Breaking Down the Features of VWR Vwr Bottle Br Cl Qal 500mlcs12 QLFB15900223

The VWR Vwr Bottle Br Cl Qal 500mlcs12 QLFB15900223 is designed with practical laboratory applications in mind, offering a robust and accurate solution for volumetric needs. The product name itself breaks down into key characteristics: “VWR” signifies the reputable manufacturer, “Bottle Br Cl” likely refers to a borosilicate glass bottle, “Qal” suggests quality, and “500mlcs12” indicates a 500 ml capacity with a case of 12 units. The QLFB15900223 is the specific catalog number for identification.

Specifications

This pack contains twelve 500 ml borosilicate glass bottles. Borosilicate glass is chosen for its excellent thermal shock resistance and superior chemical inertness, making it ideal for handling a wide range of substances without leaching or contamination. The bottles feature clearly etched graduations for volumetric measurement, though they are not calibrated to the precision of a volumetric flask; these are designed for general-purpose use where high accuracy is not paramount but good estimation is required. The 500 ml capacity is a versatile size, suitable for preparing medium-sized batches of reagents or storing larger aliquots.

The choice of 500 ml capacity is a good middle ground, offering enough volume for many common laboratory procedures without becoming excessively bulky or heavy. For tasks requiring higher precision, one would opt for a volumetric flask of the same capacity, which undergoes stricter calibration. However, for general solution preparation, storage, or transfer where exact volume is less critical than reliable containment and clear measurement, this bottle excels. Its inclusion as a 12-pack makes it cost-effective for labs that go through this size of container regularly.

Performance & Functionality

In its primary function as a container for liquids, the VWR Vwr Bottle Br Cl Qal 500mlcs12 QLFB15900223 performs exceptionally well.
