Environmental Factors Affecting Pipetting Accuracy and How to Control Them?

Pipettes are used in the laboratory setting which can be helpful for carrying out various experiments, it can be helpful for elevating the experimenting standards. This will play a significant role in seamlessly transferring liquid from one laboratory equipment to the other.

Therefore, there can be various environmental factors which can affect pipetting accuracy. Eventually, there are various ways to control the pipettes while managing liquids during an experiment. This will elevate the overall **pipetting** standards throughout the laboratory experiment.

Environmental conditions are not only affecting the overall climate change, but it is also creating a gap in getting pipetting accuracy which laboratory technicians crave. This blog is all about the environmental conditions that may affect the pipetting accuracy throughout the experiment and ways which can be followed for controlling inaccuracies.

Factors Affecting Pipetting Accuracy and Ways to Control

Here are the environmental factors which can be looked upon while carrying out an experiment. These may prevent pipetting inaccuracy. Following this, there are also the ways which can be observed for controlling and achieving accuracy.

• Temperature

When the experiment is carried out in the laboratory, there can be instances where you may experience thermal expansion which can lead to temperature differences between the pipette, the tip, and the liquid. These can create a way for causing thermal expansion and contraction of the air cushion within the pipette. It will eventually lead to inaccurate volume delivery throughout the experiment.

When a problem arises, there are ways which can prevent the inaccuracies happening due to temperature changes. One of the ways which can be followed is that all the **liquid handling instruments** involved in an experiment such as samples and pipettes should equilibrate to the same temperature. This will play a significant role in reducing the temperature difference and elevate pipetting standards for an experiment.

• Humidity

Along with the temperature changes, humidity at play can also significantly affect the pipetting accuracy. The low humidity in the pipette may trigger enhanced evaporation of volatile liquids. Eventually, it will affect the final volume and it will leave a mark while conducting an experiment.

There are ways to prevent humidity from collecting in the pipetting tips, this leads to the process of preventing evaporation by pre-wetting the pipette tip. It will play a significant role in increasing humidity inside the tip and reducing evaporating. Eventually, you can seamlessly carry out the experiment.

• Pressure

Among all the inaccuracies in the laboratory while conducting an experiment, there are pressure changes in the barometer during an experiment. This will lead to fluctuations in barometric pressure, which can also affect the volume dispensed. It can also affect the liquid flow from pipette filler to the laboratory equipment.

The pressure changes along with the barometric inaccuracies can be controlled by maintaining an environment during an experiment. This can also play a significant role in maintaining a stable lab environment which can help to minimize these effects. It will also eventually reduce the pipetting inaccuracies.

Control Environment factors and improve Pipetting accuracy

Can laboratory standards be maintained by controlling environment factors which can improve pipetting accuracy? absolutely yes. There are various ways for maintaining environmental standards which can improve environmental accuracy and provide consistent results.

• Maintain a Stable Environment

There are various ways to maintain a stable environment in a laboratory while carrying out an experiment. These ways contain controlling the temperature, maintaining it up to the consistent levels throughout the experiment. This will play a significant role in maintaining the well-controlled laboratory environment.

Therefore, the humidity control can be a way to maintain the appropriate levels, which will reduce evaporation. This will enhance the experiment standards in the laboratory and also can prevent the liquid loss throughout the experiment. It would maintain the pipetting accuracy throughout the experiment.

While carrying out an experiment, you can also experiment with significant pressure changes due to the environment being not in sync. This can eventually be difficult to control and can lead to potential pressure fluctuations and their impact. It can be controlled by including external pressure controllers such as barometers, which will elevate your experiment standards.

• Equilibrate Sample and Pipettes

While conducting an experiment, you can initially equilibrate the sample and pipettes at the same temperature before pipetting. This will lead to elevating the experiment standards. This will promote laboratory equipment to work in sync throughout the experiment.

• Use Proper Pipetting Techniques

Through the experiment, there are ways to maintain the consistent speed and force. It will use a consistent speed and force when depressing the plunger. This will reduce the liquid loss throughout the experiment standards. Along with this, you can also check for the immersion depth, through this it will keep the tip immersed to the correct depth in the liquid throughout the experiment.

Along with this, check for the tip angle while conducting an experiment. It will support through the process which can be carried out by holding pipette vertically during aspiration and during the usage of **bottle top dispenser**. This would also play a significant role in maintaining the experiment standards, eventually providing accurate results.

Pre-wetting techniques while using pipette can play a major role in maintaining the experiment quality. This will also increase humidity, which will eventually reduce evaporation. It will help you seamlessly transfer liquids from one equipment to another.

• Consider Using Positive Displacement Pipettes

While conducting an experiment in a laboratory setting, you may experience extreme temperatures through it. This is where a positive displacement pipette can be a suitable way for carrying out a seamless experiment. Along with this, a piston is attached in the pipette which can be useful for pushing out liquid in accurate volumes.

This will keep you away from getting affected by liquids in high temperatures. It would also keep the accuracy in check as there will be significantly less chances of liquid spill over, as the external pressure is involved while pipetting.

For handling more precise measurements, using an **electronic pipette pump** can also enhance accuracy by offering controlled and consistent aspiration and dispensing rates, reducing human error.

Conclusion

Conducting a seamless experiment in a laboratory is serious work, where you may need to keep a check on the environmental factors. As these can affect pipetting standards and also lead to inaccuracies you may want to keep yourself away from.

So, there are multiple ways which can be followed for preventing and controlling the uninvited humidity, temperature fluctuations, or pressure changes. These can be controlled during an experiment which supports you through and provides accuracy, can be seen results.
