Shipping Dewar Spacer, Canister & Support Ring for Cassettes

The dewar canister fits SSRL cassettes replacing the stock canister in dry shipping dewars. The styrofoam spacer is used to keep the cassette in place when shipping a single cassette inside a dry-shipping dewar. The canister support ring is inserted inside your shipping dewar to support the canister if the handle starts to bend under the weight of the cassette.
