Self-Zeroing Buret Kit
Makes any plastic or glass 25- or 50-ml buret self-zeroing, economically and easily. Saves you money over costly glass self-zeroing burets. No more funneling; hazardous, wasteful spills are eliminated. Can be used with almost all aqueous titrants. Set adjustable fill-tube to zero mark on buret. Squeeze bottle to fill buret* just above zero mark. Release and excess liquid returns to bottle and titrant falls to the zero mark. To switch to a different size buret, simply reverse the adapter.[…] Nunc

KIMAX® Schellbach Buret w/PTFE Stopcock & Dust Cap
Schellbach burets employ a blue line on a broader white band running vertically behind the scale to create an optical effect which causes the meniscus to assume an apparent form. The meniscus is read at the narrowest point of the blue line just above the true meniscus. KIM-KAP dust cap is included. Scale is durable black ceramic enamel. Kimble Glass
Polyethylene Automatic Burette
These burettes have easy to read blue graduations against a white background. The delivery end is fitted into a plastic push button stopcock that permits drop-by-drop delivery. A small screw clamp presets drop speed for repeat titration. A polyethylene filling tube extends from the top of the burette into the bottle reservoir. Bottle, screw cap, and round base are polyethylene. Graduation accuracy is Class B. Bel-Art
Self Zeroing Automatic Burette
Borosilicate glass burettes have white 0.1ml graduations and are mounted to a polyethylene screw cap and bottle. Squeezing the flexible bottle forces liquid into burette. Overfill drains back into bottle when pressure is released. The drain arm has a 2mm bore glass stopcock. Large, stable plastic base is separable from reservoir. Accuracy of burette is within 1% of total volume. Bel-Art
