About these units
Microliter (µL)
A microliter is 10⁻⁶ liters, a standard unit in laboratories worldwide. It is indispensable in pipetting, sample preparation, PCR reactions, enzyme tests, and pharmaceutical formulation. Most laboratory pipettes are designed with microliter precision, and many experiments rely heavily on the ability to dose volumes like 10 µL or 100 µL with high accuracy. Its use outside laboratories includes medical diagnostics, such as blood sampling, allergy testing, and microdose vaccine research. The microliter is an essential unit linking biological processes to controlled experimental conditions.
Dram (dr)
The fluid dram is a small historical unit equal to 1/8 of a US fluid ounce or 3.6967 mL (US), with slightly different imperial values. It originated in apothecaries and early pharmaceutical texts, where drams measured potent liquid medicines, tinctures, and extracts. In daily life, drams appeared in old cocktail recipes, medicinal syrups, and household remedies. However, the inconsistency between US and UK drams, along with the rise of the metric system, pushed it out of modern use. Today, the dram survives mostly in whiskey culture—where a "dram" informally means a small pour, not a precise measurement—and in historical studies of medicine.
