| 成果简介 | NOVELTY - The test tube has a structure (1) with a lid made with a cylindrical upper portion distinguished by the structure of the test tube is made in the form of a graduated measuring oblique cylinder. The upper edges of the structure are made sharp and form an acute angle with the inner sides. The longitudinal grooves are made on the inner surface of the upper portion of the cylinder, so as providing the ability to move the cover (2) relative to the base. The ratio between the radius of the base, the minimum height and the maximum height of the oblique cylinder is 1:4:5. USE - Test tube used in chemical, physical and biological laboratories, for collecting and storing soil samples. ADVANTAGE - The test tube improves the operating conditions and obtains reliable results of the sample analysis, ensures the simplicity of sample collection without the use of additional unit for sample collection, eliminates errors associated with both determining the amount of substance required for the sample and ensures tightness and safety of the collected soil sample. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the test tube. 1Structure 2Cover 3Pointed edge of cylinder 5Lock of cover to cylinder 6Indicator |
