Ahlstrom launches LeafSaver, an innovative solution for the collection and ambient temperature preservation of plants, fungi, insects, and parasites


In the dynamic landscape of biological research, efficient preservation of nucleic acid samples is crucial for unlocking insights into the genetic makeup of various organisms. However, this task can prove challenging, particularly in the case of plant specimens where degradation can occur rapidly. For this purpose, Ahlstrom, a global leader in life sciences and molecular diagnostics, announces the extension of its specimen collection cards portfolio with the addition of LeafSaver, a card designed for the collection, transport, and storage of plants, fungi, insects, and parasites.

Unlike traditional preservation methods, which often require freezing or refrigeration, Ahlstrom LeafSaver allows DNA preservation directly on the card at ambient temperature. This eliminates the need for specialized storage conditions, simplifying logistics, bringing sustainability benefits and reducing costs associated with cold chain transportation. The card can also be shipped by regular mail without the need for plastic wrapping, such as a plastic envelope or bag.

Ease of use is at the core of the LeafSaver card design. Researchers simply need to place the plant specimen on the designated area of the card, allow it to air dry, and then close and seal the card securely. This streamlined process makes it ideal for fieldwork, remote expeditions, or any scenario with limited access to laboratory facilities.

“The LeafSaver card represents a significant advancement in plant, fungi, insect, and parasite DNA preservation technology," says Jacques Lafon, EVP Healthcare at Ahlstrom. "Its innovative design and ease of use empower researchers to collect and preserve high-quality DNA samples with minimal difficulty, ultimately accelerating discoveries across various fields, including agriculture, environmental science, botany, and beyond."

Ahlstrom LeafSaver is developed to accommodate a wide range of species and sample types. Its collection paper ensures long-term preservation of nucleic acids at ambient temperature for over two decades and reliable DNA recovery over time. Its user-friendly design facilitates the collection, avoids cross-contamination, and protects the biological samples. To better meet customers’ needs, Ahlstrom LeafSaver is customizable upon request.
