New roller assembly now ships with A4 and M4 peristaltic pumps!
We are simplifying tube replacement with our new and improved A4 and M4 roller assemblies.
Benefits Include
Lower cost of ownership
Rollers can be replaced individually, eliminating the need to purchase an entire roller assembly.
Ease of maintenance
New roller assembly design allows for safer and easier tube replacement without a tube installation tool.
Enhanced flexibility
Switch to different tube models by
changing the squeeze rollers, not the
entire roller assembly.
