This filler is the machine of choice for high value, small volume fills at very high accuracy. It is primarily suitable for aqueous and other light viscosity products. Examples of products filled on this machine are sterile and pharmaceutical preparations, fragrances, essential oils, reagents, inks, dyes, and specialty chemicals. The unique advantage of this machine is that the only fluid path is surgical tubing. The fluid path is disposable; easy to cleanup and eliminates cross contamination problems. Accuracies of 0.5% are achievable for fill volumes less than 1 ml.
The peristaltic pumps on this bottle filler make intermittent contact on only the outside of the surgical (product) tubing so that the product only touches the inside of the tubing. Like the servo pump bottle filler above, this system operates with servo drives. Each servo drive is dedicated to one or two peristaltic pump heads. 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 of the surgical tubing.
