Test tube caps, Labocap, silver, 12/13 mm.

These caps for test tubes are used in microbiological, biotechnological and bacteriological laboratories. They are mainly used for protection against falling dirt into it and guarantee the required sterilizable, but not hermetic seal. The built-in springs made of chromium steel make the caps cling firmly on the tubes and ensure the required airflow.
