Probenschalen

Probenschalen, also known as sample dishes or weighing dishes, are laboratory consumables used to hold, transfer, or weigh small quantities of solid or liquid samples. They are typically made of materials that are inert and resistant to chemicals commonly found in laboratory settings, such as glass, plastic, or aluminum. The design of probenschalen varies depending on their intended application. Some are shallow and broad, facilitating easy access for scooping or scraping samples. Others may have a conical or V-shaped bottom to aid in the complete transfer of contents.

Commonly, probenschalen are used in analytical chemistry, where precise weighing of substances is crucial for determining concentrations or yields. They can also be employed in sample preparation for various analytical techniques, such as chromatography or spectroscopy. In biological laboratories, they might be used for handling cell cultures or reagents. The disposable nature of many plastic probenschalen reduces the risk of cross-contamination and simplifies laboratory workflows. Reusable glass or metal probenschalen require thorough cleaning and drying between uses to maintain accuracy and prevent contamination. The choice of material and design for a probenschale depends on factors such as the type of sample, the required precision, temperature considerations, and the need for reusability.
