Buret Card A buret card ought to have a black streak with a distinct horizontal zone of black against white. Moreover, when held behind the buret, the upper limit of the black streak ought to be placed just under the meniscus, so that the bottom of the meniscus can be seen distinctly against a narrow zone of white. Meniscus Black Streak Buret Card Buret Notes: ¾ A 50 mL buret can be read to ± 0.01 mL, but in order to be able to interpolate to the last digit, the perpendicular line of sight must be followed with meticulous care. ¾ Placing the black streak just under the meniscus is more repeatable than at some variable distance, the close placement is recommended.
