Viscosity Tubes

Specifications:

Cargille Viscosity Tubes are manufactured to the closest possible tolerances and then precisely measured for final selection.

Length: 114mm +/-2mm
Wall Thickness: 0.65mm
Tolerance, ID: +/-0.025
Composition: Soda-lime glass, flat-bottom
Score Height Tolerance: +/-0.5mm

Score Marks:
All Cargille Viscosity Tubes are permanently marked with two score marks, at 100mm and 108mm heights with the exception of Time-Test Viscosity Tubes, which have an additional score at 27mm. In compliance with ASTM D-1545, all score marks are measured from the center outside bottom of the tubes The score mark at 100mm represents the filling level and the 108mm score is used to fix the size of the air bubble in the tube by inserting a cork to this mark. The 27mm and 100mm scores on Time-Test Viscosity Tubes are used to time bubble rise. In instances where more than one viscosity tube size is used, in the same laboratory, an additional score is inscribed, on request, to differentiate between sizes.

Viscosity Tubes -TIME-TEST VISCOSITY TUBES, 10.65mm (ASTM-D-1545)

Cat. #: 44154

Time-Test Viscosity Tubes are frequently referred to as ASTM D-1545 Tubes, which originated from the adopted standard method of test for viscosity as described in ASTM D-1545* issued by the American Society for Testing and Materials. Time-Test Tubes are scored in three places, 27mm, 100mm and 108mm. The score mark at 27mm is used for a 73mm timed bubble travel. Time-Test Viscosity Tubes are also subjected to additional testing procedures to ascertain the 10.65mm bore which is very critical for precision measuring.

Viscosity Tubes - Class "G-10.65"

Cat. #: 44106

CLASS "G10.65"
Class "G-10.65" Viscosity Tubes are used principally for direct comparisons to Gardner Viscosity Standards. The tubes are inscribed at the 100mm and 108mm lengths. For bubble rate rise comparisons to Gardner Viscosity Standards, the following equivalency chart is provided:
Cargille Class "G-10.65" = Gardner Grade A Tubes
Cargille Class "V-10.75" = Gardner Grade B Tubes

Viscosity Tubes - Class "V"

Cat. #: 44100

Class "V" Tubes are the least expensive of the viscosity tubes. Their principal utility is for comparison to other samples or standards of known viscosities as prepared by the user.
Class "V" Tubes are the Cargille specific assigned sizes between 10.50 and 11.00mm, with the exception of the 10.65mm and Class "V-10.75"mm sizes. Within this range, a specific tube size will be assigned, recorded in the Cargille Master File for future reference on reorders to insure furnishing the identical tube size. The Class "V" Tubes are also inscribed at the 100mm and 108mm lengths.

Application: Critical color or turbidity comparisons are frequently affected by variations in the light path of the liquid sample. To minimize this "visual diluting" effect, tubes are available with bore sizes to +/-0.05mm to insure replicate volume comparisons under similar light path conditions.

Tubes unsuitable for viscosity applications are separated, sorted, matched and grouped in two ranges according to tube bore size. Although these tubes are not precision matched or scored, they are adequately matched in bore size for diversified use in general industrial and laboratory procedures.

High quality, short length corks properly fit viscosity tubes so that the small end is in firm contact with inside of tubes to prevent small extraneous bubbles from interfering with timed bubble movement.
