Basic Mobility Freeze Dryer

Basic Mobility Freeze Dryer – QualiFD™ M Series

The QualiFD™ M Series Basic Mobility Freeze Dryer is a floor-standing Freeze Dryer Machine designed for flexible lab use and routine lyophilization. Built with integrated caster wheels, the system moves easily between benches, pilot areas, and shared laboratory spaces without interrupting established workflows. It supports consistent drying performance across applications in medicine, pharmaceuticals, biological research, chemistry, and food processing where controlled handling and repeatability are essential.

This mobility-focused freeze dryer features a compact, single-unit structure designed for space efficiency, reduced leakage risk, and straightforward operation. The cold trap and work surface are constructed from stainless steel, supporting corrosion resistance and simplified cleaning. Product-contact components are inert, aligning with GLP-oriented laboratory requirements.

A wide cold trap opening combined with a pre-freeze function supports daily processing needs without reliance on a separate low-temperature freezer. The integrated touchscreen control system allows real-time monitoring and records key process curves for analysis, documentation, and reporting, helping maintain consistent and traceable results.

Applications

Pharmaceutical and Medical Laboratories:
Freeze drying supports extended storage of temperature-sensitive samples and intermediates while maintaining product integrity. The top-press configuration allows vials to be dried and sealed under vacuum for secure storage. Continuous monitoring of vacuum levels, cold trap temperature, and product temperature curves helps maintain process stability and supports consistent method development.

Biology and Microbiology Research:
Lyophilization is widely used for preserving enzymes, biological reagents, and other sensitive materials that degrade in liquid form. The ampoule-tube configuration is suitable for preserving microorganisms such as bacteria and fungi. A mobile base allows easy repositioning within shared lab environments, keeping the unit stable during operation while improving workflow flexibility.

Chemistry and Specialty Materials:
Freeze drying is applied to solutions, suspensions, and porous materials where low-temperature solvent removal is required. Manifold configurations allow connection of external bottles or vials and can integrate with concentration workflows when needed. Stainless steel construction supports routine cleaning and compatibility with commonly used laboratory solvents.

Food and Ingredient Development:
In food R&D, freeze drying is used for sensitive ingredients where heat-based drying may alter texture or aroma. The standard tray configuration supports small-batch processing of liquids, semi-solids, and solids for pilot-scale trials. Mobility enables teams to use the system across multiple applications without the need for a fixed installation space.

Standards

Theory and Method

Freeze drying removes solvent from a frozen product under reduced pressure. The process begins with freezing, followed by primary drying where ice transitions directly into vapor and is captured by the cold trap. Secondary drying then reduces bound moisture to achieve lower residual levels suitable for storage.

Cold trap temperature and chamber pressure play a key role in vapor capture efficiency and overall drying rate. Monitoring product temperature helps ensure the sample remains within formulation limits during primary drying. Once the cycle is complete, the chamber is brought back to atmospheric pressure before unloading and final sealing.
