Standard vessels are manufactured to meet USP physical dimensions and have a perfectly rounded hemispherical bottom. Select PEAK vessels with a unique cone shape molded into the bottom to improve hydrodynamics, preventing cone-shaped formations of material at the base of the vessel under the paddle. Footed plastic vessels are an economical alternative to glass. They feature feet which allow them to stand upright independently.

Glass vessels offer good thermal conductivity as well as excellent resistance to scratching. A unique serial number is acid etched on the vessel.

PEAK vessels do not comply with USP specifications and cannot be substituted in existing applications.
