASTM or to EN 1427 Standards which require the water stirring for more temperature uniformity.
We also propose a fully automatic model. See \#automatic-ring-and-ball-apparatus\#.
