Custom short-path head designed to minimize bumping colored impurities from contaminating clear distillate. There is a rugged Vigoureux base to increase the theoretical plates of separation and maximize molecular impedance. This is the smaller of the two heads Delta-9 offers, but can easily distill 1 kg of botanical oils an hour. The length of the condenser was extended beyond typical units on the market for more surface area to condense vapors when distilling at rapid rates. The head is configured with 3 ground glass joints to minimize loss in vacuum pressure. The thermometer port is designed to work with high temperature 10/30 ground glass units and is equipped with 24/40 joints for combining with round bottom flasks and cow receivers.
