Maximize Sample Recovery with RSA™ Low Volume Inserts!
9502S‑02N‑RS inserts are engineered for high‑precision, low‑volume analysis where sample conservation and injection accuracy are critical. Manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, these inserts deliver superior chemical resistance, extremely low extractables, and outstanding consistency.
Each insert features a mandrel‑formed, precision conical tip that concentrates sample at the bottom, ensuring maximum recovery and reliable needle access. With a residual volume of approximately 2 µL (depending on autosampler), these inserts are optimized for efficient use of valuable or limited samples.
Why Choose RSA™ Reduced Surface Activity Glass?
Minimized Adsorption for Accurate Results The reduced surface activity (RSA™) treatment lowers interaction with basic compounds, reducing sample loss and improving reproducibility.
Ultra‑Low Extractables & Metal Content Designed for sensitive analyses, RSA™ glass minimizes contamination risks and virtually eliminates delamination.
