These 50 mL PYREX® tubes have a beaded rim and are fabricated from specially selected tubing for product durability. Engraved white-filled graduations at 25 and 50 mL.

This 50 mL PYREX® tube is for general hospital laboratory work. It was designed by Dr. F.N.L. Taylor, Boston City Hospital, for determinations involving multiple calibrations and for carrying out digestions. Graduated at 12.5, 25, 35 and 50 mL, and supplied with a durable, white enamel marking spot.

These 150mmm long PYREX® hybridization tubes have a 35mm inner diameter (I.D.) and are designed for use in hybridization chambers. They come with Corning® standard GL 45 orange plug-seal caps (No. 1395-45LTC). A silicone O-ring (No. 1395-OR) is used to ensure a leak-resistant seal. An optional Corning vented membrane cap (No. 1395-45LTMC) is available for low temperature assays.

These 15 mL PYREX® conical centrifuge tubes have white enamel graduations and are graduated upward from the tip in 0.1 mL divisions. The No. 13 Standard Taper pennyhead stopper is solid glass.

These 5 mL PYREX® conical centrifuge tubes have white enamel graduations and are graduated upward from the tip in 0.1 mL divisions. The No. 9 Standard Taper pennyhead stopper is solid glass.

These 50 mL PYREX® conical centrifuge tubes have white enamel graduations and are graduated upward from tip to 10 mL in 0.5 mL divisions, and from 10 to 50 in 1 mL divisions. The No. 16 Standard Taper pennyhead stopper is solid glass.

These 15 mL PYREX® conical centrifuge tubes have sharp, black enamel graduations and markings. The tubes are the same size and shape as our Nos. 8060 and 8080. They have precision formed tips and uniform walls throughout for a high degree of accuracy and mechanical strength.

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.
