druppelpipet

A druppelpipet, also known as a dropper or Pasteur pipette, is a common laboratory tool used to transfer small volumes of liquid. It typically consists of a glass or plastic tube with a narrow opening at one end and a rubber or plastic bulb at the other. The bulb is squeezed to create suction, which draws liquid into the tube. Releasing the bulb then gently expels the liquid.

Druppelpipetten come in various sizes and shapes, with some designed for precise measurements and others for general transfer. The accuracy of the volume dispensed can vary significantly depending on the type of druppelpipet. Graduated druppelpipetten have markings along the tube to indicate specific volumes, allowing for more controlled dispensing. Non-graduated druppelpipetten are generally used for qualitative transfer where precise volume is not critical.

These pipettes are widely used in chemistry, biology, medicine, and various industrial applications. They are often employed for adding reagents, taking samples, or dispensing medications. Due to their simple design and ease of use, druppelpipetten are a fundamental piece of equipment in many scientific and medical settings. For hygiene and to prevent cross-contamination, single-use disposable druppelpipetten are also common, particularly in medical and research environments. Cleaning and proper handling are important to ensure the integrity of experiments and the safety of users.
