The original Bostwick Consistometer is the preferred choice for measuring consistency, flow rate and  viscosity  in a variety of products. 

Use the Bostwick Consistometer on any viscous material such as sauces, salad dressings, paints, chemicals or cosmetics, to measure the distance a material flows in a given time interval. 

The Bostwick complies to Mill Spec R-81294D and ASTM F1080-93 and is made of stainless steel construction. NEXT DAY DELIVERY AVAILABLE!

ENGRAVED GRADUATIONS OF 0.5 cm DIVISIONS        Assures accurate results         Wear and smear resisatant

​ORIGINAL BOSTWICK CONSISTOMETER

For the determination of the flow of a standard volume of a semisolid or thick liquid under its own weight.

Reproducibility- within .5 cm with same operator and same sample.

NOTE: Viscous materials may vary in consistency, depending on the age of the sample, the temperature of the sample, and shear history.

SIMPLE OPERATION​

Fill the reservoir with about 100 ml,of a 250 ml prepared sample, and level off the top with a straight edge. 

The temperature of the device, and sample, should be the same.

Press down on the trigger to open the gate at the beginning of the time cycle. 

At the end of the selected time period, (5 MIN ASTM 1080) determine how far the material has flowed along the trough.

Take the maximum reading at the center of the trough, and the minimum reading at the edge of the trough, and average the values.

The average value is then compared against a previously determined standard.
