KIMAX® Schellbach Auto-Zero Buret w/Three-Way PTFE Stopcock
Manufacturer: Kimble Chase
KIMAX buret with a filling tube at the stopcock and an overflow tube at the top of the buret that accept 1/4 inch I.D. flexible tubing. An automatic or self-zeroing buret must be read only at the apparent meniscus for which it has been calibrated when volumes are dispensed from zero to any other point. Use of true meniscus in this case would result in a lesser volume being dispensed than between any two other points of the same nominal volume. For greater accuracy, however a "buret reader" should be used to eliminate the exaggerated parallax problems. Stopcock for all sizes is 2. Scale is durable black ceramic enamel. Replacement stopcock is 41530F-2.
