Additional Info:
Reduce adsorption and improve injection consistency for challenging samples with deactivated wide‑cone insert design.
9502S‑02CPD‑K inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to minimize active surface sites. Combined with a thicker wall design and wider conical tip, these inserts help reduce both analyte adsorption and bubble formation, delivering improved recovery and reproducibility for sensitive workflows.
The wider conical geometry improves sample stability at the tip while maintaining efficient needle access. Residual volume is approximately 2.5 µL with most autosamplers. Polypropylene springs keep inserts centered within the vial, reducing the risk of needle misalignment and minimizing insert breakage during repeated injections.
Manufactured in an ISO 9001:2015 certified facility, these inserts provide consistent quality across large production batches. The combination of deactivated glass chemistry and optimized geometry offers a strong balance of performance, durability, and reliability compared to standard and basic silanized insert designs.
