The Vapofil and AntiSpil devices allow for safe storage and transfer of anesthetic agent from bottle to vaporizer. They are color coded and have a keyed cap that fit only the corresponding anesthetic bottle for popular anesthetic agents. The Vapofil has a color coded keyed block end on a flexible transfer tube for use with key fill vaporizers. The transfer tube allows for simultaneous air and agent flow for rapid filling with no air-locks or drips. The AntiSpil’s pour spout ensures that the transfer of anesthetic agent goes into a funnel fill vaporizer with no drips or spills. Its metered valve controls the agent’s rate of flow reducing the chance of overflow at the funnel port. Both versions have an anti-pollution plug to prevent unwanted spillage or waste during storage.
