Delivery pipette - -the delivered quantity of liquid corresponds to the capacity printed on
the pipette
Tare - -a deduction from the gross weight of a substance and its container made in
allowance for the weight of the container
Balance beam - -scales do not measure weight, instead they value mass
Electronic - -scales determine the weight of an object
Meniscus - -a lens that is convex on one side and concave on the other
Accuracy - -refers to the closeness of a measured value to a standard or known value
Presicion - -refers to the closeness of two or more measurements to each other
