What pipet does this describe?
a. calibrated either to contain (TC) or to deliver (TD) stated volume t. do not overfill
b. To Contain: rinse several times with reagent and blow out i. blow-out has continuous
etched rings
c. To Deliver: the liquid is allowed to drain against the side of the receiving vessel i. self-
draining has no rings it.
TD types:
=:> air-propelled sample (no need to change tips between samples)
=:> wire and tip inside glass pipet (no need to change tips between samples) -
