LeafSaver - Optimized sampling for small Eukaryotic organisms

The Ahlstrom LeafSaver collection card is an innovative, field-ready solution designed for the efficient collection, preservation, and transport of small Eukaryotic organisms, including plants, fungi, insects, and parasites. Whether in the lab or in remote field locations, LeafSaver simplifies the process of biological sample collection for a wide range of molecular and taxonomic studies.

Engineered with a protective cover, LeafSaver allows for live collection and direct application of organisms onto the specialized collection paper, eliminating the need for complex preparations beforehand.

Our collection paper is made from pure cotton material and treated with chemicals to ensure long-term preservation of nucleic acids at ambient temperatures for over two decades.

LeafSaver's innovative design features four distinct areas, enabling the collection of multiple samples of the same nature or repeated samples of identical specimens (replicates). This not only enhances result accuracy but also facilitates higher quantities of DNA recovery.

DNA-free card for higher accuracy of the results

Ambient-Temperature Preservation LeafSaver allows DNA (nucleic acids) from plants, fungi, insects, and parasites to be collected, transported, and stored at ambient temperature — eliminating the need for freezing or refrigeration (cold-chain logistics). This simplifies storage and transport significantly.
Easy to Use — Ideal for Fieldwork

LeafSaver is designed for simplicity. This straightforward collection process requires minimal preparation and no specialized equipment, making it particularly suited for field collections or remote environments.
Simplified Logistics & Environmental Benefits

Without needing cold storage or plastic wrappings (envelopes or bags), logistics become both simpler and more cost-effective, while also cutting plastic usage and environmental impact. The cards can even be shipped via regular mail.
Multi-Sample Capability

LeafSaver features multiple distinct sampling areas, allowing collection of different specimens or replicates on the same card. This enhances accuracy and enables higher DNA yields.
