Teflon Coated Filler Needles

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.
