Advantages of the Masterflex® Gravimetric Filling System

The Masterflex Gravimetric Filling System is a new system that consists of a Masterflex peristaltic pump combined with an A&D Apollo series gravimetric dispense bundle. There are 7 balance bundles to choose from. The balance and the pump are connected by a unique A&D controller that enables instant control feedback to ensure dispense accuracy; and all fluid movement is contained within Masterflex pump tubing. The Gravimetric system aims to solve many problems and challenges.

Here are three clear benefits to this gravimetric filling system:

1. Solves the common issues of wastage

This system provides accuracy and repeatability. Every drop is accounted for, and the container never overfills—no product is ever wasted. The balance controls the peristaltic pump and has three modes during the filling process to ensure that no overspill happens. As the Masterflex pump can shift liquid at several different speeds, the balance becomes the master.

2. No more health and safety issues from pouring

Pouring manually carries risk, not just from the loss of product but from damage to the balance. Liquid containment within the tubing gives instant relief and benefit to the semi-automated system. The lateral benefit is the removal of manual involvement, lifting and pouring, which removes health and safety issues when using a semi-automated system. Plus, there is no need to stand by the equipment throughout the process as the gravimetric system manages itself. Not only is there zero manual handling, but the fluids are contained within the tubing.

3. Efficiency and accuracy are improved

The dispense accuracies available with gravimetric dispensing exceed those achievable using the peristaltic pump by itself and reduce the need for tubing calibration. Efficiency is improved along with accuracy by optimizing container throughput in the system when compared to more manual methods.

The Masterflex Gravimetric System can deliver:

  • Semi-automated process
  • Reduce wastage, reduce cost from clean up and product
  • Improve process efficiency
  • Achieve target production
  • Upscaling and scalability

The Masterflex peristaltic pump can accept many different sizes of tubing, depending on the size of the pump head to allow the pump to fill containers more rapidly using higher flow rates. The pump can also be used to scale up production by increasing the pump’s motor capacity with larger-scale pumps available from Masterflex. Balance capacity, Masterflex drive selection, and tubing options allow ample room for customization to meet required fill volumes and allowing chemical compatibility with most liquids.
