Mohr Measuring Pipette

Description
The 19th-century German pharmacist Karl Friedrich Mohr developed calibrated pipettes for adding specific amounts of one liquid to another. The Fisher Scientific Company sold Mohr pipettes like this one for routine or educational work, as its catalog number 13-665. From the mid-1960s, they were sold under the FISHER-brand label, as this example was. It is a style K, having a capacity of 5 milliliters, divided to 1/10 of a milliliter and calibrated at a temperature of 20 degrees centigrade.
Fisher also sold a range of pipettes manufactured by other firms such as the Kimble Glass Company and Corning Glass Company. Mohr pipettes were among the goods that could be purchased for high school chemistry and biology classes in the late 1950s and 1960s with matching funds from the U.S. government.
