How Peristaltic Filling Machines Work

How Peristaltic Filling Machines Work

The peristaltic pump makes intermittent contact on only the outside of the surgical (product) tubing so that the product only touches the inside of the tubing. The filler’s master computer independently tracks the # of rotations of the peristaltic pump head so that it knows precisely how much product has been delivered. When the target fill volume is reached, the pump stops and the remaining product fluid does not drip out due to pipette action. The computer stores all fill parameters in memory for fast changeovers.

Application:

Specifically designed for high value, small volume fills at very high accuracy. Suitable for aqueous and other light viscosity products.

Examples

Pharmaceutical preparations, fragrances, essential oils, reagents, inks, dyes, and specialty chemicals.

Advantages

Fluid path is disposable; easy cleanup and elimination of cross contamination problems. Accuracies of 0.5% are achievable for fill volumes less than 1 ml.
