Real-World Testing: Putting Whatman Fta Plantsaver Card PK100 WB120065 Fta Plantsaver Card PK100, Pack of 100 to the Test
First Use Experience
My initial testing of the FTA Plantsaver Cards occurred in a rather typical scenario for me: an outdoor research plot. The objective was to collect leaf samples from a variety of native flora, with the intent of later performing DNA extraction and sequencing. The process of applying the plant tissue to the card was straightforward. I simply pressed a fresh leaf segment directly onto the card’s surface, and the initial adherence was promising. I then exposed a few of the cards to ambient humidity and light for a couple of days before transferring them to a controlled lab environment for storage.
Unlike some disposable lab supplies that feel overly delicate, these Whatman cards possessed a satisfying tactile quality. They felt designed to withstand a bit of rough handling, which is crucial when you’re out in the field. I encountered no immediate issues; the cards absorbed the necessary plant material without smearing excessively, and the unique surface seemed to facilitate direct contact and initial drying. I noted that unlike some alternatives that rely on simple pressing, these cards are engineered for more than just drying; they are designed to stabilize the DNA.
Extended Use & Reliability
Over several weeks, I used these FTA Plantsaver Cards for multiple sampling expeditions. I intentionally subjected some cards to slightly less-than-ideal conditions, including brief exposure to light rain and storage in a field pack for over a month before reaching the lab. The material consistently held up, showing no signs of degradation or compromise in its ability to hold the plant tissue.
The durability of the cards has been impressive. Even after repeated pressing of leaf samples, the card surface remained intact, without significant fraying or tearing, which is something I’ve experienced with lesser quality substrates. Maintenance is essentially non-existent beyond proper storage before and after sample collection. For lab-based storage, I simply placed the cards in standard archival sleeves or folders. Compared to my previous experiences with basic blotting paper or even some commercially available sample collection kits, these specialized cards offer a clear advantage in terms of both immediate sample capture and long-term DNA preservation, which translates to greater reliability for downstream genetic analysis.

Specifications
The Whatman Fta Plantsaver Card PK100 WB120065 Fta Plantsaver Card PK100, Pack of 100 is essentially a specialized porous paper designed for the collection and stabilization of nucleic acids from biological samples. The key specification here is the FTA technology, which inherently lyses cells and denatures proteins upon contact, thereby inactivating nucleases and preventing DNA degradation. Each card is formatted for easy handling and consistent sample application, and the pack contains 100 individual cards. This bulk packaging is standard for consumables in research settings and offers a cost-effective solution for projects requiring numerous samples. The material itself is a proprietary blend, optimized for rapid liquid uptake and efficient DNA binding. The dimensions of each card are practical for fitting into standard laboratory storage systems, though specific measurements are not provided in the basic product description, the typical size is comparable to a standard business card, making them easy to handle and file.
These specifications are critical because they directly impact the success of downstream molecular applications. The FTA technology means that samples can be collected, dried, and stored at ambient temperature for extended periods, drastically reducing the need for refrigeration or freezing equipment, which is a significant logistical and cost advantage, especially for fieldwork. The 100-pack bulk format is standard and economical for routine sample collection, ensuring that researchers have an ample supply for their projects without frequent reordering. The specific material composition guarantees that the DNA is not just dried onto the surface but chemically stabilized, preserving its integrity for later analysis.
Performance & Functionality
In terms of core function, the FTA Plantsaver Card excels at its primary purpose: collecting and stabilizing plant DNA. The immediate effect upon contact with plant tissue is noticeable; the cellular components seem to integrate into the card matrix rapidly. This rapid stabilization prevents degradation, which is the most crucial aspect for reliable genetic analysis. I found that the yield and quality of DNA extracted from samples stored on these cards were consistently high, even after several months of ambient storage. This level of performance is what sets these cards apart from simpler blotting papers or even basic desiccation methods.
The main strength of these cards is undoubtedly their integrated stabilization chemistry. It performs its function reliably, providing peace of mind that the genetic material is protected. A potential weakness, as noted in some product descriptions, is the added processing charges and the possible loss of valuable plant tissue due to the nature of the treatment. While the loss of tissue is minimal with proper application, the card itself becomes the sample medium, meaning the original physical sample is not recovered for other analyses. However, for the specific purpose of DNA preservation, this functionality is precisely what makes it effective. It meets and often exceeds expectations for DNA stabilization in non-ideal conditions.
Design & Ergonomics
The design of the Whatman Fta Plantsaver Card PK100 WB120065 Fta Plantsaver Card PK100, Pack of 100 is deceptively simple but highly effective. The cards are manufactured from a robust material that feels durable enough to handle, yet porous enough to quickly absorb and dry biological samples. The surface is treated with the proprietary FTA chemistry, which is the active component in stabilizing nucleic acids. The layout typically includes designated areas for writing sample information directly onto the card, a practical feature for fieldwork and laboratory organization.
Ergonomically, these cards are a pleasure to use. They are a convenient size, easy to hold and manipulate with one hand if necessary, which is often the case when collecting samples in challenging field conditions. The material does not feel overly slick or difficult to grip, even with gloved hands. The consistent texture and uniform porosity across each card ensure predictable sample uptake and drying. There’s virtually no learning curve; the application is as simple as pressing the sample onto the card, making it accessible to researchers of all experience levels.
Durability & Maintenance
The durability of the FTA Plantsaver Cards is a significant advantage for anyone working outside of a fully controlled laboratory environment. These cards are designed to be rugged, resisting tears and punctures even when subjected to the rigors of field collection. Their inherent chemical stabilization properties also mean that once the sample is applied and dried, the DNA is protected from environmental factors like moisture and temperature fluctuations, contributing to long-term sample integrity.
Maintenance is practically nil for these consumable items. Once the plant tissue is applied and the card has dried, it can be stored at room temperature indefinitely without degradation of the DNA. The only “maintenance” required is proper storage of the unused cards in their original packaging to prevent premature exposure to the stabilizing agents or environmental contaminants. From my experience, these cards are built to last for the intended purpose, and I haven’t encountered any failure points in the card material itself; the primary consideration is the correct handling and application of the plant sample.
Accessories and Customization Options
The Whatman FTA Plantsaver Cards are designed as a standalone consumable. The pack of 100 units is the primary offering, and there are no specific accessories that come bundled with them. However, it’s important to note that these cards are designed to integrate seamlessly with a laboratory’s existing workflow. They can be used with any of the FTAA Plantsaver bags or inserts (either the square or rectangular type) using the slide valve or the Whatman ez-clean system, as mentioned in the product description. These optional accessories are geared towards larger-scale processing or specific sample handling protocols, offering enhanced containment or ease of transfer for multiple samples.
While not direct accessories for the cards themselves, the proprietary DNA extraction kits designed for use with FTA paper are essential complements. These kits are optimized to efficiently release the stabilized DNA from the card matrix, ensuring high yields and purity suitable for PCR, sequencing, and other downstream applications. Therefore, while the cards themselves are a singular item, their utility is amplified by compatible extraction protocols and optional handling accessories that can streamline workflow in a busy research setting.
