Direct Displacement type Stepper/ Repetitive Pipette is ideal for routine or research applications in diagnostics, molecular biology and environmental analysis. The Stepper/ Repetitive Pipette works on the direct displacement principle. The Stepper/ Repetitive Pipette offers high precision dispensing of liquid media with high viscosity, high density, or high vapour pressure. Direct Displacement type Stepper/ Repetitive Pipette performs contamination-free operation, since no aerosols are formed.
