Question
Chapter 3.2, Problem 10E
Interpretation Introduction
Interpretation:Consequences of use of no preheated Pasteur filter and filter-tip pipets before filtration should be determined.
Concept introduction:Pasteur pipet consists of glass tube that is designed in such way that its one end forms tip through which liquid is allowed to enter with help of latex suction bulb. Pasteur filter-tip is modified version of Pasteur pipet; it is useful to transfer liquids with volatile components.
