With the 18V InstantVap, you can easily perform the oxalic acid treatment with this vaporizer! Preparation only takes a few minutes, and the InstantVap is ready for work with a heated furnace in 3,5 minutes! No more messing with aggregators, inverters and fussing with long cables! No overheating, no waiting for it to cool down, or to heat up! The unit sits firmly in the hole, or at the enterance, no need to hold it while vaporizing! The small teeth on the front of the machine grip into the hive wall, so it can’t tip sideways. Also worth mentioning the easily adjustable accurate, fast oxalic dispenser, the voltage indicator to protect the battery and the strong and easy to clean brass outlet pipe!
