Specs & features.
The RBC pipette serves as a dual-function volumetric dispenser and mixing device. Blood is drawn to a specific volume and then diluted with an isotonic reagent (such as Hayem's Fluid or Gower's solution) to prevent cells from rupturing or clumping during the count.

- Red Mixing Bead: A specialized red glass bead sits inside the mixing bulb. It ensures that the blood and the diluting fluid are perfectly homogenized.
- Precision Markings: The stem has graduation marks typically at 0.5 and 1.0. The mark above the bulb is 101.
- Standard Dilution Ratio: When blood is drawn to the 0.5 mark and diluted up to the 101 mark, it yields a precise dilution proportion of 1:200. (If drawn to the 1.0 mark, the dilution is 1:100).
