CAPP Piston Pipettes - from theory to practice

The 21st century has seen a rapid increase in life science research. Several important discoveries are made each year. Scientists publish thousands of innovative research papers each month. Although there are several reasons for this growth trajectory, we will focus on one often unnoticed factor. The humble piston pipette that graces many lab workbenches has played a huge role in simplifying research workflows. In this article, we will trace the history of the piston pipette. We will also highlight how CAPP's air displacement pipettes can help you achieve more in your research.

Piston Pipettes: A brief history

Piston pipettes have not always been as common in life science labs as they are today. Scientists pipetted by mouth for much of modern scientific history. One scientist out of Marburg in Germany changed this in the middle of the 20th century. By modifying a syringe, Heinrich Schnitger developed the first piston pipette. Beginning with this simple air displacement pipette, manufacturers like CAPP have continued to improve the accuracy and precision of piston pipettes. We believe that modern piston pipettes have been the fuel behind the growth of life sciences in the modern era.

Air Displacement Pipettes: The basics

Among modern piston pipettes, air displacement pipettes are the most common. Air displacement pipettes feature a piston enclosed within the pipette assembly.  An air cushion separates the plunger from the liquid to be transferred. With good pipetting technique, this cushion will protect your samples from contamination. In early piston pipettes, the air cushion would be affected by changes in the environment (i.e., humidity, temperature, etc.). Modern air displacement pipettes from CAPP can be used in a wide range of environments with high precision and accuracy. Additionally, air displacement pipettes are affordable and readily available.

Positive displacement: Piston Pipettes for the demanding times

Some piston pipettes use a positive displacement mechanism for transferring liquids. Although they are not commonly used for most lab work, positive displacement pipettes are great for transferring viscous liquids. The piston of positive displacement piston pipettes is in the disposable tips. Here, the piston is in direct contact with the liquid to be transferred. Positive displacement pipettes are a wonderful choice for handling viscous liquids and corrosive reagents. However, for most liquids that are handled in the modern lab, air displacement pipettes are the better choice.

Which Piston Pipette should I choose?

Selecting the best piston pipette can be challenging with a broad range of options on the market today. At CAPP, we have put in the hard work for you so that you can focus on your research while we innovate on the tools. All CAPP's piston pipettes are manufactured to meet the rigorous quality requirements of ISO 8655 guidelines. CAPP's portfolio also includes several air displacement pipettes and a positive displacement piston pipette for the difficult liquids. Designed for accuracy and precision, CAPP's pipettes help you get your data out faster. In the next section, we will provide a brief overview of CAPP's extensive range of air displacement pipettes and positive displacement piston pipettes.
