These 100 mL PYREX® 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 1.5 mL in 0.1 mL divisions. The body is graduated…

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

Uniform glass distribution in the wall, taper and bottom of these 50 mL PYREX® conical centrifuge tubes provides improved mechanical strength, prevents the formation of failure-causing stress regions during centrifuging and insures the highest degree of accuracy. The durable, white enamel scale is graduated from 0 to 10 mL in 0.5 mL divisions, and from 10 mL to 50 mL in 1 mL divisions. Tubes have pourout spout for easy decanti…

These heavy duty 40 mL PYREX® conical centrifuge tubes are made with increased wall thickness for greater mechanical strength. In order to conform to outside diameter and overall length limitations imposed by centrifuge rotors and supports, it has been necessary to reduce the capacity these heavy duty tubes. Tubes have pourout spout for easy decanting.
