The Holland Green Science Preseva Plus -25°C freezer is designed for general low temperature freezing or frozen storage applications. With a temperature range down to -25°C, it ensures the proper conditions to preserve delicate products such as freeze-dried preparations, botanical extracts, and biological samples.

The "Plus" in the product name means this freezer features 21 shelves instead of the standard 4, providing significantly more storage space for samples or pre-production freezing of products. It holds up to 42 trays from the Xiros Mikro freeze dryer, making it the ideal companion for pre-freezing batches before lyophilization — shortening total freeze dry process time by 6 to 10 hours.

All Preseva Plus freezers have passed complete life testing to ensure safety and reliability for long-term operation in critical storage applications.
