BALANCES, TORSION 



c 



No. 516. 



No. 522. 



In the Torsion Balance the twisting of a steel band takes the place of the knife edge fulcrum, and 

 this with its relatively short period of vibration makes the balance very rapid for accurate work, 



Among those listed below will be found balances for practically every laboratory purpose except 

 for the most precise analytical work. 



516. BALANCE, Torsion, Cream Test Balance. Enclosed in white enamelled box with index and 

 arrest, counterpoise beam with sliding weight inside operated from without. Object pan con- 

 structed especially for holding one milk or cream test bottle. Capacity, 1 bottle; sensibility, S 

 milligrams. Complete with one 9 gram and one 18 gram weight. Dimensions, 10 x &'/$ x 9 

 inches over all $20.00 



518. BALANCE, Torsion, Cream Test Balance. Same construction as above, but with each pan de- 

 signed to hold two cream test bottles. Capacity, 4 bottles; sensibility, 8 milligrams. Com- 

 plete with one 9 gram and one 18 gram weight 24.00 



520. BALANCE, Torsion, Grain Test, designed according to suggestions of the United States Depart- 

 ment of Agriculture expressly for determination of moisture in grain, according to Bulletin No. 

 99, United States Bureau of Plant Industry. Slide beam, 9 inches in length, graduated to 10 

 grams by l/10th; scoop, 10%x5%x2*^ inches with spout for pouring directly into flask; 

 weight plate, 4 inches in diameter; capacity, 1 kilogram; sensibility, 6% centigrams. Com- 

 plete with set of brass weights in block, from 5 grams to 100 ". 24.00 



522. BALANCE, Torsion, Grain Test, designed especially for grading corn according to the require- 

 ments of the Federal Corn Grades. Same construction as No. 520, but with 9 inch beam grad- 

 uated to furnish four simultaneous readings: 100% by %%, 200 grams by 2 grams, 8% ounces 

 by % ounce, and 70 pounds per bushel by 1 pound. These graduations render the balance use- 

 ful in grain laboratories for a great variety of purposes, such as moisture determinations; per- 

 centage of dirt, cracked and broken grains; bushel weight, etc 27.00
