Problems addressed: Wicking (adhesion of liquid to OD of dispensing tip), drops hanging on tip Contraindications: N/A, aside from lack of necessity Description: Teflon coating solves issues with liquids that adhere to the OD or end of the dispensing tip.
After multiple dispenses, the accumulated
globule of liquid breaks off and can throw
off volumes or land on machinery or
containers. By ensuring that no product
remains at the tip after each dispense, this
issue is avoided.
