About Fluid Drams

A fluid dram (fl dr, also 'drachm') = 1/8 fl oz ≈ 3.697 mL. Used by apothecaries for precise medicinal compounding; a fluid dram divided into 60 minims. Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.

About Nanoliters

A nanoliter (nL) = 10⁻⁹ L. High-throughput drug screening platforms dispense 1-100 nL per well across 384- or 1,536-well plates. Acoustic liquid handlers (Echo) transfer nL volumes with <10% error CV. A human red blood cell ≈0.09 nL; a typical mammalian cell 1-4 nL. Capillary electrophoresis separates proteins in nL sample plugs. 1 nL = 10⁻⁹ L.
