Additional Info:
Improve recovery and simplify workflows for adsorption‑sensitive samples using self‑aligning deactivated inserts.
9502S‑03ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to reduce active surface sites. This treatment minimizes analyte interaction, improving recovery and consistency for polar, basic, or adsorption‑prone compounds.
The self‑aligning design eliminates the need for springs by allowing the insert to center itself within the vial. Slightly taller than standard inserts, it rests securely at the bottom of the vial, ensuring stable positioning and consistent needle access. The conical tip concentrates the sample at the bottom for efficient recovery, while the wider cone geometry helps reduce bubble formation during filling.
These inserts provide a 300 µL total fill volume with approximately 200 µL usable volume and a residual volume near 2 µL with most autosamplers. Manufactured in an ISO 9001:2015 certified facility, they deliver reliable consistency across batches for reproducible analytical results.
