BCT & Preservatives

Protect your samples with advanced blood collection tubes and preservatives.

Our range of blood collection tubes (BCT) and stabilization reagents ensures the integrity of your samples during transport and storage. By controlling pre-analytical variables, you can trust that your results remain reliable and reproducible.

Designed for both clinical and research use, these solutions help preserve nucleic acids, proteins and cellular components through analysis. This reduces degradation and variability, supporting consistent and accurate results.

With reliable stabilization under various conditions and extended room temperature stability, our products simplify sample handling and improve laboratory efficiency.

Choose Streck blood collection tubes and stabilization reagents for trusted sample stability.
