Safematic CDS-020 Automated Dehydration and Critical Point Drying System

Overview

Safematic CDS-020 Unique Features and Applications

• A fully automated hands-off process without the need of monitoring
• Researchers can start a process in the evening get your dried specimen in the morning.
• The CDS-020 has greater process reliability and traceability due to researchers being able to customize recipes and the system’s ability to process the tracking.
• Small footprint means less space required in the laboratory.
• The CDS-020 can handle samples up to 30mm in size.
• No use of refrigerants

Area of application

• Water-containing structures or moist samples (usually biological) can be altered or destroye during drying in air or in a vacuum.
• Critical point drying with the safematic CDS-020 is an efficient method to preserve these structures. The tangential forces of interfacial tension that occur during drying between water and air are avoided by transferring the liquid phase of CO2 into the gas phase without a phase transition. For this purpose, water is replaced by the solvent ethanol that is miscible with liquid CO2, as this can then be exchanged for CO2 again.
• The steps required to prepare any hydrated biological samples for SEM/TEM include fixation, dehydration, critical point drying, mounting, and coating with metal to improve electron conductivity of sample surface.
• The safematic Compact Drying System CDS-020 covers the steps of dehydration and critical point drying. The automated process produces repeatable high-quality results.
