A slurry dispensing system is disclosed. A peristaltic pump may direct a flow of slurry out of a horizontal mixer to a slurry dispenser. This slurry dispenser may be operated on a programmed manner by a controller to dispense slurry into a container. Both a bypass valve and a dispensing valve of the slurry dispenser may be opened/closed on a programmed basis by the controller to deliver slurry to a container, such as a glass column. Slurry may be intermittently directed into a metering chamber of the slurry dispenser, while the remainder of the slurry being directed into the slurry dispenser may be recirculated back to the horizontal mixer.
