When selecting adapters for microfluidic applications, ensuring chemical compatibility is important for maintaining system integrity and performance. Nylon adapters are an excellent choice due to their good chemical resistance, as well as exceptional tensile and tear strength.
However, like all materials, Nylon has its limitations, and not every chemical is compatible with it. Therefore, understanding compatibility is essential for preventing degradation and ensuring safety. In this guide, we present a comprehensive table of chemical compatibility for Nylon adapters. This table, based on the chemical compatibility data (at 21°C) provided by Masterflex®, is designed to help engineers, technicians, and researchers quickly determine whether Nylon is suitable for their specific applications.
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
- Superscript 1 = Satisfactory up to 22°C (72°F)
- Superscript 2 = Satisfactory up to 48°C (120°F)
🚨 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.
