Automatic Burette is self-zeroing and provides a completely closed system. Flexible vinyl tubing connects from the burette top into the reservoir. Squeezing the bottle fills the burette just over the zero line, and excess liquid is returned to the reservoir bottle. The Burette is made from high-quality borosilicate 3.3 glass and features a Schellbach strip and blue graduations for easier visualization of readings. Bottle reservoir is made of durable polyethylene for high chemical resistance and no risk of breakage. It sits snuggly in a durable polyethylene base to prevent tipping. The burette features a push button style stopcock and screw clamp for setting drop speed for repeat titration. Exact spout tip provides precise delivery of fluids.
