Precision Systems Sample Tube 0.2 ml Glass Sealed Pack of 12 Tubes

Precision Systems 2022 Sample Tube 0.2 ml is a specialized glass capillary tube designed for measuring very small volumes of fluid in an osmometer. This extremely low volume indicates the tube is designed for samples where the amount of fluid is highly limited, such as in clinical diagnostics or trace analysis. The tubes are essential for the operation of freezing point osmometers, where the sample is supercooled and then frozen. The small, glass tube facilitates rapid and controlled heat transfer to measure the freezing point depression, which is the principle used to determine the sample's osmolality.
