The SP VirTis Freezemobile 25L is a research freeze dryer in a compact, freestanding, mobile design. It includes the microprocessor-based Sentry 2.0 controller, and its strength is manifold flexibility — which makes it well suited to research where samples sit in round-bottom flasks of varying size and the number of flasks changes from run to run.
