TRANSFER PIPETTE Meaning and
Definition
-
A transfer pipette is a laboratory instrument used to accurately transfer small quantities of liquids. It is designed to be disposable, providing a convenient and hygienic solution for various scientific and medical applications. A transfer pipette typically consists of a slender plastic tube with an elongated tip at one end. The tip usually tapers to a fine point to facilitate precise measurements and allow for controlled dispensing.
To use a transfer pipette, the user attaches the bulbous end to the top of the pipette and squeezes it to create a vacuum. By immersing the tip into the liquid, the user can release the pressure on the bulb to draw in a specific volume of liquid. The volume is often indicated on the transfer pipette itself, making it easy for researchers to accurately measure and transfer precise quantities of liquids.
Transfer pipettes are commonly used in various scientific fields, such as chemistry, biology, and medicine. They are particularly valuable for tasks requiring high precision, such as preparing samples, performing dilutions, and dispensing reagents. Transfer pipettes offer several advantages, such as their disposable nature, which eliminates cross-contamination risks and simplifies the cleaning process. Additionally, their ergonomic design enables easy handling and reduces the probability of human error during liquid transfers.
In summary, a transfer pipette is a disposable laboratory tool used for transferring small volumes of liquids with high accuracy. It consists of a plastic tube with a narrow tip that allows controlled dispensing and precise measurements. Its versatility and convenience make it an essential instrument for a wide range of scientific applications.
Etymology of TRANSFER PIPETTE
The word "transfer pipette" is a combination of two terms: "transfer" and "pipette".
1. "Transfer" comes from the Latin word "transferre", which means "to carry across" or "to move". The word entered Middle English from the Old French word "transferer", maintaining its original Latin meaning.
2. "Pipette" originated from the French word "pipette", which meant a "small pipe" or "tube". It was derived from the Old French word "pipette", which referred to a "piece of pipe".
When combined, "transfer" and "pipette" describe a tool used to carry or move liquids from one container to another in a controlled manner.
