Streck is a leading global manufacturer of quality control and sample stabilization systems for clinical and diagnostic laboratories. The company develops innovative solutions to ensure sample integrity, including blood collection tubes, cell stabilization media, molecular and hematology controls, as well as products for flow cytometry, HbA1c analysis, and infectious disease diagnostics.

Streck’s technologies are based on proprietary cell stabilization and enable the reliable preservation of blood and body fluid samples over extended periods at room temperature. This reduces preanalytical variability and ensures reproducible, high-quality test results in laboratories worldwide.

Streck products are used in hematology, oncology, liquid biopsy, immunophenotyping, and molecular diagnostics, and help laboratories ensure quality throughout the entire analysis process—from sample collection to results.

IGZ Instruments AG is Streck’s official partner in Switzerland and provides customers with consulting, sales, and technical support to help them select and implement the right quality control and stabilization solutions.
