A Comprehensive Guide To Pipette Dropper: Types and Applications in the Lab

Posted on the 25th of Sep 2023 by Westlab

The importance of accurate and precise liquid handling cannot be overstated in scientific research and laboratory experiments. The pipette dropper is an indispensable tool for facilitating this process, offering a range of features that make it suitable for various applications. 

These scientific droppers offer unparalleled accuracy and precision in liquid handling, which is vital for the success of scientific experiments and medical tests. Besides being useful for accurate measurements, pipettes are also easy to use and comfortable to hold. They can provide years of reliable service with proper care and calibration, making them a valuable asset in any lab setting.

Choosing the right pipette dropper can be confusing, especially in Australia, where labs have strict rules and standards to follow. This guide is here to simplify things and help pick the best pipette dropper for the lab's needs.

What Are The Types Of Pippete Dropper Used In Laboratories?

Considering the multi-layered benefits of a pipette dropper, it is an irreplaceable scientific tool for research and experimentation. There are various kinds of droppers used in Lab Pipettes. Each serves a significant role in deducing results and precision. 

Here are a few common types of laboratory glassware that one may find in experiments.  

Mohr Pipettes

Mohr pipettes are crafted from glass and are meticulously calibrated to dispense specific volumes of liquid with high accuracy. They come with graduation marks indicating fixed volume points. Due to their precision, glass dropper pipette is often employed in quantitative work where measurements must be exact, such as in titrations. Their glass composition also offers good chemical resistance, making them suitable for handling various liquids.

Serological Pipettes

Serological Pipettes are versatile tools made of disposable plastic. Unlike Mohr pipettes, they are used for a broader range of activities, including transferring liquids, mixing samples, and dispensing reagents. They generally feature multiple graduation marks, which gives the user greater flexibility in using a volumetric pipette. Being disposable, they also minimize the risk of cross-contamination between samples.

Pasteur Pipettes

Named after the famous scientist Louis Pasteur, these are slender, long glass pipettes designed for high-precision tasks. They often transfer small volumes of liquid in applications that demand exactness, such as cell culture and microbiology work. Because they are made of glass, they offer the advantage of chemical resistance and can be sterilized for reuse in some settings.

Transfer Pipettes

Transfer pipettes are typically made of disposable plastic and are designed to transfer relatively larger volumes of liquid than serological Mastering Pipette Techniques. They do not usually offer the same level of precision but are convenient for tasks like making buffers and solutions where extreme accuracy may not be as critical. Their disposable nature also makes them practical for one-time use applications.

Dropper Bottles

Dropper bottles are unique because they are fitted with a dropper for dispensing liquids in droplet form. They are useful for applications that require the addition of reagents in small, controlled amounts, such as in microplate wells. They are also commonly used for dispensing essential oils and other concentrated liquids.

Each type of pipette dropper has its benefits, and choosing the right one can significantly impact the efficiency and precision of lab work. The ideal laboratory glassware will depend on the specific requirements of all tasks.

Factors To Consider Before Getting A Pipette Dropper

Selecting the right pipette dropper for a scientific lab requires careful consideration of various factors. 

Here is a guide to some of the critical aspects one should consider. 

Purpose and Application

Understand the specific needs of laboratory experiments or procedures. Whether the lab requires high precision for quantitative work or a versatile tool for multiple tasks will determine the type of pipette dropper one should choose.


Consider the material the pipette is made from—glass or plastic. Glass is resistant to chemicals but is fragile. In contrast, plastic is durable but might not suit all types of chemicals.

Volume Requirements

The volume of liquid one needs to transfer is critical. Pipettes come in various sizes, from micro-pipettes for minimal volumes to larger transfer pipettes. Ensure the pipette one may select is calibrated for their volume needs.

Accuracy and Precision

One may opt for calibrated, high-quality pipettes like Mohr or serological pipettes for tasks requiring high accuracy and precision. On the other hand, tasks that do not need exact measurements allow for more basic types like Pasteur or transfer pipettes.

Budget Constraints

Pipettes range from affordable, disposable options to more expensive, specialized types—balance budget constraints with accuracy, durability, and compliance needs.

Maintenance and Calibration

Think about the long-term costs and procedures for maintaining a pipette. Some require regular calibration and maintenance, which might increase operational costs over time.

Sterilization and Contamination Risks

Evaluate whether the glass dropper pipette can be sterilized or is disposable to prevent cross-contamination, which is especially important in sensitive applications like cell culture or medical diagnostics.

Vendor Reliability

Finally, consider purchasing from reputable vendors offering warranties, good customer service, and opportunities for demonstrations or samples.

Assessing these factors will ensure that choosing a pipette dropper that meets specific needs and contributes to more efficient and accurate laboratory work.

There are many different pipette dropper, each suitable for different kinds of work. The right choice will not only elevate the accuracy and efficiency of work but also ensure compliance with the rigorous standards and regulations governing Australian labs.
