Document Summary

Works by changing the value of a unit (ex: mass, volume, length) by a factor of 10 allowing easy conversion using decimal places. Measuring liquids pipettes: graduated cylinders are used to measure milliliters to liters of liquids, pipette: used to measure microliters of liquids, pipetmen p-20, p-200 and p-1000: P-1000 for dispensing 200-1000 l the number on the top of the pipette is the maximum volume of liquid in microliters that the pipette can dispense. When using a pipette, the plunger is pressed all the way down to the second stop to push out any remaining fluid from the tip. Originated in the late 1600"s through robert hooke and anton van leeuwenhoek. In 1665, hooke published a description of a compound microscope (compound: having more than one lens) Over 50 drawings of objects observed using it. Leeuwenhoek ground lenses as a hobby and developed single lens microscopes.
