Tubes, Capillary
Capillary tubes are either 100 or 90 mm in length and have an inside diameter of approximately 1.3 to 1.4 mm. You can select from tubes that are open on both ends (used for spotting TLC plates) or closed on one end (used for melting point determinations).
Tubes, Centrifuge
Centrifuge Tube, Borosilicate Glass
Uniform glass distribution in the wall, taper, and bottom to improve mechanical strength and prevent the formation of failure-causing stress regions during centrifuging. GP6073 has white enamel graduations upward from the tip. Beaded rim; conical.
