Freeze Dryer Sample Containers

Fast-Freeze Flasks. Select your flasks based on your sample sizes. Flasks should be filled to no more than one-third of their volume. Each Fast-Freeze Flask includes a rubber top, glass bottom and a supply of filter paper. Amber-colored glass helps to protect light sensitive samples. Tops, bottoms and filter paper are available to purchase separately as replacement components. Adapters are required which are not included, to attach flasks to freeze dry valve ports.
