MOHR PIPETTE Meaning and
Definition
-
A Mohr pipette is a type of volumetric glassware used in a laboratory setting for precise measurement and transfer of liquids. It is named after the German chemist Karl Friedrich Mohr, who played a significant role in the development of analytical chemistry.
The Mohr pipette is a graduated glass tube with a tapered tip at one end and a small bulbous portion at the other end. The tapered tip allows for controlled delivery and dispensing of liquids, while the bulbous section serves as a measuring chamber.
To use a Mohr pipette, the liquid to be transferred is drawn into the pipette by creating a vacuum using a rubber bulb or a pipette filler. The liquid is carefully aspirated until the desired volume is reached, with the meniscus of the liquid aligned with the graduation mark on the pipette. The liquid can then be accurately transferred to another container by gently releasing the vacuum pressure.
The volumetric capacity of a Mohr pipette is typically indicated on the glass tube, and they come in various sizes ranging from 1 mL to 100 mL or more. Mohr pipettes are designed for measuring and transferring liquids that do not react with or adsorb to glass surfaces, making them suitable for a wide range of applications in chemistry, microbiology, and pharmaceutical research.
Overall, a Mohr pipette is an essential tool in the laboratory, enabling precise liquid measurements and transfers with a high degree of accuracy and repeatability.
Etymology of MOHR PIPETTE
The word "mohr pipette" is named after the German chemist Karl Friedrich Mohr. Mohr pipettes are a type of volumetric pipette, which he developed in the 19th century. The term "mohr" is derived from the German surname Mohr, and it is common in scientific naming conventions to name equipment or techniques after their originators or notable contributors.
