The PEEK (Polyether Ether Ketone) digestive vessel outer shell is a critical component in laboratory settings, particularly in microwave digestion systems. It is designed for high-performance applications that require extreme durability, safety, and resistance to harsh conditions. The outer shell of the digestive vessel is made from advanced composite materials, featuring a blend of continuous basalt fiber and PEEK, providing enhanced properties compared to traditional PEEK materials.
The outer shell is constructed using continuous basalt fiber and PEEK composite, which offers superior mechanical and chemical resistance. Basalt fiber is known for its strength and thermal stability, while PEEK contributes to its outstanding resistance to chemicals and extreme temperatures. The outer surface of the shell can also be coated with polytetrafluoroethylene (PTFE) or perfluoroalkoxy (PFA), providing an additional layer of protection against chemical corrosion. This construction method ensures that the shell is not prone to explosion or cracking under high pressure, offering a significant improvement in overall performance compared to standard PEEK outer vessels.
The PEEK composite outer shell exhibits exceptional pressure resistance, withstanding up to 100 MPa (approximately 14,500 psi). Its high thermal stability allows it to function at temperatures as high as 300°C. These properties ensure safe and efficient operation, even under extreme conditions. Furthermore, the material's excellent microwave transparency enhances the heating process, ensuring rapid and uniform heating, which is essential for effective digestion in laboratory applications.
PEEK outer shells are commonly used in conjunction with microwave digestion systems, where they play a crucial role in ensuring the safety and efficiency of the digestion process. The inner vessel, made from a modified PEEK and glass fiber composite, complements the outer shell by offering high microwave transparency and pressure resistance. This combination allows the inner vessel to withstand up to 6000 psi, while the continuous fiber composite versions can handle pressures up to 10,000 psi. These features ensure safe and reliable operation, even in extreme conditions, making them ideal for applications in high-pressure, high-temperature digestion processes.
The PEEK digestive vessel outer shell, reinforced with continuous basalt fiber and coated with PTFE or PFA, represents a significant advancement in materials technology for laboratory equipment. Its superior pressure resistance, high thermal stability, and excellent chemical resistance make it a reliable choice for demanding applications, particularly in microwave digestion systems. The enhanced safety and performance of this outer shell ensure its widespread use in laboratories where high-pressure and high-temperature conditions are standard.
