For removing urine samples from beakers without risking contamination.
1. Unscrew the lid from the urine beaker.
2. Remove film from the lid.
3. Insert the vacuum-sample tube onto the extraction needle in the lid opening and press down.
4. The evacuated tube automatically extracts the sample quantity required.
5. The tube remains sealed so contamination is impossible.
The beaker can only be used in combination with the vacuum-sample tubes!
