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 Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.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 Picoliters
A picoliter (pL) = 10⁻¹² L = one cubic micrometre. Inkjet printers deposit 1-10 pL droplets per dot to achieve >600 DPI. Droplet microfluidics uses pL-sized reaction chambers for digital PCR and single-cell analysis, detecting a single DNA molecule per droplet. High-throughput drug-screening robots dispense compounds in pL volumes into 1,536-well plates. 1 pL = 10⁻¹² L.
