This specific liner combination offers excellent chemical resistance and provides a reliable seal, crucial for storing sensitive reagents or volatile substances.

The cap size is standardized at 48-400, a common threading that allows for potential aftermarket cap compatibility if ever needed, though the provided caps are robust. Each unit is supplied with caps already attached, simplifying the unboxing and immediate usage process. Furthermore, pressure-sensitive identification labels are included with each case, a thoughtful addition for organization and traceability in a busy environment. The ordering information specifies that these bottles are supplied as a Case of 144, offering substantial quantity for demanding workflows.

Performance & Functionality

In terms of core function, these bottle beakers excel at mixing, measuring, and storing. The 120 mL capacity is ideal for preparing small to medium batches of solutions, and the clear graduations in mL and ounces allow for reasonably accurate measurements without needing a separate graduated cylinder for every task. This ability to mix and measure in the same container significantly streamlines laboratory procedures.

The wide mouth is a significant performance enhancer. It allows for easy addition of solids, efficient stirring, and simple emptying without the frustration of material clinging to the sides or narrow necks. The pulp/vinyl-lined phenolic cap provides a secure closure, effectively preventing evaporation of volatile liquids and protecting contents from atmospheric contamination. This reliability is crucial for maintaining the integrity of sensitive samples or reagents over time.

The primary strength of these units lies in their all-in-one functionality and dependable sealing.
