Features and How to Use Pasteur Pipettes

Pasteur pipettes are made from selected medical-grade LDPE raw materials and are suitable for small-volume pipetting. Optimized surface tension for more fluid flow and easier handling. Here are some introductions of Pasteur Pipettes.

What is a Pasteur pipette:

It is a glass tube with two open ends (usually about 5 mm inside diameter). The tube is thinner at one end and has a smaller inner diameter (less than 1mm and a glue tip at the other end). It is mainly for non-steady-state transfer of liquids, however, often “corrected” by calculating the number of droplets transferred per ml of fluorine, e.g. the ratio of droplets/mL is about Q.U2 ml/decreased.

How to use pasteur pipette:

Pasteur pipette uses by inserting the docking end of Pasteur pipettes with a cotton plug before use and then sterilizing the pipettes so plugged, that the transferred liquid can avoid microbial contamination. In microbiology research, graduated tampons can also block (analytical) pipettes for the same reason.


  1. Good transparency, with tick marks, easy to observe;
  2. It has certain elasticity and plasticity and should bend at a certain angle, which is conducive to entering the micro-container for liquid extraction or liquid addition;
  3. Good elasticity, not easy to break, suitable for quick pipetting. Easy to use, accurate and reliable, good repeatability of drop volume;
  4. Disposable Pasteur pipette ends are heat sealable for conveying small quantities of liquids;
  5. Lightweight, compact structure, easy to use, low consumption of consumables, one-time reduction of raw material pollution during use;
  6. Smooth and transparent, reducing liquid adhesion, good elasticity, easy pipetting, accurate scale;
  7. Small tips ensure repeatability of drops; tube ends can be heat-sealed to easily carry liquids;
  8. The infusion tube body is translucent and bright white, with the ideal liquid flow on the tube wall and strong controllability;
  9. Disposable sterile straws are slender, flexible, and bendable for easy access to micro or special containers;
  10. Often used for operations such as absorbing, transferring, or carrying small amounts of liquids;
  11. The tube body is translucent and bright white, the wall fluidity is ideal, and the controllability is strong;
  12. The tube body is slender and soft, bendable, and easy to enter and exit traces or special containers;
  13.  Sterilization method: ethylene oxide EO disinfection and sterilization.

Notice about Pasteur Pipettes:

  • In addition to the cost, various conditions should be considered when using plastic as a reaction vessel, similar to heating and refluxing strong corrosive solvents, whether the plastic can accommodate it
  • And should affect the process no matter if there are residual additives, then it will dissolve in the solvent, etc.
