Manifold dryers make up a large majority of the lyophilizers that we carry and are popular in various laboratory applications.

In shelf freeze dryers, the product is placed onto shelves, so they can often accommodate larger quantities. In this design, the product is placed in a container and affixed to valves. They're generally employed in research applications and not for commercial use. Manifold dryers are ideal for labs that need to freeze-dry a small amount of various individual samples. You can use flasks, vials and trays with manifold, shelf-freeze or combination chambers. Product shelf chamber: Some product shelf chambers are better suited to different sample types and sizes.Condenser size is usually measured in liters. The size of the lyophilizer will also impact the size of its condenser, which determines how much liquid you can sublimate before needing to defrost - in other words, how much you can sublimate in one run. Size: You'll find used lyophilizers for sale in compact benchtop models, perfect for small spaces, pilot models for more precise or large-capacity operations, and massive production-level models common in food preparation activities.We can categorize our used freeze dryers based on their size or the type of product shelf chamber: But there are many different types of lyophilizers, each with different capabilities. Lyophilizers excel in their role because the dehydration occurs through sublimation, so the product does not lose its structure. They freeze the material, reduce pressure and add heat to sublimate water molecules off of the sample, with each task controlled by various mechanisms within the instrument, such as the vacuum system, condenser or refrigeration system. Types of LyophilizersĪll lyophilizers work on the same principle of removing water from an object. If you're looking for used freeze dryers, you'll have to carefully consider your application and what it demands from a lyophilizer. Lyophilizers were hard at work even back in World War II, where they would freeze-dry blood plasma for easier transportation. You can find them in the development of biopharmaceuticals, food product preparation and various types of research. They affect a wide range of products and can help with everything from preserving perishable items to making substances easier to transport. Lyophilizers find their way into many different types of labs. Types of Lyophilizers - What to Consider - Popular Manufacturers Used Freeze Dryers for Sale
