Anaesthetic Key Filler
The key filler is designed to be used exclusively with key fill vaporizers. This is an agent specific adapter that prevents the inadvertent mixing of agents.


For easy access and use of the Vaporizer in combination with the UNO vaporizers, we have designed a table stand. If you order a vaporizer, flowmeter and stand, we will supply these to you mounted.
