The Masterflex Gravimetric Filling System is a new system that consists of a Masterflex peristaltic pump combined with an A&D Apollo series balance. There are 37 balances to choose from. Both units are connected by a unique A&D controller that enables communication between the balance and the Masterflex pump, and all fluid movement is contained within Masterflex pump tubing. The Gravimetric system aims to solve many problems and challenges.
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.
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.
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:
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.
