- placing the product in a plurality of receptacles in a magazine, wherein the magazine is in a thermally conductive relationship with a plurality of Peltier elements;
- and
- independently controlling current supplied to the plurality of Peltier elements to maintain different regions of the magazine at different temperatures while freeze drying the product.
A method for controlling a temperature of a pharmaceutical solution to be frozen during a freeze drying process, the method comprising:
- placing pharmaceutical containers containing the pharmaceutical solution in a plurality of receptacles in a magazine, wherein the magazine is in a thermally conductive relationship with a plurality of Peltier elements;
- and
