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

Enhanced flexibility
