Similar in design to AF-0720 but without delivery adapter. Lower 3-way valve has been replaced with a single 0-4mm Chem-Vac™; Chem-Cap®; valve for draining distillate back into the flask. The uptake tube has one row of vigreux indentations, while the 14/20 top outer joint has been eliminated. Temperature can be measured by using a 2-neck flask with a thermocouple or thermometer adapter. The delivery tube has two 2mm PTFE straight bore stopcocks that can be operated in a way to purge the receiving vessel with inert gas. Capacity of solvent storage area is approx 250mL with a 24/40 top outer and a 24/40 lower inner standard taper joints.
