https://www.sainingsci.com/product/molecular-detection/pcr8-strip-tube-with-cap.html The quest for a more durable PCR strip tube begins with understanding the materials from which they are made. Typically, PCR strip tubes are crafted from polypropylene, a thermoplastic polymer known for its resistance to heat, chemicals, and fatigue. However, the durability of these tubes can be enhanced through several innovative approaches. Firstly, the manufacturing process itself can be refined. By employing advanced extrusion techniques, manufacturers can create tubes with a more uniform wall thickness, reducing the likelihood of stress points that could lead to cracks or breakage. This uniformity also ensures that the tubes maintain their structural integrity across a wide range of temperatures, which is crucial for PCR applications.
