Offers on/off and fine control so accurate that it replaces stopcocks in many applications. Can be installed without disconnecting tubing or interrupting operation. Molded of Acetal plastic, the clamp is autoclavable and resistant to acids, alkalis and organic solvents. Accepts flexible tubing up to 14mm (1/2") O.D.

Avoid outside contamination with this highly accurate closed system. Borosilicate glass burettes have white 0.1ml graduations and are mounted to a high-density polyethylene screw cap. Squeezing the flexible polyethylene bottle forces liquid into the burette. Built in overflow automatically drains excess liquid back into reservoir. The glass stopcock has a 2mm bore. Large, stable plastic base can be detached from reservoir. Accuracy of burette is within 1% of total volume. Graduation accuracy is Class A.
