RIA Test Tube

Conical-bottomed, leak-proof boats from Nayan International’s Ria Test Tubes prevent leaks and breakage during rapid centrifugation. As a Ria Test Tube Manufacturer, they are made of non-cytotoxic, medical-grade resin that enables users to see sample volume and colour rapidly.

HDPE caps come in two different styles. Flat caps contain an incorporated elastomeric sealing ring that stops leaks and maintains complete security for the sealed tubes. These caps are ideal for prolonged rocker incubations and chemical vortexing. Plug caps have a deep sealing region that offers a trustworthy seal for extended storage.

Liquids are kept in Ria Test Tubes during centrifugation, which quickly rotates the sample around a fixed axis to separate it into its parts.
