Zeitfuchs Cross-Arm Viscometer

Brand: Ramin' USA Product Code:
VIS-CA

The Cross-Arm operates differently than the modified Ostwald and suspended – level designs in that the liquid sample is caused to flow through a capillary restrictor, and then into a volumetric timing bulb which is clean and dry, and has not previously been wetted by the sample. For this reason, only one timing may be done per sample. In order to repeat a test, the tube must be thoroughly cleaned with solvent (such as Acetone), using a vacuum to move the solvents, and finishing the passage of dry air until the tube is completely dry and ready for the next sample. Approximately 3ml of sample is introduced into the large tube at the top while viscometer is mounted in the bath.
