Additional Info:
Improve recovery and minimize adsorption in moderate‑volume workflows using deactivated inserts designed for 4 mL vial applications.
9504S‑04ND 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 enhances recovery of adsorption‑prone analytes while maintaining the durability and consistency required for routine and sensitive analytical methods.
These inserts feature a conical tip that concentrates the sample at the bottom, improving recovery and ensuring consistent needle access. With a 300 µL total fill volume, approximately 200 µL usable volume, and a residual volume near 3 µL with most autosamplers, this design provides an effective balance between capacity and performance.
Polypropylene springs keep the insert 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 offer consistent quality and reproducibility across batches.
