An apparatus for doping a melt of semiconductor or solar-grade material is provided. The apparatus includes a seed chuck, a seed crystal connected to the seed chuck, and a dopant container connected to the seed chuck. The seed chuck defines a first end of the apparatus, and the seed crystal defines a second end of the apparatus. The seed crystal is configured to initiate crystal growth when placed in contact with the melt. The dopant container is positioned between the first end and the second end of the apparatus, and defines a reservoir for holding dopant therein. The dopant container is configured to dispense liquid dopant into the melt when positioned proximate the melt. The dopant container and the seed crystal are connected to the seed chuck simultaneously.
