It boasts a 100ML capacity, making it ideal for a wide range of field and lab applications. The primary construction material is ultra-thin, polypropylene, chosen for its chemical resistance and durability.

Key to its functionality is the airtight silicone O-ring seal integrated into the lid. This feature ensures no leakage, crucial for preserving sample integrity and preventing spills, especially in dynamic field conditions. The cylindrical body is made from fully tempered, high-quality, double-wall paper taper, a description that seems to indicate a robust layered construction providing superior strength and rigidity.

The top molded graduation offers clear, easy-to-read markings, allowing for precise volume estimation. Furthermore, the bottom of the cylindrical graduation is grooved to prevent leakage of liquids, a subtle but important design element that enhances sealing. The specification mentions that the “outer diameter of the cylindrical graduation is clearly visible from the top,” which I interpret as excellent visibility of the fill level from a top-down perspective.

The plug-seal, a critical component for maintaining the airtight seal, is molded from 100% pure, lead-free, FDA-grade, heavy-walled glass with a rounded bottom to prevent freezing. This detail is somewhat contradictory to the polypropylene body, suggesting the plug-seal might be a separate component or that the description has conflated different product lines. However, if the plug-seal is indeed glass, it adds a layer of chemical inertness. The product detail also states, “These are the only glassware items that cannot be autoclaved,” which reinforces the idea of a glass component or a component incompatible with autoclaving processes.

The base is drilled for permanent imprinting, a feature likely more relevant for institutional use for identification or tracking, but it speaks to the manufacturer’s attention to detail.
