A weighing bottle is a specialized laboratory container designed for accurately measuring and storing solid or liquid samples during gravimetric analysis. Typically made from high-quality, chemically resistant glass, these bottles are ideal for precise weighing as they ensure minimal sample contamination and maintain stability under various conditions. The bottle usually comes with a tightly fitting ground-glass stopper to prevent moisture absorption and sample loss. Available in different sizes, weighing bottles are often used in conjunction with analytical balances for precise measurements, making them essential in research, chemical analysis, and other scientific applications requiring high accuracy.
