This machine is best suited for industries such as pharmaceutical, chemical, biological, and materials science, and is commonly used to support 2L to 5L rotary evaporators or glass reactors for distillation and concentration. Its core advantages include a high-strength anti-corrosion material body, flexible dual-tap or quad-tap configurations, and a maximum vacuum level of up to 0.098 Mpa. While providing stable vacuum, it also circulates cooling water to reaction devices, making it an indispensable high-efficiency and energy-saving equipment.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003c!-- Section I --\u003e\n\u003ch2\u003eI.
