Fluorescein Sodium Salt (C.I. 45350) Extra Pure 25 gram

Fluorescein is an organic dye that is frequently used in various applications, including medicine, biology and industrial research. It is known for its fluorescent properties, which means that the light can absorb and then radiate again in a different wavelength. In medicine, fluorescein is often used as a dye for diagnosing eye problems. For example, it is used to assess the tear film and to detect the presence of damage to the cornea. By dripping a small amount of fluorescein in the patient's eyes, the doctor can follow the dye using a special blue lamp. As a result, any deviations or damage to the eye surface can be identified. In addition, fluorescein is also used in biology for marking and visualizing different structures and processes. For example, it can be used to detect the presence of certain proteins or molecules in cells. By linking fluorescein to a specific antibody or another molecule that binds to the target, it can easily be visualized under a fluorescence microscope. In the industry, fluorescein is used as a dye for different applications, such as coloring textiles, paper and plastic. It is also used as a tracer in water and air flow investigations, where it helps to identify leaks or follow the flow of liquids or gases. Although fluorescein is generally considered safe, there are some precautions that must be taken when it applies. It is important to wear protective gloves and safety glasses to prevent direct contact with the skin and eyes. If contact nevertheless occurs, rinse with water thoroughly. It is also recommended to use fluorescein in a well -ventilated space to prevent inhalation of vapors. Moreover, fluorescein must be stored safely. It must be stored in a well -sealed container, away from direct sunlight and heat sources. It is also important to keep other chemicals separate to prevent possible reactions. In short, fluorescein is a versatile dye that is used in various applications, ranging from medical diagnosis to industrial applications. It offers a valuable tool for visualizing and marking different structures and processes. However, when handling fluorescein, it is important to take the correct safety measures to minimize possible risks.
