The pump head is where tubing is compressed by rollers, and choosing the right one is critical. Consider:

• Number of rollers (affects pulsation and tubing life).
• Number of channels (single-channel vs. multi-channel for simultaneous pumping).
• Tubing compatibility (size, material, and wall thickness).
• Ease of tubing change (quick-loading heads save operator time).
• Flow rate range (large heads support higher flow, compact heads support microflows).
