Cassette vaporizers: These are pre-filled with isoflurane and come in disposable or reusable cassettes. They are simple to use but may be more expensive than other types.Temperature-compensated vaporizers: These automatically adjust the concentration of isoflurane delivered based on changes in temperature and flow rate. They are more accurate and reliable than cassette vaporizers but also more expensive.Flow-over vaporizers: These use a stream of gas to carry isoflurane from a liquid reservoir to the patient. They are less common than other types of vaporizers but can be useful for delivering very low concentrations of isoflurane.
