Controlled freezing charges, together with annealing and process familiarity with supercooling outcomes, are frequently utilized to obtain uniform ice crystal distribution. More recent systems can also be giving the chance to nucleate on demand from customers, even more increasing products uniformity across lyophilizer shelves, and is particularly a highlight in foreseeable future lyophilization technology.
