In vitro diagnostics (IVD) plays a key role in the healthcare ecosystem and selecting the right tubing for your IVD analyzer is essential for achieving accurate and reliable results. With so many options available, it can be overwhelming to determine which tubing is best suited for your needs. With over 355 years of material expertise, Saint-Gobain Medical has developed several standard tubing formulations that are specifically designed to meet the needs of the medical market, including Tygon®, Bio-Sil®, and Versilon® tubing. In this article, we'll explore the different types of medical tubing and what to consider when selecting custom tubing solutions for your diagnostic process.

Improve In Vitro Diagnostics Process Performance

Within in vitro diagnostics, the performance criteria needed for each workflow step is unique, requiring specific tubing for each stage. Recognizing that selecting the ideal tubing can be a daunting task, we have categorized tubing into three groups: sample processing tubing, waste disposal tubing, and pump tubing. Within each of these groups, we’ve identified the attributes and specifications critical for ideal performance.

Transfer and pump tubing recommendations for IVD applications

Samples, Reagents Tubing Recommendations

When it comes to fluid management of samples and reagents, selecting the right tubing is crucial for achieving accurate results. Tubing formulations for this purpose should demonstrate low adsorption, excellent chemical compatibility, high flexibility to navigate complex configurations within a small footprint, and bioinertness, particularly for the analysis of blood samples. At Saint-Gobain Medical, we offer six (6) material formulations that are frequently used for samples and reagents processing tubing, each with specific benefits that are discussed in detail below.

  • Very flexible 

 TYGON® E-3603 (Flexible Thermoplastic)

  • Good bending radius 
  • Transparent 
  • Very flexible 

 TYGON® MPF-300 (TPU) 

  • Transparent
  • Different norms validated 
  • Flexible 
  • Good chemical resistance if cleaning is needed 
  • No plasticizer
