Additional Info:
Improve recovery and reduce adsorption in larger vial formats with deactivated inserts designed for sensitive analytical workflows.
9504S‑01ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to minimize active surface sites. This improves recovery of polar and adsorption‑prone analytes while maintaining excellent consistency through a mandrel‑formed precision conical tip.
The precision tip concentrates sample at the bottom, providing approximately 250 µL total fill volume with about 150 µL usable volume and a residual volume near 3 µL in most autosamplers. This ensures reliable needle access and reproducible injections in LC‑MS and HPLC workflows.
The extended 6 × 38 mm design is optimized for 4 mL autosampler vials, allowing low‑volume sample handling within larger vial formats. Springs may be required depending on the autosampler and are sold separately; when used, they improve centering and reduce the risk of needle misalignment or insert breakage.
Manufactured in an ISO 9001:2015 certified facility, these inserts provide consistent dimensional accuracy and reliable performance across batches.
