How does a pipette filler work?
Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid.
It is a piece of glassware used in titration to accurately measure a certain volume of liquid (e.g. 25cm3 ). It's a long tube with a bulb in the middle and at the top has a mark to show when the e.g. 25cm3 volume is reached. It is attached to what is called a "pipette filler" which allows the liquid to be sucked into the bulb pipette.
A pipette bulb is the rounded part of a pipette which you squeeze the air out of, then release to draw liquid into the pipette. If you are using a calibrated glass pipette, it will be a separate piece made of rubber which is fitted to the pipette. If it is a simple plastic pipette then the bulb will be made of the same semi-transparent plastic, and the pipette will all be one piece.
The difference between the two is that the RBC Diluting pipette counts the erythrocytes (Red blood cells) while the other one counts the leukocytes (White blood cells) and that the pipette (RBC) itself has a more circular body compared to WBC diluting pipete. On the other hand, WBC diluting pipette has a pointed tip unlike the RBC Diluting pipette. -Fer Philippines <3
