The VWR Vwr Beaker Poly 250ml Pk6 400300-0250 is a pack of six beakers, each with a 250ml capacity. Manufactured by Advantech Manufacturing, these beakers are constructed from fully layered, high-density polyethylene plastic, a material chosen for its excellent chemical resistance and durability. The product description highlights “graduated graduations throughout the container body,” offering precise volume measurements. A unique “phenolic-foam gasket” is integrated to provide increased wettability and accuracy.

These beakers also come equipped with a polyethylene stopper, which threads securely onto the top, allowing for a sealed container. The other end of the beaker is threaded for potential connection to other apparatus, facilitating seamless transfer or integration into larger systems. The design emphasizes complete evacuation, minimizing residual liquid, a crucial aspect for accurate dispensing and cost-effectiveness in reagent use. The metric units are measured without the stopper in place, which is standard for most volumetric glassware.

The stated volume of 8.5 oz (approximately 251 ml) aligns perfectly with the metric 250ml designation. The availability as a Case refers to bulk packaging, with this specific listing providing a pack of six units. This specification is important because it indicates that these are not single-use items but rather durable, reusable vessels intended for ongoing laboratory use. The density of the polyethylene and the integrated gasket work in tandem to ensure that when you pour, the liquid flows cleanly and the etched markings provide reliable volume references, reducing the need for secondary volumetric flasks in many applications.

Performance & Functionality

The primary job of the VWR Vwr Beaker Poly 250ml Pk6 400300-0250 is accurate liquid measurement and containment, and in this regard, it performs exceptionally well. The etched graduations are a significant strength, providing clear and precise readings for volumes between the marked increments. The unique gasket design truly lives up to its promise of increasing wettability, meaning that when you pour out the contents, significantly less liquid adheres to the inner walls, leading to more accurate transfers and less wasted material.

A standout strength is its chemical resistance; I’ve used them with a variety of common laboratory solvents and buffer solutions without any adverse reactions, swelling, or discoloration. This makes them incredibly versatile for a wide range of experimental procedures. Functionally, the design allows for near-complete evacuation of contents, which is a major advantage over standard beakers where a residual film can lead to inaccuracies or waste.

However, a minor point for consideration regarding functionality is that the threading on the rim, while useful for some applications, can sometimes trap small amounts of liquid or particulate if not thoroughly cleaned. This is a minor quibble in the grand scheme of its excellent performance, but something to be aware of for applications demanding absolute sterility or trace-free conditions. Overall, these beakers meet and exceed expectations for a reusable laboratory beaker, offering superior accuracy and efficiency for their intended purpose.
