Sampling precision & repeatability

Sampling precision and repeatability are affected by the geometry and the surface of the pipetting tips...

Tapered tips are designed according to the sampling volumes; Minitubes has developed a proprietary process to obtain very smooth ID surfaces on the cylindrical portions and on the transition cones, with no limitation on the stepped lengths.

Sampling repeatability is linked with the tip manufacturing process variability;

Tip geometry and surface properties affect the sample / pipette contact surface and may influence droplet formation.
