Feature of sero pipette​

  • Made of high-quality medical-grade polystyrene (PS), this pipette offers high transparency for easy viewing.
  • A color-coded ring on the neck allows for quick identification of different sizes.
  • A smooth interior minimizes liquid residue and is chemically resistant.
  • Multiple specifications: 1 ml serological pipette, 2 ml serological pipette, 5 ml serological pipette, 10 ml serological pipette, 25 ml serological pipette, 50 ml serological pipette​, 100ml etc. are available to meet different experimental needs.
  • The bidirectional scale is clear and accurate, meeting both sample addition and sample removal needs.
  • Made with a high-quality filter core, it effectively prevents cross-contamination caused by aerosols and backflow resulting from excessive pipetting force.

FAQ of serologic pipette​

How To Use Serological Pipette?

Choose the correct size pipette

  • Select a pipette close to the volume you need (e.g., use a serological pipette 10ml​ for ~7 mL instead of a 25 mL pipette).
  • This improves accuracy and control.

Attach to a pipette controller (never use your mouth!)

  • Insert the upper end of the pipette firmly into a manual or electronic pipette aid.
  • Make sure the connection is airtight.

Pre-wet the pipette (optional but recommended)

  • Aspirate and expel the liquid once before taking your final measurement.
  • This helps improve precision by conditioning the inner wall.

Aspirate the liquid

  • Immerse the tip just below the surface (about 2–5 mm, not deep) to avoid drawing bubbles.
  • Slowly release the controller’s suction to pull the liquid up to the desired mark.
  • Keep the pipette vertical for accurate volume reading at eye level.

Transfer to the receiving container

  • Touch the pipette tip gently to the wall of the vessel to prevent splashing.
  • Dispense by controlling airflow — either by gravity (for complete emptying) or using the controller’s expel function.
  • Some serological pipette tips​ are “blow-out” types (double rings at the top) — expel the final drop using the controller to deliver the full calibrated volume.

Dispose properly

  • Serological pipettes are usually single-use and sterile. Discard in a proper biohazard container.
  • Never leave used pipettes on the bench, as this risks contamination.

1. Understand the two major types of pipette serological

  • TD (To Deliver) — Marked for exact delivery when you allow liquid to drain to zero without forcing the last drop out.

  • Blow-out (double rings at the top) — You must “blow out” the last bit using the pipette controller to deliver the full calibrated volume.

2. Know how the graduations are arranged

  • Standard serological pipetters are graduated from zero at the tip to full capacity at the top (e.g., a 10 mL pipette has marks 0 → 10 as you go up).

  • Reverse-graduated pipettes are marked from full capacity at the tip to zero at the top — these are less common but used for repeated aliquots.

Always check whether the numbers increase or decrease toward the tip before you start measuring.

3. Position your eyes correctly

  • Hold the plastic serological pipettes vertically and keep your eyes level with the meniscus.
  • Read at the bottom of the meniscus (the curved surface of the liquid).

  • Avoid parallax errors by not tilting the pipette.

4. Reading an example

Suppose you have a 10ml serological pipette, graduated in 0.1 mL increments:

  • Aspirate liquid up to the 2.0 mL mark.
  • Deliver until the meniscus reaches the 7.0 mL mark.

  • Volume delivered = 7.0 − 2.0 = 5.0 mL.

5. Special considerations

  • Blow-out pipette (double rings): After draining, use the pipette aid to expel the last drop.
  • Non-blow-out pipette (no rings): Allow to drain by gravity only; do not force out the last drop.

  • Sterile work: If working in a biosafety cabinet, keep the pipette vertical and avoid touching non-sterile surfaces to prevent contamination.
