Comparison of pipettes and pipettes-GST pipette automatic production line

　　GST pipette automatic production line equipment manufacturers will talk about the difference between lower pipettes and pipettes this time. Pipettes and pipettes are commonly used laboratory instruments for preparing standards and measuring liquids. However, in some laboratories such as chemistry, this reality is often encountered, that is, there are quite a lot of laboratory or experimental personnel, and the The use of liquid dispensers is skeptical, thinking that pipettes are better than pipettes and cost more! Here is a simple comparison for your reference.

　　Comparison of pipette and pipette:

　　1. In terms of comfort of use, pipettes are better than pipettes. Nowadays, the design of the hand-held pipette has more and more incorporated ergonomic principles, which makes the pipette more convenient to use and more humanized.

　　2. In terms of measurement accuracy, the accuracy of pipettes is much higher than that of pipettes. Today's micro-volume pipettes can measure up to 0.1 microliters, which can completely replace pipettes in demanding experimental activities. In fact, for many demanding experimental activities, the accuracy of the pipette cannot meet the requirements.

　　This mainly comes from two aspects:

　　One: The pipette is generally made of glass, and the thermal conductivity of glass is higher than that of the plastic shell of the pipette, that is to say, the external temperature will be directly transmitted to the liquid in the pipette, resulting in the increase of its volume. Change;

　　Second: the glass tube wall of the pipette itself has a thickness, and the glass cannot completely avoid the refraction of light during the transmission of light in the glass. Therefore, there is a difference between the liquid height observed from the outer surface of the pipette and the actual liquid height. .

　　These two points are designed based on different pipettes, so in terms of comfort and measurement accuracy, pipettes are stronger than pipettes. Pipettes are used a lot and are very familiar with it, which creates this misunderstanding.
