Let’s Dive into Forensics Source Postmortem Adhesive Card Strip
The Forensics Source Postmortem Adhesive Card Strip is a specialized tool designed for crime scene investigation and forensic analysis. Offered by Forensics Source, these strips are intended for the collection of trace evidence during postmortem examinations. At a price of $37.99 for a pack of 50, they represent a potentially cost-effective solution for evidence gathering.
My work frequently involves meticulous collection of even the smallest details at sensitive scenes. Traditional methods can be cumbersome, especially when dealing with delicate or loosely adhered particles. I was seeking a more efficient and reliable method for collecting trace evidence, particularly fibers and other microscopic materials.
Upon receiving the package, the simplicity of the design was immediately apparent. The strips felt well-made, with a consistent adhesive coating. The compact size of the cards makes them easily portable and manageable in the field.
Having used similar products like electrostatic dust lifters, I was curious to see how these adhesive strips would compare in terms of effectiveness and ease of use. Electrostatic lifters can sometimes be overly sensitive, while traditional tape lifting can be messy and prone to contamination. I was hoping the Forensics Source Postmortem Adhesive Card Strip would offer a better balance of sensitivity and control. My initial impression was cautiously optimistic; the real test would be in their practical application.
Real-World Testing: Putting Forensics Source Postmortem Adhesive Card Strip to the Test
First Use Experience
My first opportunity to use the Forensics Source Postmortem Adhesive Card Strip came during a mock crime scene setup for a training exercise. The scene involved various surfaces, including fabric, carpet, and hard plastics, each seeded with trace evidence like fibers, hairs, and simulated skin cells. I wanted to observe how the strips would perform on different types of material.
In dry conditions, the strips performed admirably, easily lifting fibers and particulate matter from the various surfaces. The adhesive proved to be strong enough to capture even small amounts of debris but not so aggressive as to damage the underlying surfaces. I was particularly impressed by their performance on carpet and upholstery, where they effectively collected deeply embedded fibers that would have been difficult to retrieve with other methods.
I did observe one issue: the strips became less effective in areas with even minimal moisture. A damp cloth used as part of the scene rendered the strips nearly useless in that area. While this wasn’t entirely unexpected, it highlighted the importance of dry conditions for optimal use.
Extended Use & Reliability
After several weeks of using the Forensics Source Postmortem Adhesive Card Strip across multiple training scenarios, their overall reliability proved consistent. The adhesive remained effective over time, and the cards themselves showed no signs of degradation despite repeated handling. Storage is key; keeping them sealed in their original packaging prevented contamination and ensured optimal performance.
Durability-wise, the strips are single-use by design, but the backing material held up well to handling and pressure during evidence collection. This minimized the risk of tearing or contamination during the critical process of lifting and transferring evidence.
Cleaning the strips is not an option, as they are single-use. The key is to ensure the target surface is as clean as possible before applying the strip to avoid irrelevant contaminants. Compared to the bulkier and more complex electrostatic lifting devices I’ve used previously, the Forensics Source Postmortem Adhesive Card Strip offers a simpler, more portable, and ultimately, more reliable solution for specific trace evidence collection scenarios.
Breaking Down the Features of Forensics Source Postmortem Adhesive Card Strip
Specifications
The Forensics Source Postmortem Adhesive Card Strip is a deceptively simple but critically important tool. Each pack contains 50 individual adhesive strips, designed for single-use application. The adhesive is a pressure-sensitive acrylic polymer, carefully formulated to lift trace evidence without causing damage to the underlying surface.
The card backing is made from a chemically inert paper stock. This provides a stable and contamination-free support for the adhesive layer. The dimensions of each strip are approximately 2″ x 4″, offering a reasonable surface area for evidence collection while remaining manageable in tight spaces.
These specifications matter because they directly impact the reliability and integrity of evidence collection. The choice of adhesive is crucial for capturing a wide range of trace materials, from fibers and hairs to microscopic particles. The inert backing ensures that no extraneous materials are introduced during the collection process, preserving the integrity of the evidence.
Performance & Functionality
The Forensics Source Postmortem Adhesive Card Strip excels at its primary function: the collection of trace evidence. In controlled testing environments, the strips consistently lifted a wide range of materials, including cotton and synthetic fibers, human and animal hairs, and various particulate matter. The pressure-sensitive adhesive provides an optimal balance between adhesion strength and ease of removal, minimizing the risk of damage to delicate evidence.
One area for potential improvement lies in the lack of a grid system or measuring scale on the card backing. This would aid in documenting the precise location of collected evidence on the strip.
Overall, the Forensics Source Postmortem Adhesive Card Strip meets and exceeds expectations for its intended purpose. It provides a reliable, efficient, and cost-effective solution for trace evidence collection in forensic investigations.
Design & Ergonomics
The design of the Forensics Source Postmortem Adhesive Card Strip is intentionally minimalistic. The cards are lightweight and easy to handle, even when wearing gloves. The smooth, flat surface of the backing provides a comfortable grip and allows for consistent pressure to be applied during evidence collection.
The lack of any complex mechanisms or moving parts contributes to the overall user-friendliness of the product. There is virtually no learning curve involved; the process is as simple as peeling the backing, applying the adhesive to the target surface, and carefully lifting to collect the evidence.
Durability & Maintenance
Given their single-use design, long-term durability is not a primary concern. However, the materials used in the Forensics Source Postmortem Adhesive Card Strip are of sufficient quality to withstand normal handling and storage conditions. As long as the strips are kept in their original packaging and protected from extreme temperatures and humidity, they should remain effective for an extended period.
Maintenance is non-existent, as the strips are intended to be discarded after each use. This eliminates the risk of cross-contamination between samples and simplifies the overall evidence collection process.
Accessories and Customization Options
The Forensics Source Postmortem Adhesive Card Strip is a self-contained product with no external accessories required for its primary function. There are no customization options available.
The simplicity is a strength; compatibility issues with other tools or equipment are a non-issue. The strips are designed to be used in conjunction with standard forensic tools, such as evidence bags, magnifying glasses, and documentation equipment.
