In order to accurately control the flow rate or volume delivery of the pump, the PHD ULTRA
™
requires that
each method include accurate setting of the syringe diameter and volume. All Methods (Quick Start,
Preloaded, User-Defined) require a syringe definition, either by selecting from the installed syringe
specifications list or by defining a new (Custom) syringe in the application.
The built-in syringe specifications list provides a convenient lookup function that allows users to select
from a wide variety of syringes from major manufacturers, including: Air-Tite, Becton Dickinson, Hamilton,
Harvard Apparatus, Cadence Science, SGE Scientific Glass Engineering, Sherwood – Monoject, and Terumo.
This Guide also includes a reference table of major syringe diameter and volume parameters in Appendix A:
Syringe Volume/Diameter Reference Table.
The following parameters must be set for every syringe selection:
• Syringe Diameter: mm
• Syringe Volume: ml or µl
TO SELECT A SYRINGE USING THE SYRINGE LOOKUP FUNCTION:
1. From the Quick Start or Method Main screen, choose the Syringe Select button.

WARNING: When using low-volume, small diameter syringes or pumping
high-viscosity liquids, you should adjust the Force value in the Settings
menu to avoid accidental damage to the syringe.
