Syringe Pump Program Composer

Understanding PPL Format

PPL files use a simple phase-based structure:

• PHNxx — Phase number (01-99)
• FUNRAT — Rate function (infuse/withdraw)
• FUNPAS — Pause function
• FUNLOP — Loop function
• DIRINF/DIRWDR — Direction
• RATx.xxUM — Rate with unit suffix
• VOLx.xxxUL — Volume with unit suffix

Syringe Pump Best Practices

• Prime the syringe before running programs to remove air bubbles
• Start with low rates and ramp up to avoid sudden pressure spikes
• Add pause steps between direction changes to let pressure equilibrate
• Use loops for repetitive protocols instead of duplicating steps
• Verify rate limits — smaller syringes have lower max rates
