Pipettes are one of the routine laboratory instruments, and the pipetting results are actually very susceptible to our use of 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 continue to introduce you to two tips for getting the best pipetting results.
Tip 1: Tip into the water depth
The correct tip entry depth is especially important for micropipettes. The depth of the tip of the tip will affect our actual pipetting. If the tip is too deep into the water, the amount of liquid will increase as the pressure increases. The liquid remaining on the surface of the tip can affect the result. If the tip is not too deep, it will cause air to enter, creating bubbles and inaccurate capacity. The correct depth of entry increases accuracy by up to 5%.
Pipette capacity | Water depth |
2 and 10ul | 1mm |
20 and 100ul | 2-3mm |
200 and 1000ul | 3-6mm |
5000ul and 10ML | 6-10mm |
Tip 2: Dispensing Techniques <br> For most applications, Lebe recommends placing the end of the tip against the wall of the container during dispensing. This can reduce or eliminate the sample remaining on the tip after dispensing. The tip of the tip is then slid upward along the side wall to remove the pipette, thereby removing any residual droplets at the tip hole. This pipetting technique increases the pipetting result accuracy by up to 1%.
Another technique is to dispense liquid directly onto the surface of the liquid. Thin wall tips are recommended for this technique because thin wall tips allow for adequate drainage.
If it is directly dispensed into the liquid, Lebe recommends using a pipette like the IKA pipette that can be used for reverse mode pipetting for reverse pipetting to prevent pipetting after dispensing.
[Wolfberry" and [goji berry" are synonyms for one of the best-known and admired berries from China, called gou qi or kei tze in Chinese.
The specifications of Dried Goji Berry are distinguished by the number of grains per 50g. The smaller the number of grains per 50g, the larger the grains of each Dried Wolfberry fruit. Generally, the wolfberry with 180 grains per 50g is the least on the market and the most popular.
Goji berries (also known as Wolfberries, Lycium barbarum), have been used in Asian herbal medicine for over 5,000 years and has been regarded as one of the most nutrient-rich foods on earth.
