Avoid outside contamination with this highly accurate closed system.

• Borosilicate glass construction
• HDPE screw cap
• Built-in overflow

Borosilicate glass burettes have white, 0.1 mL graduations and are mounted to a high-density polyethylene screw cap

Built-in overflow automatically drains excess liquid back into reservoir. The glass stopcock has a 2 mm bore. Large, stable plastic base can be detached from reservoir. Accuracy of burette is within 1% of total volume. Graduation accuracy is Class A.

Squeezing the flexible polyethylene bottle forces liquid into the burette.
