look at the number!
Use a pipette or even a micro-pipette.
No , you cannot use it . It will probably cause brain haemorrage and kill you .
To properly read a pipette, first ensure it is clean and calibrated. Hold it vertically, draw up the liquid to the desired volume, and then read the meniscus at eye level. Make sure to account for any calibration markings on the pipette.
This is my answer, but I myself don't think it is the shortest way! :( First u take 100 micro liters, from the water drips down, u will get 45 mcl!Do it twice u will get 90 mcl !Then use the pipette with that 90mcl u will get 35 mcl ( 90 - 55 = 35). Do it 3 times more. One 35 mcl u will add 45 mcl (easily get it by 100 - 55 = 45 mcl) u will get 25 mcl (80 - 55=25 mcl). With another 35 mcl, do the same thing and u will get another 25 mcl. Add the 35 mcl left with another 2 25mcl u will get 85 mcl. And thet let use the pipette again and u will get 30 mcl as u wish (maybe it will take long time but it 's still bettter than having no solution ) :))! Thx for reading!
To properly read a serological pipette for accurate measurements, follow these steps: Hold the pipette vertically and at eye level. Check the calibration marks on the pipette to ensure it is the correct volume. Align the meniscus (the curved surface of the liquid) with the desired calibration mark. Read the volume at the bottom of the meniscus for an accurate measurement. Make sure to account for any liquid clinging to the walls of the pipette. By following these steps, you can ensure precise and accurate measurements when using a serological pipette.
For the majority of pipettes the last drop should be left in the pipette; read the recommendation from the pipettes catalog.
A micropipette will draw up very small amounts, much smaller than a normal one will
A graduated cylinder is appropriate for "normal" quantities. You may need a micro pipette for very small quantities.
Some precautions when using a pipette include always keeping it clean and properly maintained, avoiding contact of the pipette tip with skin or other substances to prevent contamination, and ensuring proper calibration and technique to ensure accurate measurements. Additionally, always follow the manufacturer's instructions and handle the pipette with care to prevent damage.
No
The instrument that holds the pipette is called a pipette bulb or a pipette filler. It is used to create suction for drawing liquid into the pipette and controlling its release.
Another name for Pasteur pipette is transfer pipette.
