These 100mL PYREX pear-shaped centrifuge tubes are used for phosphorus determinations in iron and steel. The lower stem is graduated upward to 1mL in 0.05mL pisions. The body is graduated from 1mL to 5mL in 1mL pisions; from 5mL to 50mL in 5mL pisions; and from 50mL to 100mL in 10mL pisions.

These 100mL PYREX庐 pear-shaped centrifuge tubes are used for determination of water and sediment in petroleum products. They are fabricated from mold-blown blanks to insure uniform shape and greater mechanical strength. The scale and figures are durable white enamel which stand out clearly against the red color-band on these Lifetime Red tubes. The stem is graduated from 0 to 1.5mL in 0.1mL pisions. The body is graduated from 1.5mL to 5mL in 0.5mL pisions; from 5mL to 10mL in 1mL pisions; and at 15, 20, 25, 50 and 100mL. Reference: ASTM D-96 and D-1966.

These 100mL PYREX conical centrifuge tubes have white graduations and are used in accordance with standard methods of testing for water and sediment in petroleum products. Tubes are calibrated "to contain". They are graduated upward from 0 to 0.5mL in 0.05mL intervals; from 0.5 to 2.0mL in 0.10 intervals; from 2.0 to 3.0mL in 0.20 intervals; from 3.0 to 5.0mL in 0.50 intervals; from 5.0 to 10.0mL in 1.0 intervals; from 10.0 to 25.0mL in 5.0 intervals; from 25.0 to 100.0mL in 25.0 intervals. Reference: ASTM D-96.

These 100mL PYREX conical centrifuge tubes have white graduations and are used in accordance with standard methods of testing for water and sediment in petroleum products. These tubes are graduated upward to 0.5mL in pisions of 0.05mL; from 0.5mL to 2mL in pisions of 0.1mL; from 2mL to 3mL in pisions of 0.2mL; from 3mL to 5mL in pisions of 0.5mL; from 5mL to 10mL in pisions of 1mL; from 10mL to 25mL in pisions of 5mL and at 50, 75 and 100mL.
