<p>The polymeric envelope of conditioning microorganisms/cells to absorb liquid cryogenic agent for sample conservation, comprises thin tube in which metal ballast is disposed inside the tube. The metal ballast is in the form of cord, ball and ring. The ballast has first part with round section and second part with oval section. The envelope in the thin tube has welded portion placed against the fixed ballast. The envelope exists between the ballast and the tube of an element for maintaining the ballast and the tube to a predetermined position. The polymeric envelope of conditioning microorganisms/cells to absorb liquid cryogenic agent for sample conservation, comprises thin tube in which metal ballast is disposed inside the tube. The metal ballast is in the form of cord, ball and ring. The ballast has first part with round section and second part with oval section. The envelope in the thin tube has welded portion placed against the fixed ballast. The envelope exists between the ballast and the tube of an element with a projecting portion for maintaining the ballast and the tube to a predetermined position. The ballast is arranged at an end of the thin tube. The thin tube has a predetermined external diameter, and the ballast has a predetermined internal diameter lower than the tube external diameter. The ballast is maintained to deform the thin tube. Visual electronic device for identification of the microorganism/cells associated to the ballet.</p> |
