Frequently Asked Questions
1. What are the benefits of using PEEK fingertight fittings?
PEEK fingertight fittings from Trajan allow for easy, hand-tightened connections that can typically withstand pressures up to 5,000 psi, eliminating the risk of over-tightening with tools.
2. Why is HPLC PEEK tubing color-coded?
The industry-standard color-coding (e.g., Red for 0.005", Yellow for 0.007") allows researchers to immediately identify the internal diameter of the tubing to prevent incorrect flow calculations.
3. Can I use these fittings with stainless steel tubing?
While PEEK fittings are versatile, they are specifically optimized for use with PEEK tubing to ensure a polymer-to-polymer seal that protects sensitive port threads.
4. Are Trajan PEEK accessories compatible with all HPLC brands?
Yes, standard 10-32UNF and 6-40UNF threads are designed for universal compatibility with the majority of HPLC and UHPLC systems on the market.
