When it comes to handling liquids the results do not depend on the pipette or the tip alone, but the combination of them both. Tips function according to the positive-displacement principle, ensuring that the correct volume is dispensed with regard to the density and viscosity of the liquid used. The positive displacement system provides safer dispensing of radioactive and toxic substances as well as solutions with high vapor pressure.
It is important that you do not underestimate the use of a tip when it comes to performing tests with pipettes. Tips are the critical link in ensuring that the correct volume of liquid is aspirated and dispensed and that the liquid is not contaminated in the process.
