It is of the greatest importance to produce high quality samples and analysis results, along with minimized risk of infection to staff. Greiner Bio-One can offer a complete range of evacuated blood collection tubes made out of virtually unbreakable PET-plastic. All of them are equipped with a unique safety cap, which also offers maximum security to healthcare workers. Coagulation is a critical testing area proving to be a challenge to some manufacturers.
