A common process for removing water from foods, pharmaceuticals and other products for storage and transportation is lyophilization, or more commonly called freeze drying. A critical component for this process is a vacuum source, the most reliable and consistent option being a vacuum pump.
Welch offers a broad range of freeze dryer pump solutions for processes involving either aqueous or acidic/organic samples, optimized for handling those materials with internal surface protection that increases corrosion resistance and product lifespan. We offer a great variety of pump sizes and accessories to meet all freeze drying process needs.
