1. The Micropipette developed by Heinrich Schnitger, which is often referred to as " Eppendorf pipette " in laboratory usage, counts today in various designs as standard almost every biomedical laboratories.
2. For instance, the cannulation of a single microvessel with a micropipette, the microvessel is perfused with a certain pressure, occluded downstream and then the velocity of some cells will be related to the permeability.
3. To treat male infertility, a micropipette sucks as few as 100 sperm from a man's ejaculate and shoots a single one into the egg, which is then put into the womb or fallopian tubes.
4. The third problem, that of obtaining electrodes small enough to record voltages within a single axon without perturbing it, was solved in 1949 with the invention of the glass micropipette electrode, which was quickly adopted by other researchers.
5. To administer the test, a police officer simply has to break a seal on a tiny micropipette of chemicals, and insert a particle of the suspected substance; if the chemicals turn purple, this indicates the possibility of marijuana.

9. With this technique, a microelectrode was placed inside the motor endplate of the muscle fiber, and a micropipette filled with acetylcholine ( ACh ) is placed directly in front of the endplate in the synaptic cleft . A positive voltage was applied to the tip of the micropipette, which caused a burst of positively charged ACh molecules to be released from the pipette.
