Freeze-drying is not a quick process, and cycles can take a few days and up to a week to complete. It requires a good balance of several factors, and a good understanding of freeze-drying concepts is crucial to achieving a successful process.

In this guide, Buchi provides technical notes and answers to frequently asked questions to support successful freeze-drying for a wide range of applications. This includes how to choose the right hardware, important sample preparation steps, and how to perform freeze-drying when using solvents other than water.

Lyophilization is commonly used as a solution for sample preparation, sample formulation, or to improve storage properties. A wide variety of systems, with a range of sizes, capabilities, and configurations, is available on the market. No system will be suitable for every possibility, and it is important to define what the freeze dryer will be needed for, so that an appropriate instrument can be found.

Explore insights from BUCHI on how to balance individual factors to successfully freeze-dry, and learn how to address misunderstandings through technical notes and answers to frequently asked questions.

In this application note, BUCHI provides a complete pre-treatment solution for the determination of polycyclic aromatic hydrocarbons (PAHs) in environmental samples (e.g. sludge and soil, etc.) prior to quantitative analysis, including freeze-drying the sample, extraction of analyte compounds, clean-up, and concentration of the extracts.

The world of beauty has been evolving over the years and the sector of cosmetics and personal care is expanding. Creativity in development, marketing, health and well-being is a must for any cosmetics company. In the highly competitive industry, products must differentiate and use of innovative technologies can help achieve this goal.

Freeze drying is the most gentle process to dry various types of perishable materials. The principle of freeze drying is based on the direct transition of a substance from the solid to the gaseous state, called sublimation. Initially, the product is frozen and then dried by sublimation in an environment of reduced pressure. The low pressure enables direct changeover of the frozen solvent into vapor. In most freeze drying applications, the solvent to be removed from the product is water. However, other solvents can be used to a certain extent, such as ethanol.
