Jyoti Bashyal, a graduate of the Central Office of Chemistry, is definitely an avid explorer with the molecular realm. Fueled by her fascination with chemical reactions and organic compounds, she navigates her subject's complexities with precision and keenness.
Pasteur pipettes are produced from glass. With its bulb-shaped leading, a Pasteur pipette resembles an archetypal liquid dropper. Pasteur pipettes are deemed quite inaccurate today. They are neither calibrated nor graduated, and are more normally used in biology – rather than chemistry – laboratories for a technique for transferring aqueous methods from a person container to a different.
