First of all, in terms of the comfort of use, the pipette beats the pipette. Now the handheld pipette, its appearance design, has been more and more mixed with ergonomic principles, making the pipette more convenient to use, and more humanized.

Secondly, in terms of measurement accuracy, the accuracy of the pipette is much higher than that of the pipette. Now the small volume pipette has been able to measure to 0.1 micro upgrade, fully instead of the pipette to engage in strict experimental activities. In fact, for many more demanding experimental activities, the accuracy of the pipette is inadequate.

This mainly comes from two aspects. First, the pipette is generally made of glass, and the thermal conductivity of the glass is higher than 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 change of its volume;

Second, because there is a thickness in the glass wall of the pipette itself, and the glass cannot completely avoid the refraction of the light in the glass, the liquid height observed from the outer surface of the pipette is different from the actual liquid height. These two points are almost completely avoided because of the different designs of the pipette.

Thirdly, the technical requirements of the pipette for the users are far lower than those of the pipette for the users. Accuracy of the pipettes. Including accuracy, the requirements of the users are not high, as long as you master the basic operation techniques, even inexperienced operators can also do accurate measurements. But the pipette is not good, and the experienced personnel and not experienced personnel operation result error is larger.

In contrast, using pipettes is far more efficient than using pipettes, especially with the advent of multichannel and electronic pipettes.

Of course, the pipette brings so many benefits at the same time, but there are also shortcomings, for example, its price is higher than the pipette, therefore, for specific experimental activities, should be according to the experimental time, requirements according the selection, but in general, the pipette has fully had the ability to replace the pipette!

Through the above comparison, which is more accurate about the pipette and pipette (gun)? Do you have an answer in your mind? The pipette and the pipette can be said to have their own advantages. For example, the pipette can only take a single volume, and the volume of the pipette gun can be changed as needed; Generally, when the suction volume is less than 1mL, use a pipette gun, and use a pipette for others; The slender neck of the pipette can go deep into the volumetric flask, while the pipette gun sometimes can't do anything, and so on. How to choose depends on your own needs. Whether it is the verification of the pipette or the calibration of the pipette gun, it is primary and cannot be ignored, because it is closely related to the subsequent analysis results.
