Aldrich is well known among research chemists for having a wide selection of products. Their trademark "Sure-Seal" bottle, which incorporates a PTFE-lined septum inside a crown cap, allows the contents to be easily dispensed under an atmosphere of inert gas. Also, the Aldrich "Atmos Bag", is a sealable glove bag which enables the user to handle materials that are air and moisture sensitive in an inert atmosphere, such as nitrogen.
