Mouth Pipette: An Overview

A mouth pipette is a laboratory instrument designed for the transfer of small volumes of liquid. It is a simple yet essential tool in various scientific fields, enabling precise handling of liquids in experiments and procedures. The design of a mouth pipette typically includes a narrow tube that can draw up and release liquids through mouth suction pipette action.

Types and Applications

The versatility of the mouth pipette is evident in its range of types, each suited for specific tasks. From the standard single-channel pipettes to wide mouth pipette models, these tools are integral in tasks such as filling fountain pen converters or cartridges, preparing solutions, and transferring tinctures. The oral pipette is particularly useful in laboratory settings, where precise volume measurements are crucial.

Features and Materials

Mouth pipettes are designed with features that cater to ease of use and accuracy. They come with gradations on their sides to assist in measuring the dispensed liquid quantity. The materials used in manufacturing these pipettes are chosen for their durability and resistance to chemicals, ensuring that substances like solvents, acetone, and HCL can be handled safely.

Advantages of Using Mouth Pipettes

The use of a mouth pipette offers several advantages in the laboratory. Its ability to provide controlled volume adjustment is critical for precision tasks. Furthermore, the option for wide mouth pipette tips allows for the handling of viscous liquids or larger particulate samples, expanding the range of applications.

Considerations for Selection

When selecting a mouth pipette, it is important to consider the specific needs of the task at hand. For instance, pipetting by mouth is not recommended for toxic or hazardous substances, and in such cases, alternative pipetting methods should be employed. Additionally, the quality of the pipette is paramount to ensure accurate measurements and longevity of the equipment.

Safe Practices in Pipetting

While the mouth pipette is a valuable tool, it is essential to follow safe laboratory practices. The adage "don't pipette by mouth" is a safety guideline to prevent exposure to harmful chemicals. Always use appropriate safety equipment and follow established protocols to ensure a safe working environment.
