Glass reactor (crystallizer), designation ZSK-50, with a glass vessel, heating jacket and agitator. The reactor is intended for chemical processes — mixing, heating and crystallization — and suits the chemical and pharmaceutical industries as well as pilot and laboratory work. The glass vessel allows visual control of the process, and the lid has multiple ports (for dosing, a thermometer, a condenser and more). The agitator is driven by a Marzorati (Italy) geared motor. Mounted on a supporting metal stand. The machine is used and sold as seen (per the photographs), in working order. Personal inspection and collection on site are possible.
