Oldatok

Oldatok is the plural form of the Hungarian term oldat, which denotes a homogeneous liquid produced by dissolving a substance in a solvent. In scientific usage, oldatok can refer to any solution prepared for experimental or practical purposes, and they are commonly described by their concentration and solvent.

In chemistry and analytical contexts, oldat describes a solution with a precisely defined composition. Typical examples include saline oldat or acid and base solutions used in titrations, spectroscopy, and calibration. Concentration is expressed in units such as molarity, molality, normality, or percent mass/volume, and careful labeling and storage are required to maintain stability and accuracy.

In pharmacy, botany, and related fields, oldat also denotes botanical or chemical extracts prepared by solvent extraction. These oldatok may be water-based (vizes oldat) or solvent-based such as alcohol-based (alkoholos oldat). Preparation methods include infusion, decoction, maceration, and percolation, using solvents like water, ethanol, methanol, or acetone. Such extracts are used for medicinal preparations, research, or as intermediates in further processing.

Quality control and safety considerations apply to oldatok, including accurate preparation, appropriate storage conditions (protecting sensitive compounds from light or heat when needed), labeling, and proper disposal. The term is primarily used in Hungarian scientific and educational contexts, where it represents both standard solutions for measurement and plant or chemical extracts prepared for analysis or formulation.
