Siirtopipettejä

Siirtopipettejä, known in English as transfer pipettes or Pasteur pipettes, are simple laboratory tools used to transfer small amounts of liquids. They are typically made of flexible plastic and feature a hollow tube with a bulb at one end. The bulb acts as a simple pump, allowing the user to draw liquid into the tube by squeezing the bulb before use and then releasing it to aspirate the liquid. A gentle squeeze on the bulb then expels the liquid.

These pipettes are disposable, making them convenient for single-use applications and reducing the risk of cross-contamination. They are not designed for highly accurate measurements, as their volume capacity is often not precisely calibrated and dispensing can be less precise than with volumetric or graduated pipettes. However, their ease of use and low cost make them ideal for general-purpose liquid transfer in various settings, including educational laboratories, basic research, and certain industrial applications.

Siirtopipettejä come in different sizes, with varying tip diameters, to accommodate different liquid volumes and viscosity. They are commonly used for transferring reagents, samples, or small volumes of solutions where precise volumetric accuracy is not critical. Their simple design and affordability have made them a staple in many scientific and educational environments.
