Frequently Asked Questions

Can I use any dispensing tip with any fluid?

Although in theory, any dispensing tip can be used with any fluid, the success of an application often depends upon choosing a tip that addresses certain fluid challenges.

Can I reuse a dispense tip?

Like syringe barrels, precision dispensing tips are designed for single use only. The dimensions make them impossible to fully clean. Any attempted reuse can lead to cross-contamination between like fluids, dissimilar fluids, and even the cleaning material. Worse, particularly in the case of adhesives or high viscosity fluids, the tip could become blocked entirely.

What's the difference between a dispensing tip and a dispensing needle?

The most common style of dispensing tip consists of a steel cannula bonded into a plastic hub. Cannula diameters can range from multiple millimeters to a fraction of a millimeter. Particularly when attached to a syringe barrel, tips with narrower cannulas are reminiscent of needles used for medical injections. However, their ends are not sharp, and they are made for industrial use only. The names may be different but the devices – and their functions – are the same.
