Pipettes as one of the laboratory's routine instruments have a great impact on our experimental results, and our pipetting results are very susceptible to pipette usage techniques. In order to get the best results and to ensure the accuracy of the experiment, we need to use good pipetting techniques. Lebe will introduce you to tips and tricks for getting the best pipetting results.

Tip 1 : Constant room temperature
Pipette at constant room temperature. The ideal room temperature for pipetting pipettes is + - 21.5 ° C , which is also suitable for calibration. Why prevent a large or sudden change in temperature and pipetting at a constant room temperature? This is because the air in the pipette does not adapt quickly enough to the temperature difference and the amount of sample may be affected. Pipetting at constant temperature increases accuracy by up to 5% .

Tip 2 : Always store the pipette vertically
Do not place the pipette flat in the drawer or on the work surface, as this may damage the end of the pipette handle and cause a leak. In addition to this, residual liquid can also flow into the shank, contaminating the pipette. Proper storage of the pipette can help us prevent immeasurable errors and protect the instrument.

Food Additives

Food additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.

The advantages of food additives are these followed:

1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
