Bluelab Cassette replacement for pH Controller or M3/M4 Peripod Pumps

Quick Cassette Swaps for pH Controllers and M-Series, 10–120 ml

When a peristaltic cassette wears, doses shrink and pH or nutrient control becomes less precise. This replacement cassette puts the rollers and internal tubing in one unit. Unscrew the pump cover, twist the old cassette off the drive motor and fit the new one.

It is a small, inexpensive part that keeps controllers and dosers accurate, so both home and commercial users often keep one in stock.
