Abstract

Currently no pipette tips exist which aim to create a full-cone, uniform spray. The spreading of liquid after ejection from a multipurpose pipette tip was analyzed. A computer model was developed to simulate the current-multipurpose pipette tip and analyze internal forces. Results showed that surface tension is the primary fluid property for the formation of a spray. The use of an internal interference mechanism or Venturi effect is proposed to break apart surface tension and create a spray effect.
