Mechanical pipettes vs. electronic
Choosing between mechanical pipettes and electronic pipettes may seem quite daunting but at CAPP we make the choice easy. CAPP mechanical pipettes are a great option for budget-restricted laboratories as they maximize savings without compromising scientific output. Mechanical pipettes are faster to set up and make it easy to transfer small volumes with ease. Electronic pipettes are great for speeding up multi-sample liquid transfers. With automated dispensing and programmable features, CAPP electronic pipettes increase efficiency by optimizing pipetting workflows.

How to select a mechanical pipette?
Mechanical pipettes are among the most frequently used laboratory instruments, and it is important to choose a mechanical pipet that will integrate well with your workflow. At CAPP we recommend selecting a mechanical pipette with excellent accuracy and precision. These two factors will make sure your liquid transfers are highly accurate and less error prone. To determine this, check the manufacturer's website for proof of independent quality certification. Next, it is important to select a mechanical pipet with excellent ergonomics such as the CAPPAero multichannel pipette
. An ergonomic pipette will minimize the risk of strain or injury as you transfer liquids. Additional factors to consider include pipetting capacity, sample throughput, and liquid viscosity, among others. Scroll down to see the overview of CAPP mechanical pipettes.
How to use a mechanical pipette?
Using a CAPP mechanical pipette is as easy as pressing a plunger and aspirating. Seriously, it is that easy! Start by adjusting the volume control to the required volume. Place your thumb on the plunger of the mechanical pipet, making sure to keep your hand wrapped securely around the body of the pipette. With your free hand, open the box with pipette tips
and gently load a tip by pressing the nose cone onto a tip. Close the tip box and press the plunger to the first stop before lowering the loaded tip into the liquid to be transferred. Pre-wet the tip for 3-5 seconds and release the plunger gently. Once loaded, release the liquid into the desired container by gently pressing the plunger of the mechanical pipette to the second stop. Eject the disposable tip by pressing the ejector hook on your mechanical pipette.
Ergonomics of CAPP mechanical pipettes
CAPP mechanical pipettes offer excellent ergonomics for industry-leading pipetting comfort. A contoured body provides users extra comfort when handling CAPP mechanical pipettes. Additionally, CAPP mechanical pipettes have a low thumb load to minimize the risk of repetitive strain injury (RSI) when aspirating liquids. The piston stroke on each mechanical pipette is precision engineered for smoothness and thus it also lowers the risk of RSI. CAPP mechanical pipettes also feature a robust and lightweight chassis that allows users to transfer liquids for extended periods without getting fatigued.

How to fix a mechanical pipette error?
Mechanical pipette error can be a huge source of frustration for scientists and technicians alike. This often requires repeating long and tedious protocols to correct the error. By following a few guidelines, you can reduce the incidence of mechanical pipet error and increase your pipetting accuracy every time. Firstly, learning good pipette technique will eliminate one of the biggest sources of error - the user. Regularly servicing mechanical pipettes will keep them in calibration for longer, reducing error and increasing accuracy. Store your mechanical pipettes upright on the bench to prevent liquid from moving into the shaft, potentially damaging the interior. Use high-quality pipette tips
to eliminate improper sealing between the tip cone and the pipette tip as this will increase the chances of mechanical pipette error.
Cleaning and preventing contamination with a mechanical pipette
CAPP mechanical pipettes are designed to minimize the chances of sample contamination but when accidents happen, the pipettes are easy to clean. For routine maintenance, rubbing the mechanical pipette with water and a mild detergent will remove most contamination. Alternatively, you can use 60-70% ethanol for even faster decontamination. The external and internal materials used to manufacture CAPP mechanical pipettes are also autoclave-ready. This means that you can simply add CAPP pipettes to your autoclaving workflows for fast and effective sterilization of each mechanical pipette. To keep your mechanical pipette free of contamination we also recommend using ExpellPlus filtered pipette tips
What are the types of mechanical pipettes?
Mechanical pipettes are categorized into two major categories i.e., air displacement pipettes and positive displacement pipettes. Air displacement pipettes are the preferred choice for most laboratory liquid transfers because of their wide range of application. Positive displacement mechanical pipets are less common because they are highly specialized for handling challenging liquids. Modern air displacement mechanical pipettes function by drawing liquid into plastic pipette tips
with an air pocket between the plunger and the liquid to be transferred. The air pocket creates a push or pull effect on the liquid, facilitating transfer. Air displacement pipettes come in a range of form factors including single-channel
varieties. Visit our helpful guide
to learn more about the different types of mechanical pipets.
Single- or multichannel mechanical pipette?
CAPP mechanical pipets come in single-channel and multichannel varieties, and they are designed for different purposes. Single-channel mechanical pipets are an excellent choice for many low-throughput liquid transfers in the laboratory. This includes all single-tube applications, large volume transfers (>1ml) and certain specialty applications that require high-level motor skills (e.g., gel loading). Multichannel mechanical pipettes are the best choice for high throughput liquid transfers involving multi-well sample plates. Examples of such applications include PCR plate reaction preparations and PCR strip transfers. As their name suggests, multichannel mechanical pipettes allow users to increase their efficiency by transferring liquids from reagent reservoirs into multiple sample wells all in one go.

can improve your lab's efficiency.
Fixed or variable mechanical pipette?
Most mechanical pipettes feature an adjustable volume mechanism that allows users to transfer variable volumes. Variable volume mechanical pipettes offer excellent flexibility and cost savings by reducing the number of mechanical pipets required on a workstation. However, variable volume pipettes are prone to user error, and this can reduce their accuracy and reliability in volume-sensitive applications. In such use cases, fixed volume mechanical pipets offer greater reliability as they always transfer a fixed volume of liquid with each aspiration. Fixed volume mechanical pipettes are also an excellent choice for routine protocols that require transferring a set volume of liquid. CAPPTrio fixed volume mechanical pipettes
combine the best of both worlds by offering interchangeable fixed volume knobs for quick and easy switching between volumes.
