Liquid Handling is a fundamental task in any laboratory, involving the transfer of precise volumes of liquid from one container to another. This task is carried out manually, semi-automated, or automated, depending on the complexity and the number of samples being processed.

Manual liquid handling involves the use of pipettes, serological pipettes, and micropipettes. Pipettes are graduated tubes with a bulb at one end that are used to measure and transfer liquid accurately. The liquid is drawn up into the pipette using suction and is then dispensed by releasing the suction. Pipettes come in various sizes and shapes, and the appropriate pipette is chosen based on the volume of the liquid that needs to be transferred.

Semi-automated liquid handling involves the use of electronic pipettes(https://accumaximum.com/products/electronic-pipette/), which are battery-operated and can dispense precise volumes of liquid automatically. These pipettes can be programmed to dispense a specific volume of liquid and can also be used to dispense multiple volumes. Electronic pipettes are particularly useful when working with multiple ...

Automated liquid handling involves the use of liquid-handling robots, which are machines that can transfer precise volumes of liquid from one container to another automatically. These robots are particularly useful when working with large volumes of samples, as they can transfer liquid from one sample to another quickly and accurately. Liquid handling robots can also be programmed to dispense specific volumes of liquid, making them particularly useful in high-throughput screening applications.

Accuracy
One of the key considerations in liquid handling is accuracy. Accurate liquid handling is essential to ensure the reliability of the experimental data. The accuracy of liquid handling is influenced by a variety of factors, including the quality of the pipettes, the technique used to pipette the liquid, and the environmental conditions in the laboratory.

To ensure accurate liquid handling, it is important to use high-quality pipettes and to calibrate them regularly. Pipettes should also be handled carefully, as rough handling can cause them to become inaccurate. The technique used to pipette the liquid is also critical, and the operator should be trained to use the pipettes correctly. Finally, environmental conditions, such as temperature and humidity, can affect the accuracy of the liquid handling and it is essential to keep the laboratory environment stable.

Precision
Another consideration in liquid handling is precision. Precision refers to the reproducibility of the liquid-handling task. Precise liquid handling is essential to ensure the reproducibility of the experimental data. The precision of liquid handling is influenced by the same factors that affect accuracy, including the quality of the pipettes, the technique used to pipette the liquid, and the environmental conditions in the laboratory.

Sample Contamination
In addition to accuracy and precision, another key consideration in liquid handling is sample contamination. Sample contamination can occur when the liquid being transferred comes into contact with other substances, such as dirt, dust, or other samples. Sample contamination can lead to inaccurate and unreliable experimental results, and it is essential to take steps to minimize the risk of contamination.

Choice of Liquid
Another consideration in liquid handling is the choice of liquid. Different liquids have different physical and chemical properties, such as viscosity and surface tension, which can affect the accuracy and precision of liquid handling. For example, highly viscous liquids may be difficult to pipette accurately, while liquids with high surface tension may form air bubbles, which can lead to imprecise liquid handling.

To ensure accurate & precise liquid handling it is important to understand the properties of the liquid being transferred and to choose the appropriate pipette for the task. For example, pipettes with wide-bore tips may be more appropriate for highly viscous liquids, while pipettes with fine-bore tips may be more appropriate for liquids with high surface tension.

Finally, it is important to choose the appropriate volume of liquid for the task. Choosing the appropriate volume of liquid is essential to ensure accurate and precise liquid handling. Using too small a volume may lead to errors, while using too large a volume may lead to waste.

When considering liquid handling systems for a laboratory, it is important to assess the desired level of automation. While a manual device may be suitable for some applications, investing in semi- or fully automated systems can save on reagents and operator hours in the long-term. It is also important to assess the level of throughput and the required speed, precision, accuracy, and volume of liquid handling. The software should also be user-friendly and versatile. Additionally, considering the system’s upgradeability is crucial for future requirements. Finally, it is essential to ensure that the system fits within the lab’s available space, and some manufacturers offer systems with a more compact footprint for laboratories with limited space. Good ergonomic design is also a critical consideration for manual devices.
