Ultrasonic Freeze Drying Systems for Laboratory-Scale Spray Freeze Drying
Sono-Tek ultrasonic spray technologies enable precise laboratory-scale spray freeze drying for researchers developing advanced formulations, nanomaterials, and biologics. In this R&D-focused application, our ultrasonic atomization modules integrate directly with customer-supplied freeze dryers and lyophilization equipment, providing controlled droplet formation that supports improved morphology, reduced drying time, and high-quality spray freeze-dried powders.
Ultrasonic spray freeze drying is used to enhance the freeze-drying process by generating uniform droplets that freeze rapidly, improving sublimation efficiency and final product consistency.
Ultrasonic Precision for Spray Freeze Drying and Lyophilization
Ultrasonic atomization produces a fine, consistent aerosol of droplets that enter the freeze-drying process with highly controlled size and distribution. This results in more predictable ice crystal formation, reduced mechanical stress during freezing, and improved rehydration behavior after drying.
Researchers can tune spray freeze drying outcomes through adjustments to:
- Droplet size and aerosol density
- Formulation feed rate
- Atomization energy
- Freezing rate prior to primary drying
- Final moisture content following secondary drying
These variables influence powder morphology, flow characteristics, and stability for applications ranging from biologics to nanomaterials.
Typical Applications in Ultrasonic Spray Freeze Drying
Sono-Tek ultrasonic atomization modules support laboratory-scale spray freeze drying for:
- Biologics, proteins, and sensitive pharmaceuticals
- Vaccine adjuvant systems that benefit from minimal aggregation
- Nanoparticles and nanostructured materials
- Polymer-based formulations
- Specialty compounds requiring uniform drying behavior
- Early-stage drug delivery research requiring controlled powder properties
This method provides fine control over ice crystal structure, sublimation pathways, and final particle morphology.

Ultrasonic Atomization Module for Laboratory Integration
The primary solution Sono-Tek provides for spray freeze drying is our compact ultrasonic atomization module, commonly configured using the ALIGN platform. This modular ultrasonic system:
- Generates a consistent ultrasonic spray for liquid formulations
- Connects to user-supplied pumps, reservoirs, and freeze-drying equipment
- Supports a range of frequencies and droplet sizes
- Enables controlled spray freeze drying studies without requiring a full coating system
- Is easily adapted to benchtop or enclosed laboratory setups
This flexible arrangement makes it well suited to research teams who need precise ultrasonic atomization inside their existing laboratory-scale freeze-drying processes.
Proven Use in Scientific Research
Ultrasonic spray freeze drying has been referenced in peer-reviewed studies demonstrating benefits such as:
- Improved preservation of biologic activity after drying
- Reduced aggregation in alum-adjuvanted vaccine formulations
- Enhanced morphology and rehydration of nanoparticle powders
- Controlled aerosol formation for consistent drying kinetics
These outcomes highlight the value of ultrasonic atomization in achieving uniform droplets and stable freeze-dried products.
