Additional Info:
Reduce adsorption and improve recovery for larger‑volume, sensitive samples using deactivated inserts designed for 4 mL vial workflows.
9504S‑03ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to minimize active surface sites. This treatment improves recovery of polar and adsorption‑prone analytes while maintaining the durability and consistency required for higher volume analytical methods.
These inserts provide a 700 µL total fill volume with approximately 500 µL usable volume and a residual volume near 8 µL with most autosamplers. The precision conical tip concentrates sample at the bottom for improved recovery and consistent needle access, even in larger volume applications where control and reproducibility are critical.
Polypropylene springs keep the insert properly centered within the vial, reducing needle misalignment and helping prevent insert breakage during repeated injections. Manufactured in an ISO 9001:2015 certified facility, these inserts ensure consistent quality and dimensional accuracy across batches.
