Pipette controllers are widely used in various types of laboratories, whether in scientific and research laboratories, diagnostic laboratories or chemical laboratories. Pipette controllers provide repeatable measurements and are used to measure slightly larger volumes than automatic variable-volume pipettes. Pipette controllers are typically made of plastic and use a manual mechanism to draw up and dispense the measured substance.
Pipette controllers need additional components for their correct operation, such as serological pipettes, which enable a correct handling of measured substances.
Application of pipette controllers in the laboratory
Pipette controllers are usually calibrated to allow accurate and repeatable volumetric measurement. One of the most important applications of pipette controllers is the aspiration of samples, which are then subjected to various chemical analyses, both qualitative and quantitative. Pipette controllers allow the exact volume of sample to be drawn up repeatedly within the same range, which is essential in many experiments where the amount taken is crucial.
Pipette controllers are also useful for preparing solutions of a specific concentration, a technique used in many chemistry experiments. In addition, pipette controllers serve as an essential tool for carrying out chemical reactions in small volumes. For reactions that require small amounts of chemical substance, pipette controllers enable precise and accurate addition of the right amount of ingredients. This allows the reaction to be controlled, which is particularly important for reactions that are very sensitive to changes in chemical conditions.
Pipette controllers are also used in molecular biology research, mainly for cell and bacterial cultures, and with the attached serological pipettes, they enable the correct preparation of high-quality microbiological mediaor facilitate the transfer of whole cell colonies. The precision of pipette controllers is especially important for biological samples which are often limited in quantity.
Types of pipette controllers
In scientific laboratories, pipette controllers can be divided into two main types: manual and automatic. Both types have their advantages, and the choice of the right type of a pipette controller should be guided by the specific nature of the tests to be performed and the preferences of the user.
Manual pipette controllers are relatively simple to operate and usually do not require complex calibration. Manual pipette controllers provide relatively accurate volume measurements, and their cost is usually relatively low compared to automatic controllers. Manual pipette controllers, however, require a certain level of skill on the part of the user, as the precision of measurements depends on the correct setting and operation of the controller. It is important to learn and practise correct pipetting technique, which has a direct bearing on the repeatability of measurements. It is important to recognise hand fatigue when handling a pipette controller and to give your hand a rest, as this will reduce the risk of error.
Automatic pipette controllers enable precise and convenient volume measurements. Automatic pipette controllers feature a mechanism to set the desired volume, allowing multiple measurements to be made with less risk of human error. Automatic controllers are also more convenient to use than manual controllers, as they do not require repetitive hand movements, allowing for more comfortable and less tiring work. However, automatic controllers tend to be more expensive than manual controllers and require periodic calibration and maintenance.
There are also semi-automatic controllers that combine the features of manual and automatic controllers. Semi-automatic controllers have a mechanism for setting the desired volume, but require manual pumping or other operations by the user. Semi-automatic controllers are relatively easy to use and allow accurate volumetric measurements in a more convenient way than manual controllers.
