Operating Modes

Manual Fixed-Volume Dispensing: Set target volume (mL) and manually control aspiration and dispensing triggers.
Automatic Fixed-Volume Dispensing: Set interval time, volume, and repetition count; single trigger starts automated repetitive dispensing.
Automatic Multi-Step Dispensing: Program up to 10 sequential steps with different volumes and interval times in one filling cycle.
Manual Free Dispensing: Freely control aspiration and dispense volumes via live touch triggers.
Custom Dispensing Programs: Define custom multi-step sequences, speeds, and volumes; save to memory for routine laboratory use.
Titration Function: Perform manual or continuous titration with real-time volume display for preparation of volumetric flasks and pH adjustment.
