When selecting tubing for microfluidic applications, ensuring chemical compatibility is crucial for maintaining system integrity and performance. PharmaPure® tubing offers excellent biocompatibility and chemical resistance. It is ideal for medical, pharmaceutical, and biotechnological settings.
Like all materials, PharmaPure has its limitations, and not every chemical is compatible with it. Understanding these compatibility issues is essential to prevent tubing degradation and ensure safety. This guide presents a comprehensive chemical compatibility table for PharmaPure tubing. This table, based on the chemical compatibility data (at 21°C) provided by Masterflex®, is designed to help engineers, technicians, and researchers quickly determine the suitability of PharmaPure for specific applications, ensuring reliable and long-lasting performance in various chemical environments.
Refer to this table to make informed choices and maintain the efficiency and safety of your system.
💡 The chemical compatibility rating key is as follows:
- A = Excellent chemical compatibility (no effect)
- B = Good chemical compatibility (minor effect: slight corrosion or discoloration)
- C = Fair (moderate effect: not recommended for continuous use; softening, loss of strength, swelling and/or shrinkage)
- D = Severe effect (not recommended for use; severe softening, swelling and/or shrinkage)
- N/A = No data available
🚨 The compatibility ratings provided in these tables are for general guidance only and may not be complete or accurate. They do not address potential contamination or changes in fluid properties due to tubing interaction. We do not guarantee the suitability of any material for specific purposes or the impact of tubing on fluid quality. For critical applications, conduct specific tests or seek expert advice.
