Gloveboxes and isolators are used to contain hazardous substances or materials that must not come in contact with the outside environment. Gloveboxes and isolators are used for both protecting personnel & protecting the isolator product by maintaining secure containment fields. These fields are necessary for handling hazardous material including radioactive or toxic compounds. Gloveboxes and isolators are typically airtight containers that can also provide sterile environments that are oxygen-controlled & moisture-controlled. They have specially-sealed ports that are fitted with gloves allowing operators to manipulate the objects and substances inside the isolator. The glove ports can come in round or oval shapes and are fitted with cuff rings to seal the port from the outside environment. Gloveboxes and isolators can also come with iris ports, which are self-sealing silicone ports that seal tightly around the operator's bare hands & arms. These ports enable operators to work with small or delicate materials that are difficult to handle with gloves.
