Additional Info:
Enhance sensitivity and reduce adsorption with advanced RSA‑Pro™ low volume inserts designed for demanding analytical workflows.
9502S‑02ND‑RS inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass that is further surface treated to increase hydrophobicity and reduce analyte interaction. This combination of RSA glass chemistry and additional surface treatment provides exceptional deactivation, improving recovery of low abundance and adsorption‑prone compounds.
Each insert features a mandrel‑formed, precision conical tip for consistent geometry and maximum sample recovery. Residual volume is approximately 2 µL (depending on autosampler), with about 200 µL usable volume. Polypropylene springs keep the insert centered in the vial, reducing the risk of needle contact and improving injection reliability.
The enhanced surface treatment distinguishes these inserts from standard silanized options by offering greater consistency from insert to insert and more complete deactivation. This makes them especially effective for sensitive analyses involving proteins, peptides, and trace‑level compounds. Manufacturing in an ISO 9001:2015 certified facility ensures high reproducibility and quality control.
